Fungal microflora biodiversity as a function of pollution in Oued Sebou (Morocco)

An inventory of the fungal microflora present in sediments collected at 11 sites along Oued Sebou has been established. The influence of some climatic parameters (temperature, rainfall) and of pollution on the composition of the fungal communities has been questioned. Emericella nidulans, Eurotium amstelodami, Neosartotya fesheri var. glabrum (Ascomycetes), Dreschslera biseptata (Dematiacæ;), Penicillium citrinum (Mucedinaceæ) and Phoma sp. (Sphæropsidale) can be considered as strains sensitive to pollution. Penicillium janthelinum, Trichoderma koningii (Mucedinaceæ) and Candida albicans (Yeast) were found only at the most polluted sites ; Talaromyces flavus (Ascomycete) Rhodotorula rubra, Saccharomyces cerevisiæ (Yeasts) and Fusarium oxysporum (Tuberculariales) were more often found at heavily polluted sites than at lightly polluted ones.
