Аннотация: The number, structure, and physical state of the microbial communities in highmoor and low moor peat bogs were compared. Distinct differences in these characteristics were revealed. The microbial bio mass in the highmoor peat exceeded that in the lowmoor peat by 2–9 times. Fungi predominated in the highmoor peat, whereas bacteria were the dominant microorganisms in the lowmoor peat. The micromyc etal complexes of the highmoor peat were characterized by a high portion of darkcolored representatives; the complexes of the lowmoor peat were dominated by fastgrowing fungi. The species of the Penicillum genus were dominant in the highmoor peat; the species of Trichoderma were abundant in the lowmoor peat. In the former, the bacteria were distinguished as minor components; in the latter, they predominated in the saprotrophic bacterial complex. In the highmoor peat, the microorganisms were represented by bacilli, while, in the lowmoor peat, by cytophages, myxobacteria, and actinobacteria. The different physiological states of the bacteria in the studied objects reflecting the duration of the lag phase and the readiness of the metabolic system to consume different substrates were demonstrated for the first time. The relationships between the trophic characteristics of bacterial habitats and the capacity of the bacteria to consume substrates were established.
