Comparative proteomics of the metabolic pathways involved in l-lactic acid production in Bacillus coagulans BCS13002 using different carbon sources

l-lactic acid is an important material widely used in the food industry. Bacillus coagulans BCS13002 was used to produce l-lactic acid through simultaneous saccharification and fermentation (SSF) using two types of carbon source, including corn starch and gelatinized corn starch. The levels of l-lactic acid in B. coagulans BCS13002 culture were 11.75 ± 0.20 and 0.26 ± 0.02 g/L when gelatinized corn starch and corn starch were used as carbon...
