Effects of temperature and pH on xylitol recovery from oil palm empty fruit bunch hydrolysate by Candida tropicalis

Oil Palm Empty Fruit Bunch (OPEFB) is composed of pentose that can be used as a raw material for the production of xylitol, a potential application in the food and medical areas. The effects of temperature and pH on xylitol bioconversion by yeast sp. Candida tropicalis were investigated. The optimum...
