Food waste composed of 30-60% starch, 10-40% lipids and 5-10% proteins(w/w). The increase of food waste is one of the big problem which caused world economic loss and environmental damage. In this study, for the purpose of decomposing food waste, the strain was screened from Korean traditional Nuruk and food waste. Twenty three strains were isolated from 74 isolates of Nuruk, and eleventh strains were isolated from food waste. Among them, 8 kinds of strains which have salt resistance and heat

Six species of mixed strains were inoculated into food waste, and the result after 24 hours decomposition, the reduction of food waste was 52.7% on as biomass basis.
