Summary: Cyanobacteria constantly exist in the soil and ground complexes of phototrophic microorganisms in urban soils. In soil "blooming" , including the phenomenon of the winter "blooming", it is this group of organisms that dominates in terrestrial growth in different areas of the city (industrial, transport, residential, park areas), leaving the representatives of eukaryotic algae in the minor position. Сyanobacteria are characterized by rather wide species diversity, with the predominance of non-heterocystic forms as well as high-density of populations (up to tens of million cells per 1 cm2). Cyanophytization of phototrophic microbial complexes is a characteristic feature of urban soils.
