The wastewater generated from food industries like dairy and meat processing industries are rich in organic compounds and nutrients having high concentrations of BOD, COD and suspended solids. However, most of the conventional techniques used for treatment are not so eco-friendly. The eco-friendly approaches mostly employ biological aid but are usually ineffective in treating high organic load under extreme conditions. This study uses alkaline protease isolated from Bacillus pseudofirmus SVB1 to treat effluents from dairy industry and domestic sludge. The results obtained from this study indicate that both crude and partially purified alkaline protease performed significantly well in the treatment of effluents from dairy and domestic sewage. They were also able to effectively lyse both Gram positive and Gram negative bacteria. Both crude and partially purified enzyme procured from SVB1 performed efficiently when compared to the already available commercial enzymes used in this study. The efficiency of the extract reduces the overall cost of treatment, hence can potentially be used for treating effluents, enhancing the economy of the entire process.
