Hexavalent 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 کاملIsolation of chromium resistant Bacillus sp. MRKV and reduction of hexavalent chromium potassium dichromate
The ability of Bacillus sp. MRKV isolated from tannery effluent which shows resistant towards hexavalent chromium potassium dichromate (K2Cr2O7) was evaluated in this study. The bacterial strain was assayed for its reducing ability towards K2Cr2O7. The study revealed that the isolated strain has the ability to reduce the hexavalent chromium and the optimal conditions required for the chromium r...
متن کاملA Study on removal of chromium from tannery effluent treatment of chrome tanning waste water using tannery solid waste
This study illustrates the process of removal of chromium from chrome tanning waste-water by fly ash which was drive from chrome shaving dust. This experiment was carried out in a batch process with laboratory prepared adsorbent samples and chrome tanning water collected from local tanneries. The influence of various factors likes adsorbent doses, contact time, and initial concentration of chro...
متن کاملChromium Removal by Using Chosen Pseudomonads
Tannery effluent is a major source of aquatic pollution in India. Hexavalent chromium compounds are being used in a wide variety of commercial processes and unregulated disposal of the chromium containing effluent has led to the contamination of soil, sediment, surface and ground waters. In trace amounts, chromium is considered an essential nutrient for numerous organisms, but at higher level, ...
متن کاملCharacterization of tannery effluents of Hazaribagh area, Dhaka, Bangladesh
The present investigation characterizes tannery effluents by determining water quality parameters and some selected trace metallic constituents in order to measure the magnitude of environmental pollution. Effluents and sediments have also been used to isolate chromium-resistant bacteria, collected from Hazaribagh area, Dhaka, claimed to be increasing Cr (VI)-enriched environments, and utilized...
