Multidrug efflux has been described for many organisms, including bacteria and fungi as part of their drugs resistance strategy. The potential use of probiotic bacteria can be considered as a new alternative in the prevention or cure of oral cavity diseases. In this study, different Bacillus strains isolated from the environment were isolated and characterized using biochemical and molecular procedures. The inhibitory activity against different pathogenic bacteria and yeast strains was tested using diffusion agar assay method. Our data revealed that the tested strains have an antimicrobial effect against the pathogenic strains such as Streptococcus mutants. The inhibitory effect was variable depending from the probiotic and pathogenic strains. The obtained result demonstrated that Bacillus can be used as a potential candidates probiotic and help in the prevention and treatment of oral infections, including dental caries, periodontal disease and halitosis. Our data, partly encourage the use of probiotic strains because they do not produce acid which can contribute to faster installation decay and these are spore-forming bacteria that can withstand the stress of the oral cavity (acids, alkalis, and salty foods). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=probiotic" title="probiotic">probiotic</a>, <a href="https://publications.waset.org/abstracts/search?q=pathogenic%20bacteria" title=" pathogenic bacteria"> pathogenic bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=yeast" title=" yeast"> yeast</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20cavity" title=" oral cavity"> oral cavity</a> </p> <a href="https://publications.waset.org/abstracts/1415/inhibitory-effect-of-potential-bacillus-probiotic-strains-against-pathogenic-bacteria-and-yeast-isolated-from-oral-cavity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1415.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">378</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Optimization of the Numerical Fracture Mechanics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Hentati">H.

Results show that the increase of ambient temperature leads to an increase of Tpz and NO<sub>x</sub> emissions rate and a decrease of cycle efficiency and UHC emissions. The CO emissions decrease with the raise of residence time, while NO<sub>x</sub> emissions rate increases and UHC emissions rate decreases.

The combined system includes a bio-filter composed of LECA® (lightweight expanded clay aggregate) followed by a vertical up-flow constructed wetland planted with Iris pseudacorus and Typha Latifolia. Applied two hydraulic retention times (HRTs) with two different plants types showed that a bio-filter planted with Typha Latifolia has an optimum removal efficiency for degradation of organic matter and transformation of nitrogen and phosphate at HRT of 30 h. The optimum removal efficiency of biochemical oxygen demand (BOD), chemical oxygen demand (COD), and suspended solids (SS) ranged between 48-65%, between while the nutrients removal was in the range of 70% to 90%. Fecal coliforms dropped by three to four orders of magnitude from their initial concentration, but this steel does not meet current regulations for unlimited irrigation.

Indeed, a productive R&D activity, a good strategy, and innovation are originally supplementary benefits that increase the value of the business. Is this ‘value-added’ closely linked to innovation? The purpose of our research is to Meta-analyze the results of 56 empirical studies in order to explain the overall effect of innovation on performance of small and medium-sized enterprises. In order to justify the differences in the results, we look for the moderating factors that may affect the innovation-performance relationship. We find a positive and significant relationship between innovation and performance in small and medium-sized enterprises. The results also note a positive relationship between entrepreneurial orientation, research and development (R&D), and performance in SMEs. In addition, innovation has a strong impact on performance measured both with accounting and market index. The originality of the article is based on a rigorous synthesis, based on several statistical tools, of an important subject of research in finance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=innovation" title="innovation">innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurial%20orientation" title=" entrepreneurial orientation"> entrepreneurial orientation</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-analysis" title=" meta-analysis"> meta-analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=moderator%20variables" title=" moderator variables"> moderator variables</a> </p> <a href="https://publications.waset.org/abstracts/92038/effect-of-innovation-and-its-determinants-on-the-performance-of-small-and-medium-sized-enterprises" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92038.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">286</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Robust Features for Impulsive Noisy Speech Recognition Using Relative Spectral Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hajer%20Rahali">Hajer Rahali</a>, <a href="https://publications.waset.org/abstracts/search?q=Zied%20Hajaiej"> Zied Hajaiej</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Ellouze"> Noureddine Ellouze</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The goal of speech parameterization is to extract the relevant information about what is being spoken from the audio signal.

