title: Lactic acid production from sugar-cane juice by a newly isolated Lactobacillus sp.
abstract: A newly isolated sucrose-tolerant, lactic acid bacterium, Lactobacillus sp. strain FCP2, was grown on sugar-cane juice (125 g sucrose l(-1), 8 g glucose l(-1) and 6 g fructose l(-1)) for 5 days and produced 104 g lactic acid l(-1) with 90% yield. A higher yield (96%) and productivity (2.8 g l(-1 )h(-1)) were obtained when strain FCP2 was cultured on 3% w/v (25 g sucrose l(-1), 2 g glucose l(-1) and 1 g fructose l(-1)) sugar-cane juice for 10 h. Various cheap nitrogen sources such as silk worm larvae, beer yeast autolysate and shrimp wastes were also used as a substitute to yeast extract.
