| Research Abstract |
We newly reported unique concept of "meta-fermentation", a fermentation that enables production of value-added products from non-sterilized waste biomass by using a mixed culture system. The meta-fermentation has several merits compare ring to the general fermentation using a pure culture: no need of sterilization facility, lower energy cost, no degradation of heat labile compounds, on-site treatment of waste biomass, etc. We investigated specific features of 'meta-fermentation", L-lactic acid production from food waste using certain compost as a mixed seed. It was found that factors affect on yield, productivity, selectivity, and optical purity were temperature, neutralization, and aeration. Under the best condition, Bacillus coagulant proliferate as a major species in the meta-fermentation.
