Abstract
Today indiscriminate and uncontrolled discharge of metal contaminated industrial effluents into the environment has become an issue of major concern. Release of heavy metal without proper treatment poses a significant threat to public health because of its persistence biomagnifications and accumulation in food chain. To reduce metal pollution problems many processes have been developed for the treatment and disposal of metal containing wastes. The major shortcomings of the conventional treatments & low efficiency at low concentration of heavy metals, expensive handling and safe disposal of toxic sludge. Microbial metal bioremediation is an efficient strategy due to its low cost, high efficiency and ecofriendly nature moreover it results in the partial or complete biotransformation of wastes to microbial biomass and stable end products. In present work, coloration, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) , turbidity, TS, TDS, TSS, Optimization of effluent and heavy metal (Nickel, Chromium) removal from electroplating industrial effluent by microorganisms such as Bacillus sp, Micrococcus sp and Microbacterium sp were studied and analysis suggested that three strains are better microbial tool for bioremediation of heavy metal. Hence possibility can be explored to remove heavy metal load, present even in low concentration, in waste water of electroplating industrial effluent by using microorganisms.
