where maximum COD reduction was found up to 65–70%. Similar decrease in COD of the dairy wastewater (99.9%) was reported by Cosa and Okoh [68] with the consortium of two marine species belonging to Ocenobacillus and Halobacillus. Chatterjee and Pugaht [67] had also reported 67.1% and 48.3% reduction in COD of diary wastewater with use of two bacterial strains namely Neisseria sp. and Citrobacter sp. Vida et al. [71] had also reported COD reduction by 70.7% and 69.5% by using two bacterial isolates BP3 and BP4. The COD of dairy wastewater is mainly influenced by milk, cream or whey [46]. Among the major industries in India, dairy is one of the industries producing odorous and high COD containing wastewater [47]. Microflora of the effluents from a dairy factory in Tehran (Pegah Dairy Processing Plant) were isolated and studied to check reduction in COD of the effluents by Maghsoodi et al. [48].
