Abstract :

 Hexavalent chromium (VI) is particularly worrying because of it’s widespread contamination of soil, water 

and produce toxic influence on human health. The main objective of the study is to reduce toxic chromium (VI) to nontoxic chromium (III) by bacteria from halophilic alkaline Lonar Lake, situated in Buldhana District of Maharashtra State, India. In these studies, water and sediment samples were collected from Lonar Lake and inoculated in 
Nutrient oth containing K2Cr2O7 (100µg/mL). The potential chromium reducing bacterial strain (DHT14) was isolated 
from Lonar Lake and characterized through cultural, morphological, biochemical characterization and identified by 16S 
rRNA gene analysis as Lysinibacillus mangiferihumi. The chromium reducing efficiency of the L. mangiferihumi was 
estimated to be 84% in 96 hrs. Results of this study showed that, the L. mangiferihumi found to be highly efficient 
chromium reducer and could use for detoxification on polluted sites.
