ISOLATION AND IDENTIFICATION OF MICROBIAL STRAINS INVOLVED IN INDUSTRIAL SYSTEMS MATERIALS CORROSION IN AQUATIC ENVIRONMENT

摘要

The accumulation of microorganisms and metabolic products on metal surfaces contributes to the corrosion process, which reduces the lifetime of industrial materials. Corrosion is rarely related to a single mechanism or to one species of microorganisms. The experimental investigation has been done with the aim to identify the bacterial community grown on metallic surfaces of industrial aggregates immersed in aquatic environment. The isolation and identification procedure finally provided four predominant bacterial strains as Pseudomonas koreensis, Pseudoxanthomonas mexicana, Brevibacillus parabrevis and Bacillus pseudomycoides.
