SPECIES-DIVERSITY OF AN INTERTIDAL MICROBIAL COMMUNITY IN CONDITIONS OF ANTHROPOGENIC POLLUTION

The relation between the input of organic substrata of the anthropogenic derivation and the change in the species diversity and enzyme activity of an intertidal microbial community was considered. The greatest hydrolytic activity of bacteria was found in areas with high anthropogenic pressure - near ports, fish-processing and timber plants. The appearance of various pollutants in the aquatic environment caused a change of dominant species of bacteria-destructors and elimination of some members of the microbial community, which led to change in the direction of a number of microbiological processes. It is suggested that disturbance of a natural course of mineralization may tell on the state of the environmental and, finally, affect the functioning of the entire marine ecosystem.
