Abstract – This work was planned to identify the microbes which are effective for the biological degradation of dairy wastewater. The activated sludge process facilitates the removal of carbonaceous BOD and the stabilization of organic matter by a variety of microorganisms (principally bacteria). Bacillus supergene is one of the predominant bacteria found in dairy waste water. The bacteria Bacillus .sp was isolated from the dairy wastewater and inoculated into the samples taken from the dairy industry. Laboratory tests were carried out by inoculating varied cell concentrations and incubating under aerobic conditions to determine the removal of COD and protein from the samples. During the incubation, microbial growth was monitored by the measurement of optical density. The biodegradation ability of the native bacteria was also compared with the commercial inoculum of the same isolate. The COD removal was higher for the commercial inoculums and the protein removal was higher in the selected native strain.
