This study was conducted to evaluate possibility for composting by microorganisms in food waste itself. In the result of counting of microorgansm in food waste, the number of bacteria growing at $30^{\circ}C$ and $50^{\circ}C$ were counted $10^5-10^7CFU/g$ and $10^5-10^6\;CFU/g$ in the almost food waste, respectively. Amylase and protease producing microorgansim were counted $10^3-10^7\;CFU/g$ at $30^{\circ}C$ and $50^{\circ}C$. In the result of composting for 30 days, FW1 was reveal that $CO_2$gas production rate and degradation of organic matter were similar to FW2 but higher than that of FW3, FM1 and FM2. Also, In the cases of change of enzyme producing microorgansim during the composting, FW1 were counted $10^5-10^9\;CFU/g$ at $30^{\circ}C$, $50^{\circ}C$ and $60^{\circ}C$ of incubation temperature, while FM1, added to commercial microbial inoculator, were less than that of FM1. Consequently, It was suggested that FW1 was most suitable condition for composting by microorganisms in food waste and there was no need to use microbial inoculator for composting.
