Аннотация: Modern molecular genetic methods have provided a extended opportunities for studying the frequency taxonomic composition of soil microbial communities, including uncultivated strains of microorganisms. Modern spectrum analysis of operational taxonomic units (OTU) identified by 16Sr RNA gene is limited to the comparison of the nucleotide sequences. We propose to use a fractal model to describe the frequency spectrum of microorganisms. This model necessary to study the network self-organization of microbial communities and the functional diversity of the processes of biological systems. The power series from three frequencies of OTU are the fractal model of frequencies spectrum of OTU (for example: 0.1, 0.01, 0.001). Because there are many OTU’s peaks in the original spectrum, peaks grouped with the same or similar amplitudes to form OTU-groups. Fractal topological analysis of the location of OTU-groups on a fractal portrait of the microbial community was been used to search for degenerate triangles with OTU-groups at the vertices, since these OTU-groups correspond to a microbial biosystem and to fractal model for the grouped OTU’s frequencies. The functional diversity index (IFD) of biochemical processes is been determined by number of OTU-groups in microbial community and by number of OTU-groups in biosystem. The IFDdynamics was been calculated with using the daily data of molecular-genetic analysis of soil samples. As a result, we revealed the periodic fluctuations in IFDvalues and the periodic replacing of OTU-groups in a soil microbial biosystems that provide a wide diversity of a biochemical processes in soil microbial communities.
