Abstract
The inhibition of lactic acid fermentation by wood hydrolyzate was decreased (approx. 20%) by adaptation of Enterococcus faecalis RKY1 to wood hydrolyzate-based medium whereby lactic acid productivity and cell growth were enhanced by 0.5 g l−1 h−1 and 2.1 g l−1, respectively. When the diluted or concentrated wood hydrolyzate (equivalent to 25–100 g glucose l−1) was supplemented with 15 g yeast extract l−1, 24–93 g lactic acid l−1 was produced at a rate between 1.7 g l−1 h−1 and 3.2 g l−1 h−1.
