Аннотация:Although traditionally sulfate-reducing bacteria (SRB) have been considered strict anaerobes, they are capable of survival in the biotopes affected by oxygen, such as activated sludge, cyanobacterial mats, water column, bottom sediments, etc. The Black Sea is a meromictic water body. Its anaerobic, sulfide-rich deep waters do not mix with the upper, oxic water layer. Fluorescent in situ hybridization revealed viable SRB cells (Desulfotomaculum, Desulfovibrio, and Desulfobacter) in both anaerobic and aerobic zones of the Black Sea. We therefore attempted to obtain SRB enrichments and pure cultures from the aerobic water column of the Black Sea.
