Investigation of bacteriocenose of periphytone of stone substrates of the lithoral zone of the Kolskaya gulf

Quantitative characteristics of the heterotrophic bacterium community of periphyton of stony substrates in a natural sample and in a laboratory experiment were studied. The experiment consisted in studying the temporal dynamics of fouling of sterile stony substrates in sea water, selected at the station under study, together with substrates, under conditions close to natural ones.
