الملخص EN
Xylitol fermentation production from corncob acid hydrolysate has become an attractive and promising process.
However, corncob acid hydrolysate cannot be directly used as fermentation substrate owing to various inhibitors.
In this work, soaking in aqueous ammonia (SAA) pretreatment was employed to reduce the inhibitors in acid hydrolysate.
After detoxification, the corncob acid hydrolysate was fermented by immobilized Candida tropicalis cell to produce xylitol.
Results revealed that SAA pretreatment showed high delignification and efficient removal of acetyl group compounds without effect on cellulose and xylan content.
Acetic acid was completely removed, and the content of phenolic compounds was reduced by 80%.
Furthermore, kinetic behaviors of xylitol production by immobilized C.
tropicalis cell were elucidated from corncob acid hydrolysate detoxified with SAA pretreatment and two-step adsorption method, respectively.
The immobilized C.
tropicalis cell showed higher productivity efficiency using the corncob acid hydrolysate as fermentation substrate after detoxification with SAA pretreatment than by two-step adsorption method in the five successive batch fermentation rounds.
After the fifth round fermentation, about 60 g xylitol/L fermentation substrate was obtained for SAA pretreatment detoxification, while about 30 g xylitol/L fermentation substrate was obtained for two-step adsorption detoxification.
