Recombinant lactobacillus for fermentation of xylose to lactic acid and lactate
First Claim
1. A homofermentative microorganism Lactobacillus MONT4 containing exogenous genes encoding xylose isomerase and xylukokinase which functions with transaldolase and transketolase enzymes in the pentose phosphate pathway for homofermentating xylose to lactic acid, wherein the microorganism homofermentates xylose to lactic acid in high yields of 94% of maximum yield based upon an amount of consumed sugar and wherein said microorganism without said exogenous genes being incapable of homofermentating said xylose to lactic acid.
