Project summaryThe project is devoted to the development of new-generation bioorganic preparations – oil-degraders, which can be used for remediation and recovery of oil-contaminated soils. It is expedient to obtain such preparations by immobilization of oil-destructing microorganisms cells on organic carriers represented by microbial association grown on organic wastes under aerobic conditions. This allows achieving multifunctional action of the preparations proved by the ability not only to degrade oil contaminations, but also to increase biological activity of soils, to provide positive balance of humus, to activate soil microflora with favorable effect on plant rhizosphere, to provide adaptation of alkanotrophic microflora and to reduce the stress for microorganisms in the contaminated environment.
The goal of work is development and testing a complex preparation of immobilized microorganisms-oil destructors on multifunctional carriers of new type for remediation and recovery of oil-contaminated soils.
As biological substrates pilot batches of the following bio-fertilizers will be taken:
- «Bamil» – based on the microbial association cultivated on pig farm sewers;
- «Omug» – based on microbial association cultivated during aerobic fermentation of chicken manure;
- «Biohumus» – product of worm composting of different organic wastes by specially bred earthworm species.
For control, peat will be used.
For “Bamil” fertilizer production method SU patent # 1757209, December 25 1992, was issued (the patent-holder is Arkhipchenko I. A., the Project Submanager). For “Omug” bio-fertilizer an application for invention #2005101367/13, January 21 2005 was submitted; the author – Arkhipchenko I. A. et al. “Biohumus” fertilizer production method is also patented, RF patent #2125549, December 29 1997(the patent-holder is SFES RCT&HRB of FMBA of RF).
New biopreparations are expected to be capable of recovering soils even at low-temperature areas. These biopreparations can be used not only on vast territories, but also on small areas contaminated with oil products, e.g., parking places and gas stations.
The team of researchers – the project participants includes microbiologists, biochemists, ecologists, and biotechnologists experienced in the development of novel fertilizers and biopreparations for increasing biological activity of soils and their recovery. Considerable experience of the project participants – experts in the field of agricultural organic wastes bioconversion and development of the technologies for producing new effective microbial fertilizers is reflected in patents, as well as normative and technical documentation, certificates on deposited microbial strains, and scientific publications in Russian and foreign journals.
