CURRENT RESEARCH TOPICS:

     

• Physiology, biochemistry, biosynthesis and identification of primary and secondary metabolites of actinomycetes and filamentous fungi. Research is focused on: taxonomy, physiology, biochemistry and biosynthesis of enzymes and Optimization of cultivation conditions for extracellular hydrolytic enzymes and other biologically active substances from free and immobilized cells. Characteristics of the obtained enzyme preparations and investigation of the possibilities for their application.

• Investigation on physiological response of microorganisms to different pollution: heavy metals, phenol, oil products.

• Bioremediation of different xenobiotics by free and immobilized cells.

• Detoxification of aquatic ecosystems, contaminated by heavy metals and phenol derivatives.

• Development of variants of technologies for microbial synthesis of amino acids (lysine, valine, leycin), depending on the sources of the raw material.

• Creation of an unique technological scheme for the purification of CO2 from biogas based on the use of microalgae in high-efficiency photobioreactors. Microalgal cultivation scheme has been developed to multiply the use of their biomass both for energy purposes and for the production of valuable biologically active substances. A new original strategy for modeling, optimization and scaling of column photobiorectors has been developed.
