Some biochemical properties of fungi from genera Rhodotorula and Trichosporon isolated from Sulejow Reservoir bath water

The hydrolytic activity of Rhodotorula and Trichosporon strains isolated from Sulejów Reservoir water and sediments were studied. Also tolerance of high concentrations of natrium chloride and biogenic compounds was evaluated. Fungi from genera Rhodotorula and Trichosporon showed the activity of 12 and 10 from 19 hydrolases of API Zym test, respectively. Tolerance tests showed high resistance of Rhodotorula glutinis to hypertonic saline solutions and very high resistance of both Rhodotorula and Trichosporon strains to nitrate, ammonium and phosphate compounds. These properties of fungi may influence the distribution and the quantity of fungi in aquatic reservoirs.
