Screening of Heavy Metal Resistant Bacteria from Nale Lake of Vasai Taluka of Maharashtra
Keywords:
Heavy metals, Bioaccumulators, Vasai Taluka, Nale LakeAbstract
Due to rapid industrial progress and urbanization environmental pollution with toxic heavy metal has become one of the major concerns in today’s world. We need advance chemical and mechanical technology for removal of heavy metals from polluted water, but this technology is quite expensive. Microbial technologies and inventions may provide an alternative to the current methods. Microorganisms and microbial products can be highly efficient bioaccumulators for heavy metals. In this study, preliminary investigation showed presence of few heavy metal resistant bacteria from a lake of Vasai Taluka situated in Nale village. Different isolates showed different degree of resistance to Arsenic, Lead and Cadmium proving that they can be used as tools for remediating the water contaminated with these toxic heavy metals. Further investigations need to be carried out to identify and characterize the isolates so as to establish their role as bioaccumulators.
