Thirty-six samples of both aerobic and anoxic activated sludge were taken from 2 MBR treating domestic wastewater. Over a period of eight months 2 samples from each plant were taken per month. The samples were prepared for count and definition of fungi. The obtained data show that, sixty species belonging to 27 genera were collected from activated sludge samples under aerobic and anoxic conditions. Regarding to the fungi definition, under aerobic condition the Geotrichum was found at (8.8%) followed by Penicillium (75.0%), Yeasts (65.7%) and Trichoderma (55.5%), while Yeasts (77.1%) Geotrichum candidumand Penicillium (61.1%) species were the most prevalent in anoxic activated sludge. The results indicate that activated sludge is habitat for growth and sporulation of different groups of fungi, both saprophytic and pathogenic. ER -
