Hexavalent chromium reduction by bacteria from tannery effluent.
Chromium is generated from several industrial processes. It occurs in different oxidation states, but Cr(III) and Cr(VI) are the most common ones. Cr(VI) is a toxic, soluble environmental contaminant. Some bacteria are able to reduce hexavalent chromium to the insoluble and less toxic Cr(III), and thus chromate bioremediation is of considerable interest. An indigenous chromium-reducing bacteria...
متن کاملHexavalent chromium reduction by chromate-resistant haloalkaliphilic Halomonas sp. M-Cr newly isolated from tannery effluent
The current study aimed to isolate and characterize a chromate-resistant bacterium from tannery effluent, able to reduce Cr(VI) aerobically at high pH and salinity. Environmental contamination by hexavalent chromium, Cr(VI), presents a serious public health problem. Enrichment led to the isolation of 12 bacteria displaying different degrees of chromate reduction. Phenotypic characterization and...
متن کاملStudies on Chromate Removal by Chromium-Resistant Bacillus sp. Isolated from Tannery Effluent
A chromate-removing strain was isolated from spent chrome effluent and identified as Bacillus circulans strain MN1. The isolated strain was studied for resistance to Cr (VI) and its ability to remove Cr (VI). The strain was found to tolerate Cr (VI) concentration as high as 4500 mg/L, but the cells growth was heavily influenced when initial Cr (VI) concentration was increased between 1110 mg/L ...
متن کاملOccurrence of chromium resistant thermotolerant coliforms in tannery effluent.
Twenty six thermotolerant strains resistant to high levels of chromium (50-250 microg/ml) were isolated from treated tannery effluent. They were also found resistant to multiple heavy metals and antibiotics. Majority of them were resistant to copper and bacitracin. Nine strains representing different resistance patterns were selected for plasmid profile and conjugation studies. Agarose gel elec...
متن کاملBiodegradation potential of bacterial isolates from tannery effluent with special reference to hexavalent chromium
The application of isolated bacterial culture as biological tool for hexavalent chromium removal from tannery industry waste water was investigated. A number of bacteria tolerant to high levels of chromate (>400μgml) were isolated from tannery effluents. These isolates showed varying degree of Cr (VI) reduction under oxic and anoxic conditions at room temperature. Ten isolates were found to be ...
