Dissemination of corrosive-aggressive bacteria in soils from different biotopes under man-caused load was investigated. In the man-caused biotopes there were 2–3 degree more of the sulfate-reducing bacteria, 1–2 degreeless nitrogen-fixing bacteria, and 2–3 degreeless denitrifying bacteria, than in the innate biotopes. The man-made and innate soils did not differ significant in the amount of the iron-reducing bacteria, sulfur bacteria, and ammonifyingly bacteria. Microbial communities from man-caused soils are produced 1.5–2.5 times more hydrogen sulfide than the innate ones. Man-caused invasion to the soils is a stress situation for microbial community, when the ecological trophic groups of bacteria are altered and activity of the corrosive aggressive sulfate-reducing bacteria is increased.
