Effect of temperature on continuous fermentative lactic acid (LA) production and bacterial community, and development of LA-producing UASB reactor

▸ Continuous lactic acid (LA) production by mixed cultures. ▸ Effect of temperature on LA production and bacterial community. ▸ Significant increase of LA production from 50 °C, over 90% LA conversion efficiency. ▸ Pyrosequencing analysis showed a drastic change of bacterial community. ▸ LA-producing UASBr enhanced the productivity up to 4.8 g LA/L/h.
