Kinetics of Lactic Acid Fermentation on Food Waste by Lactobacillus bulgaricus
Lactic acid (LA) production from food waste (FW) is a novel recycling method for organic solid waste. In this study, 35.12g/L LA produced from non-autoclaved FW by Lactobacillus bulgaricus, with a volumetric productivity of 0.98g/(L•h). The kinetic model of lactic acid formation in the FW fermentation at 45 0C and pH 5.5-6.0 was established. A nonlinear parameter estimation procedure was used to obtain optimal kinetic model parameters.
