AI Article Synopsis
- Researchers studied Acinetobacter junii VITSUKMW2 from a chromite mine for its ability to remove Cr(VI) and enhanced this capacity using statistical design techniques.
- The study evaluated the removal efficiency under varying pH levels (5-11) and temperatures (30-40°C) with different carbon and nitrogen sources.
- The optimal conditions for Cr(VI) removal were identified as 14.85 g/l molasses, 4.72 g/l yeast extract, and 54 mg/l Cr(VI), achieving 99.95% removal in 12 hours, indicating the bacterium's high potential for bioremediation.
Article Abstract
The Cr(VI) removal capability of Acinetobacter junii VITSUKMW2 isolated from the Sukinda chromite mine site was evaluated and enhanced using statistical design techniques. The removal capacity was evaluated at different pH values (5-11) and temperatures (30-40 degrees C) and with various carbon and nitrogen sources. Plackett- Burman design was used to select the operational parameters for bioremediation of Cr(VI). Three parameters (molasses, yeast extract, and Cr(VI) concentration) were chosen for further optimization using central composite design. The optimal combination of parameters was found to be 14.85 g/l molasses, 4.72 g/l yeast extract, and 54 mg/l initial Cr(VI), with 99.95% removal of Cr(VI) in 12 h. A. junii VITSUKMW2 was shown to have significant potential for removal of Cr(VI).
