- Аннотация: From December 2009 to December 2010, the total abundance of bacteria, the abundance of bacteria with electron transport chain, the abundance of viable saprotrophic bacteria, and the concentration of chloro- phyll a were studied in water samples from lakes Svyatoe, Beloe, and Chernoe in Kosino–Ukhtomskoe district, Moscow City. The abundance of bacteria with active electron transport chain (CTC+bacteria) and its seasonal variations in Kosinskie Lakes are studied for the first time. Those lakes were found to contain well-developed and actively functioning heterotrophic bacterioplankton, the abundance of which have increased considerably since the 1930s–1940s. The seasonal dynamics of bacterioplankton has also changed. The largest absolute abundance of CTC+bacteria in lakes Svyatoe and Beloe was recorded in summer and autumn (from August to November). The abundance peak of CTH+bacteria in Lake Svyatoe was recorded in September and that in Lake Beloe, in October. The abundance of CTC+bacteria also showed a peak in April. In Lake Chernoe, the abun- dance of CTC+bacteria was much less than in lakes Svyatoe and Beloe; its maximums were recorded in Decem- ber 2009 and April 2010. The share of CTC+bacteria in the total abundance of bacteria was 2.4–19.2% in Lake Svyatoe, 1.8–63.0% in Lake Beloe, and 0.96–22.5% in Lake Chernoe. Significant correlations were found to exist in all three lakes between the abundance of active bacterioplankton fraction and chlorophyll a content of water.
