THE SYNTHESIS OF PHYTOHORMONES BY SOIL MICROORGANISMS-DESTRUCTORS OF ORGANOCHLORINES
Journal Title: Мікробіологія і біотехнологія - Year 2016, Vol 0, Issue 4
Abstract
Organochlorine pesticides inhibit the plant growth in the pollution soils. The application of microorganisms-destructors synthesizing plant hormones is promising to bioremediation, but is little studied. aim. To reasearch the ability of effective strain-destructors of hexachlorocyclohexane (HCH) for synthesing phytohormonal compounds to stimulate the plant growth in the contaminated areas. methods. Microbiological, chromatographic, statistical research methods. results. Soil microorganisms-destructors of organochlorines Pseudomonas putida IMV B-7289, P. putida UKM B-398, Bacillus megaterium IMV B-7287, Stenotrophomonas maltophilia IMV B-7288 have synthesized and have produced in the nutrient medium a wide spectrum of plant hormones: cytokinin, auxin, gibberellic and abscisic acid. The qualitative and quantitative composition of the plant hormones synthesized by microorganisms of strains is characterized by differences among the studied strains. P. putida UKM B-398 is the most active producer of extracellular gibberellic acid, auxin and cytokinin. Conclusions. The strain P. putida UCM B-398 is interesting as a promising microbial component of biopreparation and may be used in combination with effective destructors of HCH B. megaterium IMV B-7287, and P. putida IMV B-7289.