The above-mentioned techniques were tested with impulsive signals under various noisy conditions within AURORA databases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auditory%20filter" title="auditory filter">auditory filter</a>, <a href="https://publications.waset.org/abstracts/search?q=impulsive%20noise" title=" impulsive noise"> impulsive noise</a>, <a href="https://publications.waset.org/abstracts/search?q=MFCC" title=" MFCC"> MFCC</a>, <a href="https://publications.waset.org/abstracts/search?q=prosodic%20features" title=" prosodic features"> prosodic features</a>, <a href="https://publications.waset.org/abstracts/search?q=RASTA%20filter" title=" RASTA filter"> RASTA filter</a> </p> <a href="https://publications.waset.org/abstracts/8911/robust-features-for-impulsive-noisy-speech-recognition-using-relative-spectral-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8911.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">425</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Mechanical-Reliability Coupling for a Bearing Capacity Assessment of Shallow Foundations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amal%20Hentati">Amal Hentati</a>, <a href="https://publications.waset.org/abstracts/search?q=Mbarka%20Selmi"> Mbarka Selmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tarek%20Kormi"> Tarek Kormi</a>, <a href="https://publications.waset.org/abstracts/search?q=Julien%20Baroth"> Julien Baroth</a>, <a href="https://publications.waset.org/abstracts/search?q=Barthelemy%20Harthong"> Barthelemy Harthong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The impact of uncertainties on the performance assessment of shallow foundations is often significant. The need of the geotechnical engineers to a more objective and rigorous description of soil variations permitting to quantify these uncertainties and to incorporate them into calculation methods led to the development of reliability approaches. In this context, a mechanical-reliability coupling was developed in this paper, using a program coded in Matlab and the finite element software Abaqus, for the bearing capacity assessment of shallow foundations. The reliability analysis, based on the finite element method, assumed both soil cohesion and friction angle as uncertain parameters characterized by normal or lognormal probability distributions. The inherent spatial variability of both soil properties was, then, taken into account using 1D stationary random fields. The application of the proposed methodology to a shallow foundation subjected to a centered vertical loading permitted to highlight the proposed process interest. Findings proved the insufficiency of the conventional approach to predict the foundation failure and a high sensitivity of the ultimate loads to the soil properties uncertainties, mainly those related to the friction angle, was noted. Moreover, an asymmetry of both displacement and velocity fields was obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mechanical-reliability%20coupling" title="mechanical-reliability coupling">mechanical-reliability coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=shallow%20foundation" title=" shallow foundation"> shallow foundation</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20fields" title=" random fields"> random fields</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20variability" title=" spatial variability"> spatial variability</a> </p> <a href="https://publications.waset.org/abstracts/18588/mechanical-reliability-coupling-for-a-bearing-capacity-assessment-of-shallow-foundations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18588.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">661</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Pharmaceutical Evaluation of Five Different Generic Brands of Prednisolone </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asma%20A.%20Ben%20Ahmed">Asma A.

Use of generic medicines has been increasing in recent years, primarily as a cost saving measure in healthcare provision. Generic medicines are typically 20 – 90 % cheaper than originator equivalents. Physicians often continue to prescribe brand-name drugs to their patients even when less expensive pharmacologically equivalent generic drugs are available. Because generics are less expensive than their brand-name counterparts, the cost-savings to the patient is not the only factor that physicians consider when choosing between generic and brand-name drugs. Unfortunately Physicians in general and Libyan Physicians in particular tend to prescribe brand-name drugs, even without evidence of their therapeutic superiority, because neither they nor their insured patients bear these drugs’ increased cost with respect to generic substitutes. This study is to compare the quality of five different prednisolone tablets of the same strength from different companies under different trade names: Julphar, October pharma, Akums, Actavis, Pfizer compared them with pure prednisolone reference (BPCRS). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality%20control" title="quality control">quality control</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceutical%20analysis" title=" pharmaceutical analysis"> pharmaceutical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=generic%20medicines" title=" generic medicines"> generic medicines</a>, <a href="https://publications.waset.org/abstracts/search?q=prednisolone" title=" prednisolone "> prednisolone </a> </p> <a href="https://publications.waset.org/abstracts/19693/pharmaceutical-evaluation-of-five-different-generic-brands-of-prednisolone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19693.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">514</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Heterogeneous Photocatalytic Degradation of Ibuprofen in Ultrapure Water, Municipal and Pharmaceutical Industry Wastewaters Using a TiO2/UV-LED System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Jallouli">Nabil Jallouli</a>, <a href="https://publications.waset.org/abstracts/search?q=Luisa%20M.%20Pastrana-Mart%C3%ADnez"> Luisa M.

