|abstract=Simultaneous liquefaction, saccharification, and fermentation (SLSF) has attracted much attention for the production of bio-based chemicals, including L-lactic acid, due to its high efficiency and low cost. In this study, a lactic acid-producing bacterium with high tolerance of temperature up to 55 °C was isolated and characterized as Enterococcus faecalis [[DUT]]1805. Various strategies of stepwise controlled temperature were proposed and investigated for glucose utilization. The results indicated that E. faecalis [[DUT]] 1805 exhibited an optimal temperature at 50 °C, which could achieve temperature compatibility of enzyme, saccharification, and fermentation, and decrease the possibility of contamination by the other microorganisms during the large-scale fermentation. To reduce the cost of raw material and operation for lactic acid production, aging paddy rice with hull (APRH) was used in L-lactic acid production by simultaneous liquefaction, saccharification, and fermentation (SLSF). An open SLSF operation at 50 °C and pH 6.5, and 17% (w/v) solid loading in 5 L bioreactors was demonstrated with the lactic acid titer, yield, and productivity of 73.75 g/L, 87% to initial starch, and 2.17 g/(L h), respectively.
