Abstract

 

Results of the studies on the occurrence of bacteria displaying particular physiological properties in coastal Lake Gardno are presented. Most numerous groups among neustonic and planktonic bacteria studied were ammonifying and producing hydrogen sulphide from organic compounds strains. Nitrifying bacteria were not numerous among isolated strains. It was demonstrated that significant differences in the abundance of individual physiological groups bacteria existed in water layers, stations and seasons.

 

Key words: coastal lake, bacterineuston, bakterioplankton, physiological properties
