Distribution of mycelial fungi in water bodies of the Volga region

Mycological analysis of water samples from the rivers of the Volga region showed that, in water samples taken from rivers in the territory of the Republic of Tatarstan, fungi of the genus Aspergillus were isolated in 15 % of samples, Cladosporium - 25 %, Fusarium - 21 %, Penicillium -13 %, Mucor - 2 %, Rodotorula - 24 %. Fungi of the genus Aspergillus - 23 %, Cladosporium - 31 %, Fusarium - 25 %, Penicillium - 18 %, Trichoderma - 14 %, Mucor - 12 % samples were sown in water samples taken from the water bodies of the Republic of Mari-El. In the Republic of Chuvashia, fungi of the genus Aspergillus - 23 %, Cladosporium - 17 %, Fusarium - 20 %, Penicillium - 22 %, Mucor - 8 % of water samples were isolated. Thus, an increased ammonium content was observed in water samples from the Mesha rivers - 2,08±0,42 mg/dm3, the Volga - 1,04±0,21 mg/dm3, and the Komarovo reservoir - 1,98±0,40 mg/dm3, with the value of the maximum permissible concentration for fishery purposes - 0,51 mg/dm3. An increased amount of sulfates in the summer season was observed in the Republic of Tatarstan in water samples from Lake Kaban -140,0±15 with the value of the maximum permissible concentration for fishery purposes - 100 mg/dm3, in the same samples, the maximum water hardness was recorded - 10,6±1,59 0J.
