[Dynamics of microbial populations in the biofilm on protective coating].

Dynamics of microbial populations in the biofilm on the surface of protective coating Poliken 980-25 has been studied. It was shown that in the process of succession one can observe some changes of taxonomic composition of biofilm bacteria. Bacteria of Pseudomonas genus were revealed at early stages of succession, they reduce Fe+3 and oxidize carbohydrates. Bacteria of Arthrobacter genus begin developing 2 hours after the exposure, Bacillus genus bacteria appear 6 hours after the experiment beginning. It should be noted that iron-renewing bacteria as dominants in the biofilm are the agents ofbiolesion of not only protective material but also metal.
