Two chromium-resistant bacterial strains, CrT-1 and CrT-13, tolerant up to 40mg K2CrO4 ml−1 on nutrient agar, 25mgml−1 in nutrient broth, and up to 10mgml−1 in acetate-minimal media, were identified as Ochrobactrum intermedium and Brevibacterium sp., respectively, on the basis of 16S rRNA gene sequencing. Uptake of chromate was greater in living cells than in heat-killed on dried cells. CrT-1 reduced 82%, 28% and 16% of Cr(VI) at 100, 500, and 1000μgml−1 after 24h while CrT-13 reduced 41%, 14… CONTINUE READING
