Study of Microorganisms on Polymer Composite Materials in Frigid Climate Conditions

Abstract

The paper presents research findings on extraction and identification of bacterial and mycelial forms of microorganisms on polymer composite materials under the influence of extreme frigid climate for further study of the destruction of these materials. The study made it possible to take wipe samples and scrapes from basalt plastic fittings, basalt-and fiberglass plastic on open stands in frigid climate, as well as basalt plastic pipes used for water disposal in the Arctic zone of Yakutia. The following fungal species were identified from microorganisms-destructors of polymer composite materials via biochemical tests: Aspergillus fumigatus, Aspergillus niger, Aspergillus albus, Trichoderma viridans, Penicillium sp., Fusarium roseum. At least two species of spore-forming bacillary strains Bacillus atropheus and Bacillus subtilis were defined from the bacterial group.
