Аннотация: In July 2017, at the time of the massive development of freshwater crustaceans Bosmina longirostris in the aerobic zone of the meromictic Lake Trekhtzvetnoe, green contents were found in their digestive system. The spectrum of the extract from the crustaceans revealed a narrow light absorption peak with a maximum at 655 nm corresponding to the peak of bacteriochlorophyll absorption of green sulfur bacteria living in the anaerobic part of the chemocline. This is the first evidence of nutrition of zooplankton from the aerobic zone by anoxygenic phototrophic bacteria from the anaerobic zone of the chemocline of meromyctic lakes. It confirms the importance of the chemocline microbial community for the entire water body ecosystem.
