Project summary

The main objectives of suggested project imply: study of biodegradation of materials (metals and alloys of metals, and polymers) by microorganisms. Reveal local aggressive species of microorganisms responsible for biodegradation. Work up methods for prevention of materials from destructive activities of microorganisms. Experimental study of conditions revealing/promoting optimal destructive activities of aggressive strains of microorganisms and their possible use in bioutilization of industrial wastes.

It has been stated that biodegradation touches almost every branch of industry. Microorganisms greatly damage not only the surface f materials, but also the internal structure and physicochemical properties of materials thus declining their technological value. Microorganisms, by multienzymatic systems conduct chemical transformations of complex substances which are inaccessible to other organisms.

Total actual cost of damages caused by microbial biodegradation is billions of dollars. The results of proposed if implemented will dramatically cut down the expenses related to biodegradation of industrial materials (replacement, prevention and maintenance). At the same time this results could be used in utilization of industrial wastes.

Thus, the presented project suggest:

– Evaluation of ability of microorganisms to colonize tested materials under identified conditions.

– Revealing of new, aggressive strains of fungi.
– Define the character of structural changes of materials caused by microbial degradation.
– Elaborate the optimal conditions for vital activity of experimental microorganisms.

The project will be realized at Department of Cellular and Molecular Biology, Microbiology, Virology; Tbilisi State University.

The project should be referred to the category of applied science.

The final results of the research will be:

– new local super aggressive strains of microorganisms;

– optimal conditions for captivation of this strains;
– recommendations to decrease the biodegradation;
– conditions for microbiological utilization of industrial wastes;

Collaborators agree to:

– carry out joint scientific research;

– exchange the information on the project results;
– discuss the results of research;
– jointly submit the data for publication;
– exchange visits.
