On the advantages of the heterogeneity of microbial aggregates in biotechnologies for wastewater treatment
It is shown that the implementation of modern trends towards the creation of effective water treatment systems is based on technologies that use the heterogeneity and stratification of aggregated microbial communities. Based on the results of the analysis of our own experimental studies, as well as the work of other authors, it was concluded that effective biological treatment of wastewater with complex removal of impurities is determined by the total development of individual groups of microorganisms using different substrates and often requiring fundamentally different conditions of cultivation in one structure. The results of the analysis of information on the spatial distribution of autotrophic and heterotrophic microorganisms, aerobes, microaerophils and obligate anaerobes in situ within the single microbiocenosis of the biological purification system, as well as the metabolic activity of the microorganisms of the biocenosis under conditions of their ex situ cultivation on selective media indicate a significant potential of heterogeneous microbial aggregates for use in biotechnology wastewater.
