Project summary

The main objectives of suggested project imply: investigation of biodestruction of underground communications (pipelines, reservoirs and etc.) and technical means; Reveal local aggressive strains of microorganisms responsible for biodestruction; Work up effective methods for protection of pipe insulation cover and pipeline components from destructive activity of microorganisms; Creation of optimal laboratory conditions for cultivation of aggressive strains of microorganisms.

It has long been stated that biodegradation touches almost every branch of industry. Microorganisms greatly damage not only the surface of materials, but also the internal structure and physical-chemical properties of materials thus declining their technological value. Total actual cost of damages caused by microbial degradation is billion of dollars.

The results of proposed project, if implemented will dramatically cut down the expenses related to the elimination of after-effects of microbial deterioration of industrial materials(replacement, prevention, maintenance). At the same time, obtained results could be used for environmental bioremediation.

The development of the above project is important in terms of putting in place pipeline protection and maintenance strategies. Accomplishment of project will provide the novel data and findings for avoiding the slow processes of pipes wearing and tearing, which in years may lead to damage of pipelines polymer cover and cause the corrosion of pipelines system components.

The results of the study may become important for the time when the BTC "main exporting pipeline Baku-Tbilisi-Cheyhan" will be transferred for operation to Georgian company. The accomplishment of the project will enable to determine the effect of local strains of microorganisms on the pipeline construction materials that is important for ecologically sensitive pipeline areas of the pipeline route.

Thus, the presented project suggests:

1. Revealing species of microorganisms-biodestructors residing in researched zone;
2. Evaluation of ability of microorganisms to colonize testing materials;
3. Define the degree and the character of structural changes of materials caused by microorganisms;
4. Elaborate conditions for the regulation of destructive activity of microorganisms;

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

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

The final results of the project will be:

  • Reveal the most aggressive strains of microorganisms colonizing testing materials;
  • Carrying out comparative analysis of active metabolites of aggressive strains;
  • Determination of aging factor;
  • Working up methods for lessening -decreasing destructive activity of microorganisms.

Collaborators agree to:
  • Carry out joint scientific research;
  • Exchange the information on the project results;
  • Discuss the results or research;
  • Jointly submit the data for publication;
  • Exchange visits.
