“…Biological methods, such as bioreduction, bio-accumulation or biosorption using microorganisms, have been examined for their chromium removal abilities [15][16][17] and these methods offer potential alternatives to existing technologies of Cr(VI) removal. Until now, most Cr(VI) removal by microbes was obtained using pure culture techniques under either anaerobic or aerobic conditions depending on the species [18][19][20][21][22][23]. Under anaerobic conditions, both abiotic and biotic reduction mechanisms are competitive (over time, pH may increase due to the mineralization of organic matter to CO 2 , which increases HCO 3 -concentration, or owing to an acid-consuming redox reaction).…”

“…41 Thus, biotreatment methods are widely studied for Cr(VI) remediation. [3][4][5][6][7][8][9][10]40 It was reported that the tannery, electroplating and metal-based industry wastewaters (pH 2.0−8.3) generally contained 14.16−534 mg L −1 Cr, 4.2−13.7 mg L −1 Fe(III), and 19.8 mg L −1 SO 4 2− . 3,42,43 If traditional biotreatments were used, Fe(III) and SO 4 2− can be reduced by iron and sulfate-reducing bacteria, respectively, and then the formed Fe(II) and sulfide reduce Cr(VI).…”

“…10 The Cr(VI) reduction rate generally ranged from 0.24 to 2.22 mg Cr(VI) L −1 h −1 . 3,5 In the present study, the newly isolated strain Acinetobacter sp. HK-1 was capable of simultaneously reducing Cr(VI) (1.64 mg Cr(VI) L −1 h −1 at an initial concentration of 55 mg L −1 ) to Cr(III) and immobilizing Cr(III) under anaerobic conditions.…”
