Biotransformation of chromium (Cr-VI to Cr III) from tannery effluent using bacteria and fungi
Chromium, a priority pollutant is well known for its mutagenicity, carcinogenicity and teratogenicity in humans, animals and plants. Extensive use of chromium in industries such as leather tanning, stainless-steel production, electroplating and wood preservatives have resulted in extensive chromium contaminated soil and ground water. Microorganisms are involved in the removal of toxic wastes, b...
متن کاملBiosorption and biotransformation of Cr (VI) by hexavalent chromium-stressed environmental fungal isolates from wastewater
As conventional physico-chemical heavy-metal remediation technologies like ion-exchange, reverse osmosis, electrodialysis etc. are becoming extremely expensive, the possibility of use of microorganisms in bioremediation or biorecovery of different heavy metals from industrial effluents is extensively explored by different workers. Hexavalent chromium stressed environmental fungal isolates from ...
متن کاملOptimization of Cr(vi) Biotransformation by Response Surface Methodology Using Microbacterium Maritypicum
In the present study, a novel indigenous bacterium was isolated from the effluent of Electroplating industry having capability of biotransforming Cr(VI) ions into Cr(III) ions. Morphological, Physiological and biochemical characterization of the bacterial strain was carried out and later sequence analysis of 16S rRNA gene of the strain identified it as Microbacterium maritypicum. By utilizing t...
متن کاملGrowth Improvements of Sunflower Seedlings by Cr(VI)-Resistant Bacteria
In the present study, three chromium resistant bacterial strains (CrT-1, CrT-2, CrT-3) which could resist veryhigh concentration of K2CrO4 (up to 40 mg ml-1 on nutrient agar plates and 10 mg ml-1 in acetate-minimalmedium) were used to inoculate the sunflower seeds both as control and under chromium stress. Cr(VI)caused severe reduction in different growth parameters (seedling ...
متن کاملRESPONSE SURFACE METHODOLOGY FOR BIOTRANSFORMATION OF Cr ( VI ) USING Salmonella sp . S 4
The present study was an attempt to explore the efficiency of indigenous bacterium isolated from the effluent of Electroplating Industry in transforming hexavalent chromium into trivalent chromium. The isolated bacterium was characterized on the basis of its morphological, biochemical and physiological properties as Salmonella sp.S4. Response Surface Methodology (RSM) based on a three-level thr...