Samples of ultrapure water (UP) and a secondary treated effluent of a municipal wastewater treatment plant (WWTP), both spiked with IBU, as well as a highly concentrated IBU (230 mgL-1) pharmaceutical industry wastewater (PIWW), were tested in the TiO2/UV-LED system. Three operating parameters, namely, pH, catalyst load and number of LEDs were optimized. The process efficiency was evaluated in terms of IBU removal using high performance liquid chromatography (HPLC) and ultra-high performance liquid chromatography coupled to tandem mass spectrometry (UHPLC-MS/MS). Additionally, the mineralization was investigated by determining the dissolved organic carbon (DOC) content. The chemical structures of transformation products were proposed based on the data obtained using liquid chromatography with a high resolution mass spectrometer ion trap/time-of-flight (LC-MS-IT-TOF). A possible pathway of IBU degradation was accordingly proposed. Bioassays were performed using the marine bacterium Vibrio fischeri to evaluate the potential acute toxicity of original and treated wastewaters. TiO2 heterogeneous photocatalysis was efficient to remove IBU from UP and from PIWW, and less efficient in treating the wastewater from the municipal WWTP. The acute toxicity decreased by ca. 40% after treatment, regardless of the studied matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20toxicity" title="acute toxicity">acute toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibuprofen" title=" Ibuprofen"> Ibuprofen</a>, <a href="https://publications.waset.org/abstracts/search?q=UV-LEDs" title=" UV-LEDs"> UV-LEDs</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewaters" title=" wastewaters"> wastewaters</a> </p> <a href="https://publications.waset.org/abstracts/76746/heterogeneous-photocatalytic-degradation-of-ibuprofen-in-ultrapure-water-municipal-and-pharmaceutical-industry-wastewaters-using-a-tio2uv-led-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76746.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">255</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Practice, Observation, and Gender Effects on Students’ Entrepreneurial Skills Development When Teaching through Entrepreneurship Is Adopted: Case of University of Tunis El Manar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hajer%20Chaker%20Ben%20Hadj%20Kacem">Hajer Chaker Ben Hadj Kacem</a>, <a href="https://publications.waset.org/abstracts/search?q=Thouraya%20Slama"> Thouraya Slama</a>, <a href="https://publications.waset.org/abstracts/search?q=N%C3%A9jiba%20El%20Yetim%20Zribi"> Néjiba El Yetim Zribi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper analyzes the effects of gender, affiliation, prior work experience, social work, and vicarious learning through family role models on entrepreneurial skills development by students when they have learned through the entrepreneurship method in Tunisia.

