ИЗУЧЕНИЕ АДГЕЗИОННОЙ СПОСОБНОСТИ КЛЕТОК БАКТЕРИИ A.FERROOXIDANS НА ПОВЕРХНОСТИ РУДНЫХ ТЕЛ МЕСТОРОЖДЕНИЯ ШОКПАР

Abstract

The behavior and the possibility of attachment of A. ferrooxidans strain cells to the sulfide-gold-bearing ore of the Shokpar deposit and the influence of ore particles on bacterial strains were investigated. The previous stages were carried out before the adsorption process and further for the bioleaching process, such as culturing of microorganisms Acid.ferrooxidans, granulometric analysis of ore composition from the Shokpar deposit. According to the amount of data from the study, the process of immobilization directly depends on the time that an experiment was set. Also, according to the quantitative indicators of cells from 3 strains of A. ferrooxidans, taken as an adsorbate, it was determined that 1 strain of Acid.ferrooxidans completely went into an inactive state during the 12-hour exposure time, and according to the data, this strain of bacteria turned out to be more suitable for ore particles with increases in biomass.
