Arsenic (As) is highly toxic, metalloid present in environment due to natural and anthropogenic sources. Arsenic III is highly toxic than Arsenic V. 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 the present work, Arsenic was detected from industrial effluents, and observed to be significantly higher than WHO limits where Dye industrial effluent showed highest Arsenic concentration of 249 ppm. Arsenic bioremediating bacteria were isolated from these effluents and identified as Klebsiella pneumonae Isolate-II, Lysinibacillus fusiformis Isolate I and III and Bacillus subtilis Isolate-IV. The cultures were subjected to bioremediation and highest removal was found to be 80% by isolate III.
The effluents were also subjected to biosorption and phytoremediation. Highest biosorption rate was found to be 47.2% by isolate II within 48 hours of incubation. Consortium of Klebsiella pneumonae+Pseudomonas putida showed 92.8% degradation and Lysinibacillus fusiformis+Bacillus subtilis showed 94% degradation within 4 days. This work will help us in careful handling of issues like Arsenic pollution, over exploitation of natural resources and sustainable development.