The methodology used consists of estimating a panel of the nine main destinations of the Tunisian diaspora in Europe between 1994 and 2014 in order to better value the net effect of these migratory financial flows on unemployment through population growth. The empirical results show that the main factors explaining the decision to emigrate are the economic factors related mainly to the income differential, the demographic factors related to the differential age structure of the origin and host populations, and the cultural factors linked basically to the mastery of the language. Indeed, the stock of migrants is one of the main determinants of the transfer of migratory funds to Tunisia. But there are other variables that do not lack importance such as the economic conditions linked by the host countries. This shows that Tunisian migrants react more to economic conditions in European countries than in Tunisia. The economic situation of European countries dominates the numbers of emigrants as an explanatory factor for the amount of transfers from Tunisian emigrants to their country of origin. Similarly, it is clear that there is an indirect effect of transfers on unemployment in Tunisia. This suggests that the demographic transition conditions the effects of transferring funds on the level of unemployment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=demographic%20changes" title="demographic changes">demographic changes</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20migration" title=" international migration"> international migration</a>, <a href="https://publications.waset.org/abstracts/search?q=labor%20market" title=" labor market"> labor market</a>, <a href="https://publications.waset.org/abstracts/search?q=remittances" title=" remittances"> remittances</a> </p> <a href="https://publications.waset.org/abstracts/100738/remittances-unemployement-and-demographic-changes-between-tunisia-and-europe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100738.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Seismic Reflection Highlights of New Miocene Deep Aquifers in Eastern Tunisia Basin (North Africa)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mourad%20B%C3%A9dir">Mourad Bédir</a>, <a href="https://publications.waset.org/abstracts/search?q=Sami%20Khomsi"> Sami Khomsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hakim%20Gabtni"> Hakim Gabtni</a>, <a href="https://publications.waset.org/abstracts/search?q=Hajer%20Azaiez"> Hajer Azaiez</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramzi%20Gharsalli"> Ramzi Gharsalli</a>, <a href="https://publications.waset.org/abstracts/search?q=Riadh%20Chebbi"> Riadh Chebbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Eastern Tunisia is a semi-arid area; located in the northern Africa plate; southern Mediterranean side. It is facing water scarcity, overexploitation, and decreasing of water quality of phreatic water table. Water supply and storage will not respond to the demographic and economic growth and demand. In addition, only 5 109 m3 of rainwater from 35 109 m3 per year renewable rain water supply can be retained and remobilized. To remediate this water deficiency, researches had been focused to near new subsurface deep aquifers resources. Among them, Upper Miocene sandstone deposits of Béglia, Saouaf, and Somaa Formations. These sandstones are known for their proven Hydrogeologic and hydrocarbon reservoir characteristics in the Tunisian margin. They represent semi-confined to confined aquifers. This work is based on new integrated approaches of seismic stratigraphy, seismic tectonics, and hydrogeology, to highlight and characterize these reservoirs levels for aquifer exploitation in semi-arid area. As a result, five to six third order sequence deposits had been highlighted. They are composed of multi-layered extended sandstones reservoirs; separated by shales packages. These reservoir deposits represent lowstand and highstand system tracts of these sequences, which represent lowstand and highstand system tracts of these sequences. They constitute important strategic water resources volumes for the region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title="Tunisia">Tunisia</a>, <a href="https://publications.waset.org/abstracts/search?q=Hydrogeology" title=" Hydrogeology"> Hydrogeology</a>, <a href="https://publications.waset.org/abstracts/search?q=sandstones" title=" sandstones"> sandstones</a>, <a href="https://publications.waset.org/abstracts/search?q=basin" title=" basin"> basin</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=aquifers" title=" aquifers"> aquifers</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a> </p> <a href="https://publications.waset.org/abstracts/142805/seismic-reflection-highlights-of-new-miocene-deep-aquifers-in-eastern-tunisia-basin-north-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142805.