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.

我们最新报道了“代谢发酵”的独特概念，这是一种通过使用混合培养系统从未灭菌的废弃生物质中生产增值产品的发酵。间发酵有几个优点相比，环一般发酵使用纯培养物：不需要灭菌设施，较低的能源成本，不降解的热不稳定化合物，现场处理的废物生物质等，我们调查了“间发酵”的具体特点，L-乳酸生产从食物垃圾使用某些堆肥作为混合种子。结果表明，影响产率、产率、选择性和光学纯度的因素有温度、中和和通气。在最佳条件下，凝结芽孢杆菌作为后发酵的主要菌种增殖。
