Description
Summary:The microbiological characterization of the brown forest soils in the territory of the Botanical Garden-Institute of the Far East Division of the Russian Academy of Sciences in southern Primor'e is given. The high humus content and weakly acid reaction of these soils were shown to provide the optimal conditions for the development of bacteria. In the brown forest soils differing in the thickness of the humus horizons, all the ecologic-trophic groups of bacteria were present and the bacterial communities were highly diverse. The structure of the bacterial communities was identical in all the organomineral horizons of the soils and varied greatly by the seasons. In the anthropogenically disturbed soils, the share of corynebacteria, which are resistant to stress and capable of the destruction of xenobiotics, decreased.
