Microbiological Processes in Small Lakes to the North of Ladoga

ABSTRACT

The numbers and total activity of bacteria were shown to be consistent with the trophic level of six small lakes of Karelia in summer. The activity of microflora in autumn was lower than in summer. Parameters of the functional activity of bacteria were nearly identical in oligotrophic and mesotrophic lakes and were higher in eutrophic humified lakes. However, two eutrophic lakes markedly differed in seasonal variation of bacterial synthesis and decomposition. It was assumed that standard coefficients cannot be used to calculate the rate of microbiological processes in all lakes, and that the specific factors of individual lakes must be rather considered.
