Detoxication of toxic chromate at fermentation of ecologically dangerous food waste using soil microorganisms

Abstract

Goal. Determine the quantitative indices of the stability of the natural microbial grouping to chromate anion and the ability to restore it to Sr (III). Methods. Periodic cultivation, gas chromatographic and photocolorimetric analyzes. Results The microbial association effectively destroys waste, reducing its mass by 6 times in 9 - 12 days. The metabolically active association quickly and efficiently restores chromosomes. An increase in the concentration of chromates leads to an increase in the time of their recovery. Conclusions. The obtained data can be used to create the latest nature conservation biotechnologies and predict natural remediation of the environment contaminated with chromates.
