BACTERIAL REDUCTION OF CHROMATE. APPLICATION OF NEW STRAINS IN THE BIOREMEDIATION SYSTEMS

This paper presents the results of a study of a new chromate-reducing strain of the bacterium genus Salisediminibacterium MB1000 isolated from sediments of salt alkaline lakes of the Kulunda steppe (Altai, Russia). Optimal conditions for growth and chromate reduction have been determined depending on temperature, pH of the medium, salinity and salt ratio. The possibility to scale up the chromate reduction process in a laboratory bioreactor is shown. The average speed of the chromate reduction process is calculated.
