Many industry such as the electroplating & mining companies produced large amount of waste water that contain hazardous amount of mercury, lead, cadmium, silver, copper & zinc ions. The search for new technology involving the removal of toxic metal from waste water has directed attention to biosorption which can be defined as the ability of biological material to accumulate heavy metal from physico-chemical pathway of uptake. The topic under interest is Bioaccumulation of heavy metal by using bacterial isolates obtain from Zn containing waste. Study gives focus on Isolation of Zinc Bioaccumulating bacteria from Zinc containing waste from Electroplating industry. Total four Zn accumulating bacteria were isolated and studied for their Morphological, Cultural and enzymatic Characters. The isolated bacterial species are from Genus Plesiomonas, Psedomona and Staphylococci .Analysis of Bioaccumulation with Atomic Absorption Spectroscopy showed that among all isolates Psedomonas has maximum Bioaccumulation capacity and has highest MTC against Zn as Compared to other genera. This study leads to the conclusion that, Psedomonas is an efficient organism for Zn bioaccumulation.
