Studies on bioreduction of cr vi using environmentally significant microorganisms

Abstract

Cr VI bioreduction was studied with fungi and bacteria Initially Phanerochaete chrysosporium a white rot fungi was tested for bioreduction of Cr VI P chrysosporium successfully reduced 10 mg L 1 of Cr VI at pH 6 in 160 h In order to ease the separation of cells P chrysosporium was entrapped in Ca alginate and three other matrices A maximum of 98 5 reduction of Cr VI at an initial Cr VI concentration of 10 mg L 1 was obtained with Ca alginate immobilized cells at pH 5 Cr VI reducti
