ABSTRACT: A comparative study was undertaken using different strains of bacteria to obtain the highest percent removal of Cr6+ from tannery waste. Bioremediation of chromate waste with one or more metal tolerant bacteria is a potential method of releasing chromium from tannery waste. Sampling from tanneries resulted in the isolation of five bacteria with the capability of releasing chromium from tannery waste. The isolates represent five species of three different genera of soil inhabiting bacteria. Two isolates ES 29-Bacillus and ES 32-Arthrobactor crystallopoites were able to release (98.2%) and (98.6%) of the chromium respectively, which is the most difficult component of chromate waste to remove from effluent. Importance has been given to these study due to chromium is generally toxic to many non-target organisms. These pollutants that get release from various industrial wastes also pollute the aquatic environment and it leads to many changes in organismal physiology.
