Possibility of L-(+)-lactic acid fermentation using malting, brewing, and oil production by-products.
Waste Management(2018)
摘要
•Brewer’s spent grain hydrolysate was used in L-(+)-lactic acid fermentation.•Addition of by-products extracts on fermentation efficiency was investigated.•L-(+)-LA yield (86%) and productivity (0.95 g/L h−1) in batch fermentation.•L-(+)-LA yield (88%) and productivity (1.19 g/L h−1) in fed-batch fermentation.
