Optically Pure

ABSTRACT Optically pure d-lactic acid fermentation from arabinose was achieved by using the Lactobacillus plantarum NCIMB 8826 strain whose l-lactate dehydrogenase gene was deficient and whose phosphoketolase gene was substituted with a heterologous transketolase gene. After 27 h of fermentation, 38.6 g/liter of d-lactic acid was produced from 50 g/liter of arabinose.

We report an effective cell recycling continuous fermentation of xylose to l-lactic acid with high concentration, productivity, and yield using strain QU 25. pH was found to affect the yield and corn steep liquor as feeding medium enhanced the yield.
