Abstract

Reduction of Cr(VI) compounds by the immobilized cells of sulfate-reducing bacteria Desulfomicrobium sp. CrR3

Highlights

Immobilized bacterial cells are increasingly used to purify the environment from both organic and inorganic pollutants
CrR3 cells is the promising way of water purification from hexavalent chromium compounds
CrR3 bacteria depend on the initial hexavalent chromium content and cell concentration

Summary

INTRODUCTION

Immobilized bacterial cells are increasingly used to purify the environment from both organic and inorganic pollutants. Compared to the traditional methods of biological purification of wastewater in aerated lagoons, immobilized microbiota has a number of advantages. Such an “immobilized catalyzer” of the purification process is easy to remove from the reaction medium, which enables termination of the process at the right moment, while removal of active sludge from an aerated lagoon involves a long process of sedimentation and centrifugation. Using the immobilized active sludge makes it possible to purify wastewater continuously and regulate the purification process by changing the flow velocity. We made an attempt to immobilize sulfate-reducing bacteria in order to use them for water purification from toxic compounds of hexavalent chromium
