Abstract

The aim of this research was to study the development of various associations of microorganisms in wastewaters and soil near wastewater treatment plant. It was found that the development of some groups of microorganisms is suppressed. Dozens of heterotrophic bacteria cells were found in the soils and wastewater. Evaluation of the seasonal dynamics of bacteria number during the year in the wastewater demonstrated the persistent microcenosis with denitrifiers, ammonifiers, both non-spore and spore-forming oligonitrophils, fungi and yeast present. The growth rate of bacteria was determined. It is shown that the microbial communities (bacteria, actinomycetes, fungi) present in the studied ecological niches gradually oxidize toxic compounds.
