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 کاملBioremediation of toxic heavy metals using acidothermophilic autotrophes.
Investigations were carried out to isolate microbial strains from soil, mud and water samples from metallurgically polluted environment for bioremediation of toxic heavy metals. As a result of primary and secondary screening various 72 acidothermophilic autotrophic microbes were isolated and adapted for metal tolerance and biosorption potentiality. The multi-metal tolerance was developed with h...
متن کاملDetermination of Chromium in Tannery Effluent and Study of Adsorption of Cr(VI) on Sawdust and Charcoal from Sugarcane Bagasses
Spectrophotometric method using diphenylcarbazide as a colour developing reagent has been used to analyze the chromium content in tannery effluent located in Bara and Parsa districts of Nepal and Sirsiya River which is an ultimate drainage of these waste water streams. The adsorption of hexavalent chromium from aqueous solution onto formaldehyde treated sawdust and charcoal of sugarcane begasse...
متن کاملToluene/ter-butanol mixed solvent for the selective extraction of Cr(VI) from divalent heavy metals.
A solvent-extraction system comprising toluene/ter-butanol (ter-BuOH) mixed solvent as the organic phase was developed to selectively extract Cr(VI) from acidic chloride media in the presence of divalent metals, namely Cd(II), Co(II), Cu(II), Ni(II) and Zn(II) under 5 M CaCl2 salting-out conditions. Chromium(VI) was selectively extracted as a solvated ion-pair of [ter-BuOH2+ x CrO3Cl-] at ter-B...
متن کاملBioremediation of pharmaceutical industrial effluent by organisms screened from effluent discharged soil
Two bacterial strains were isolated from pharmaceutical effluents discharged soil. The samples were identified as Klebsiella pneumonia and Pseudomonas aeruginosa the biological degradation was carried on two bacterial isolates separately added to pharmaceutical effluent water. After proper interval were analysed the physic chemical parameters such as pH, Turbidity, Chemical oxygen demand (COD),...
