Dairy wastewater typically contains high concentrations of contaminants, because of the volume produced is generally substantial, the total contamination load is significant. Biological deterioration appears to be the most promising therapeutic option among the various choices. Furthermore, bio-augmentation (the addition of exogenous microorganisms with high specific degradation rates to native microbial populations) has been shown to improve treatment performance. The overall aim of this study was to find a microorganism species that would improve the aerobic treatment of dairy industry wastewater. Two bacteria from the genera Klebsiella and Escherichia were examined as promising degrading bacteria. The Bacteria was a simulated dairy industry effluent. The bioremediation potential of these bacteria was investigated and the results suggest that the isolate EF-1 and EF-2 were most efficient for bioremediation and showed reduction in biochemical oxidation demand (BOD), chemical oxidation demand (COD), total dissolve solid (TDS) and total suspended solid (TSS) by (51.51% and 74.60%) for BOD, (35.90% and 41.41%) for COD, (41.29% and 63.20%) for TDS and (54.46% and 72.78%) for TSS respectively after 12 days. Further, the EF-1 isolate identified as Klebsiella pneumoniae and EF-2 isolate identified as Escherichia fergusonii by using biochemical test. [ABSTRACT FROM AUTHOR]
