Yeast-like fungi possessing bio-indicator properties isolated from the Łyna river

Abstract

Yeast-like fungi isolated in the Łyna river are constant components of microflora of inland waters. Every increase in their number indicates progress in the process of eutrophication and accumulation of organic and inorganic pollutans. The fungi <i>Candida aibicans, Pichia guilliermondii, P. anomala, Rhodotorula glutinis i Trichosporon beigelii</i>, potentially pathogenic apperred in water with high content of municipal sewage, but <i>T. aquatile</i> - in the clean waters only.
