Abstract

The number and biomass of prokaryote microorganisms in the therapeutic mud from the saline Lake Tinaki-1 (Astrakhan oblast) were studied. In the therapeutic mud of this lake, the organic matter decomposition is performed by bacteria, whose number is 250 million/g, which is an order of magnitude lower than the number of bacteria in the soils of the Volga River delta. The therapeutic mud is of the chloride type of salinization. It has a low organic carbon content, which is related to the low bacterial population in it. Among the ecological-trophic groups of microorganisms in the mud of Lake Tinaki-1, halophilic ones prevail. The highest carbon content of the microbial biomass (0.06 mg/g) was characteristic of the therapeutic mud, which is interpreted as an organic horizon of the soil profile studied. The share of carbon of the microbial biomass in the carbon of the mud organic matter varied from 0.5 to 1.4%.
