The article is devoted to the study of the variability of the biochemical activity of the bacilli under the influence of chemical waste. The obtained results describe their state when this treatment.

The resistance of polymer composite materials to external environments including fungi, bacteria and yeasts is a key factor in their reliability. These microorganisms, known as degraders or biodegraders, are capable of causing biological damage and even complete destruction of composite materials by altering their structure and functional characteristics.

The article deals with the actual problem of breeding industrial microorganisms to achieve environmental goals. Various methods of selection and improvement of microorganisms are discussed, as well as their application in biodegradation, bioremediation, biosynthesis, biogeochemical cycle and application in industry and construction to combat bio-damage of polymer composite materials and structures based on them. The article discusses the challenges and prospects of this field of research. The authors consider the factors influencing the efficiency and safety of the use of industrial microorganisms for environmental purposes. This article provides an overview of important topics and is a valuable source material for researchers and specialists interested in developing environmentally sustainable solutions based on industrial microorganisms.

It is relevant in the field of PCM research to study the influence of Arctic climatic conditions characterized by high temperature difference, humidity and intense solar radiation in the summer season on their properties. Also, a relevant task is to study the influence of bio-infestation on the structure and strength of PCM, since microorganisms use the binder composition as a source of life support. The paper presents comparisons of bending and tensile strength of hybrid PCMs, as well as their open porosity, after 1 year of natural exposure and samples exposed for 12 months, with preliminary biocontamination.
