Microbial remediation is a technique of eradication of hazardous substances that is organic and inorganic xenobiotic substances and also heavy metals from the environment with the help of microbes. Industrializations have increased in the concentration of heavy metals that is cadmium, lead, iron, copper, chromium. The biosorption by S. natans was carried out for three different heavy metals: copper, chromium, lead. Various physical and chemical factors affect the sorption capacity by the microorganisms. The pH for the removal of heavy metals at 7.0 was Cu (48%), Pb (75%) and Cr (52%). Optimum temperature for the removal of heavy metals was at 37°C. Maximum sorption was observed, Cu (58%), Cr (60%) and Pb (82%).
