Ecological Structure of Public Transport Microbiocoenosis

indices (Shannon’s species diversity index, Simpson’s index of dominance, Margalef’s species richness index, and Pielou’s species evenness index) showed that an increase in the specific diversity of microbial communities is accompanied by a regular decrease in dominance and an increase in evenness. Analysis of the group of dominant species identified in the buses of the three route groups revealed that the species similarity of the dominant species, estimated by the value of Koch’s index, was only 0.14, which could be explained by the presence of only one common species ( Acinetobacter lwoffii) . Studies of the microbial community of urban transport present a perspective for solving the sanitary, hygienic and environmental aspects of the integrated problem of ensuring the ecological safety of the urban environment.
