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

Abstract

The presence of heavy metal in the environment is currently increasing in amount especially in soil and water due to their frequent use. Most of the heavy metals are harmful and toxic. One of the heavy metals is Chromium which is abundantly found in mining, tannery, dye industries. The usage of different techniques in removal of heavy metal have increased due to its exposure. Minimum In this experiment, 14 different bacterial strains were used against different chromium concentration analyzed their resistance capacity towards Chromium. Bacterial growth was first observed in media and their minimum inhibitory concentration were measured in chromium concentrated environment. Minimum inhibitory concentration is the lowest concentration of an anti-microbial that resist the growth of a microorganism. The purpose of the study was to identify heavy metal resistant bacterial strains by the minimum inhibitory concentration test.
