Determination of minimum inhibitory concentration of cadmium salts on the microbial strains isolated from Buriganga River-bed soil

Abstract

Heavy metals are abundantly available in our environment. Most of them are toxic in high concentration. One of those heavy metals is Cadmium which is released from tannery, dye, chemical industries in broad range and spreading toxicity to the environment and to the living organisms. Bioremediation is a process by which it is possible to reduce heavy metals from the environment using micro-organisms. Heavy metal resistant bacterial strains are the best choice of micro-organisms in this bio-remediation process. In this study we have worked with 14 different types of Chromium resistant bacteria and analyzed their resistance capacity towards Cadmium. The purpose of this study was to find multiple heavy metal resistant bacterial strains that can be used to remove heavy metals from environment for the betterment of the human beings as well as for all the other living organisms.
