BIOREMEDIATION OF DAIRY EFFLUENT USING CANDIDA INTERMEDIA MTCC 1744 AND KLUYVEROMYCES MARXIANUS MTCC 3772

Abstract

The food sector is one of the highest consumer of water and also the biggest producer of effluent and sludge per unit production. Today, the annual production of processed milk in India is more than 150 million tons. The water requirement for washing and cleaning purpose is in the range of 0.9 to 2 liters of milk being processed. It has high organic load reflected in effluent levels of Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD5), Oil and Grease, Nitrogen, Phosphorus. Physical treatment processes are employed, but biological treatment is cost effective, safe and it relies on microbes that naturally occur in environment. Two yeast strains Candida intermedia MTCC 1744 & Kluyveromyces marxianus MTCC 3772 were employed for the present study and environmental conditions for maximum bioremediation were optimized. All the procedures were carried out as per standard AOAC (2005) methods.
