Study of lake fungi biodiversity in from the La Izvor lake (Chisinau municipality)

Abstract

The cultural and morphological features of the isolated fungal strains were studied. As a result of the research, representatives of 18 genera of fungi were found, these being: Penicillium, Aspergillus, Trichoderma, Alternaria, Fusarium, Botrytis, Monilinia, Mucor, Rhizopus, Acremonium, Cladosporium, Trichocladium, Phoma, Chaetomium, Stachybotrys, Talaromyces. In all studied samples, the most common genera of filamentous fungi proved to be Penicillium and Aspergillus, followed by the genera Trichoderma and Alternaria. Together these genera represent about 90% of the total number of isolated strains. It was found that depending on the place of isolation, the representatives of the genus Penicillium predominate in the water, and in the silt, and biofilm samples – the representatives of the genus Aspergillus.
