The presence of sulfate-reducing bacteria results in a reduction of the protective properties of polyvinyl chloride (PVC) film coatings. The authors examine the effect of other types of soil microorganisms. Investigations were carried out with the cultures of bacteria Pseudomonas fluorescens B-22 and fungus Aspergillus niger van Tieghem F-1119 which are almost always present in corrosion regions in the routes of transmission pipelines. The microorganisms were grown in a mineral medium with glucose (Ps. fluorescens) and sucrose (A. niger).
