Disclosed is an on-site treatment method of food waste generated from multi-unit dwellings and institutional food service facilities, by transporting wastewater-containing food waste to a separation chamber by use of domestic wastewater or an additional transporter; separating the transported food waste to wastewater and food waste; and treating the separated wastewater in a sewage disposal plant, and the separated food waste using disposal equipment. Such food waste can be treated even using disposal equipment of small capacities, due to separation of wastewater and food waste, compared to disposal equipment of large capacities required for treating wastewater and food waste together. Also, the quality of the separated wastewater is better than the conventional quality of wastewater, and thus loads of the sewage disposal plant can be efficiently decreased.

A novel microorganism capable of producing organic acids,sp. 55E, and a process for producing organic acid through anaerobic and aerobic incubation using the novel microorganism are provided. The method of producing an organic acid using the microorganism involves incubatingsp. 55E with Accession Number KCTC 0769BP in a medium under anaerobic or aerobic conditions and obtaining an organic acid from the medium.sp. 55E produces succinic acid, lactic acid, and formic acid under anaerobic conditions saturated with CO, and succinic acid, lactic acid, acetic acid, and formic acid under aerobic or Nanaerobic conditions.sp. 55E is a facultative anaerobe tolerant of oxygen. Thus, the use ofsp. 55E in producing organic acids can eliminate a problem of process instability, which would occur by the presence of oxygen in a fermentation process of producing organic acids using an obligate anaerobic microorganism.
