Arsenic (As) is highly toxic, heavy metal present in environment due to natural and anthropogenic sources. Arsenic III is more toxic than Arsenic V. Ingestion of Arsenic III leads to increased risks of cancer, gastrointestinal symptoms and disturbances of cardiovascular, lungs, bladder and kidney and environmental pollution. Arsenic removal by biological means is an upcoming and eco-friendly technique where microorganisms have the ability to detoxify heavy metals from the environment. In this work, arsenic was detected from industrial effluents and was found to be significantly higher than WHO limits. Textile dye effluent showed highest arsenic concentration of 249 ppm. From these effluents, arsenic degrading bacteria were isolated and identified as Klebsiella pneumonae, Lysinibacillus fusiformis and Bacillus subtilis. The respective cultures were subjected to bioremediation and highest oxidation was found to be 80%. The effluents were also subjected to biosorption and phytoremediation. Highest biosorption rate was found to be 47.2% by chrome plating effluent isolate within 48 hours of incubation. Consortium of Klebsiella pneumoniae: Pseudomana putida showed 92.8% and Lysinibacillus fusiformis: Bacillus subtilis showed 94% degradation within 4 days. The dye isolate was subjected to synthesis of arsenic nanoparticle which could be exploited for drug delivery. All isolates showed the ability to produce siderophres. This work will help us in careful handling of issues like pollution, over exploitation of natural resources and sustainable development.
