DECOMPOSITION OF PHOSPHORUS-CONTAINING COMPOUNDS IN AQUEOUS AND POLYSACCHARIDE SOLUTIONS OF ORGANIC ACIDS

The purpose was to study the patterns of dissolution (solubilization) phosphorus-containing minerals in aqueous and polysaccharide solutions organic acids order model mechanism mineral destruction by soil bacteria synthesizing exopolysaccharides. Methods. Model, laboratory-analytical, microbiological, statistical. Results. destructive effect on is manifested both solutions. introduction bacterial into an solution increases decomposition 1.34̶ 4.96 times. influence chemical structure acid molecules intensity mainly presence polysaccharide, while effectiveness action depends nature being destroyed. To maximum degree, a citric acid: molten magnesium phosphate ̶ 2.55 times, thermophosphate 2.11 flour Decomposition phosphorus compounds ascorbic oxalic enhances lesser extent than solution. Modeling under non-sterile conditions (soil conditions) made it possible establish that are subject consumption microbiota, especially acids, - succinic. Aqueous after 18 hours incubation lose their leaching activity 1.06 ̶12.1 makes avoid rapid microorganisms, because which efficiency decreasшes only 5–20% compared sterile ones. Conclusions. enables latter be transferred sorbed state, as result susceptibility microorganisms sharply reduced. Thus, polysaccharide-forming not destroy more intensively low-molecular-weight metabolites, but also synthesize stable long-term functioning complex soil.
