The seasonal variability of yeasts and yeast-like organisms in water and bottom sediment of the Szczecin Lagoon.

Qualitative and quantitative analysis of samples of water and bottom sediment from the Szczecin Lagoon were carried out from May, 1996 to December, 1997. Isolates of yeasts and yeast-like fungi from water samples reached maximum counts in July whereas sediment samples revealed highest counts in May. Qualitative analysis showed that Candida famata and Rhodothorula rubra were dominant species. As they are typical of strongly eutrophic water their presence indicates that the Szczecin Lagoon is significantly polluted by industrial and municipal sewage.