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">178</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Obtaining Norms for Arabic Translated Version of the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) Neuropsychological Battery in Normal Elderly Omanis Attending a Tertiary Hospital in Oman</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Alobaidy">Ammar Alobaidy</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamees%20Alsawafi"> Lamees Alsawafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Malak%20Almawali"> Malak Almawali</a>, <a href="https://publications.waset.org/abstracts/search?q=Balqees%20Alabri"> Balqees Alabri</a>, <a href="https://publications.waset.org/abstracts/search?q=Hajer%20Alhamrashdi"> Hajer Alhamrashdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: There is scarce data in the literature concerning the use of Arabic version neuron psychological cognitive tests in the geriatric age group of the Omani population. Objectives: Our aim is to obtain norms for normal elderly Omanis assessed by The Consortium to Establish a Registry for Alzheimer's disease (CERAD) neuro psychological battery and to compare these norms with other studies in the literature. Methods: 84 attendants and visitors of in-patients at Sultan Qaboos University Hospital, elder than 55 years, were interviewed. All participants were assessed by Dementia Rating Scale & Geriatric Depression Scale to ensure the integrity of their activities of daily living and the absence of depression, respectively. The performance of all participants in the CERAD battery was rated by a single rater to optimize the inter-rater reliability. Results: The cut-point for average performance in CERAD battery is dependent on the age, sex, and level of education and cannot be set as a single cut-point for all elderly Omanis. Conclusion: This study has shown the effect of age, sex, and level of education on the cognitive performance of normal elderly Omanis. The normative data obtained from this study can be utilized to differentiate between the cognitive decline of normal aging and the cognitive impairment due to various neuro cognitive disorders in the elderly Omanis, and probably culturally similar Arabic speaking communities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CERAD" title="CERAD">CERAD</a>, <a href="https://publications.waset.org/abstracts/search?q=neuropsychological%20battery" title=" neuropsychological battery"> neuropsychological battery</a>, <a href="https://publications.waset.org/abstracts/search?q=normal%20aging" title=" normal aging"> normal aging</a>, <a href="https://publications.waset.org/abstracts/search?q=elderly%20Omanis" title=" elderly Omanis"> elderly Omanis</a> </p> <a href="https://publications.waset.org/abstracts/18881/obtaining-norms-for-arabic-translated-version-of-the-consortium-to-establish-a-registry-for-alzheimers-disease-cerad-neuropsychological-battery-in-normal-elderly-omanis-attending-a-tertiary-hospital-in-oman" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18881.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">371</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Biocontrol Effectiveness of Indigenous Trichoderma Species against Meloidogyne javanica and Fusarium oxysporum f. sp. radicis lycopersici on Tomato </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hajji%20Lobna">Hajji Lobna</a>, <a href="https://publications.waset.org/abstracts/search?q=Chattaoui%20Mayssa"> Chattaoui Mayssa</a>, <a href="https://publications.waset.org/abstracts/search?q=Regaieg%20Hajer"> Regaieg Hajer</a>, <a href="https://publications.waset.org/abstracts/search?q=M%27Hamdi-Boughalleb%20Naima"> M'Hamdi-Boughalleb Naima</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhouma%20Ali"> Rhouma Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Horrigue-Raouani%20Najet"> Horrigue-Raouani Najet</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, three local isolates of <em>Trichoderma</em> (Tr1: <em>T. viride</em>, Tr2: <em>T. harzianum</em> and Tr3: <em>T. asperellum</em>) were isolated and evaluated for their biocontrol effectiveness under <em>in vitro</em> conditions and in greenhouse. <em>In vitro</em> bioassay revealed a biopotential control against <em>Fusarium oxysporum</em> f. sp. <em>radicis lycopersici</em> and <em>Meloidogyne javanica </em>(RKN) separately. All species of <em>Trichoderma</em> exhibited biocontrol performance and (Tr1) <em>Trichoderma viride</em> was the most efficient. In fact, growth rate inhibition of <em>Fusarium oxysporum</em> f. sp. <em>radicis lycopersici</em> (FORL) was reached 75.5% with Tr1. Parasitism rate of root-knot nematode was 60% for juveniles and 75% for eggs with the same one. Pots experiment results showed that Tr1 and Tr2, compared to chemical treatment, enhanced the plant growth and exhibited better antagonism against root-knot nematode and root-rot fungi separated or combined. All <em>Trichoderma</em> isolates revealed a bioprotection potential against <em>Fusarium oxysporum</em> f. sp. <em>radicis lycopersici</em>. When pathogen fungi inoculated alone, Fusarium wilt index and browning vascular rate were reduced significantly with Tr1 (0.91, 2.38%) and Tr2 (1.5, 5.5%), respectively. In the case of combined infection with Fusarium and nematode, the same isolate of <em>Trichoderma</em> Tr1 and Tr2 decreased Fusarium wilt index at 1.1 and 0.83 and reduced the browning vascular rate at 6.5% and 6%, respectively. Similarly, the isolate Tr1 and Tr2 caused maximum inhibition of nematode multiplication. Multiplication rate was declined at 4% with both isolates either tomato infected by nematode separately or concomitantly with Fusarium. The chemical treatment was moderate in activity against <em>Meloidogyne javanica</em> and <em>Fusarium oxysporum f. sp. </em><em>radicis lycopersici</em> alone and combined. <p
