The population density of actinomycetes in the samples of light sierozem from the Kopet Dag piedmont plain (75 km from Ashkhabad, Turkmenistan) reaches hundreds of thousand CFU/g soil. The actinomycetal complex is represented by two genera: Streptomy

In the sor (playa) solonchaks of chloride and sulfate–chloride salinity (the content of readily soluble salts is 0.9–1.0%) in the delta of the Khara River discharging into Lake Elton, the number of mycelial actinobacteria (actinomycetes) is low (

The population density, size, and biomass of the soil bacteria from a mountain meadow-steppe soil of Tajikistan and a light sierozem of the Negev Desert have been analyzed using the method of “cascade” filtration. It was shown that, when cultivat

Soddy-podzolic, gray forest, brown forest, primitive Antarctic soils, typical chernozems, and solonchaks were studied. Many ultrafine bacterial cells, along with fine ones, were found in all the soils studied. The gray forest, brown forest, and primi

Several hundred bacterial strains belonging to different taxa were isolated and identified from the digestive tracts of soil and compost earthworms. Some physiological and biochemical properties of the bacteria were characterized. The majority of int

In a model experiment, the abundance of microorganisms was monitored for half a year in native and mechanically comminuted samples of live and dead sphagnum using the method of luminescent microscopy. The effect of the mechanical comminution was more

In the studied mesodepressions, the total microbial biomass in the gray forest and chernozemic soils decreases by two-three times under the impact of hydrogen flux from the subsoil horizons and soil waterlogging. The biomass decrease is especially pr

The viability of bacteria in oligotrofic bogs and fens was determined by the luminescent microscopy method with the help of a two-component fluorescent dye (L7012 LIVE/DEAD). Living bacterial cells were found in the entire peat profiles. Their portio
