摘要： Provided are a novel Candida tropicalis CJ-FID (KCTC 10457BP) derived from honey and a method for producing xylitol using the same. The method includes culturing the Candida tropicalis CJ-FID itself or an alginate-immobilized Candida tropicalis CJ-FID in a fermentation medium containing high concentration xylose and sucrose to obtain xylitol-containing culture, followed by purification with an activated charcoal column and anion column, to finally obtain a powdery xylitol. Therefore, high purity xylitol can be produced with high yield and productivity.

摘要： The present invention relates to an environmentally friendly, simple and economic process for producing xylose. The process comprises the steps of: a) countercurrently extracting tropical fruit biomass by hydrolysis with sulfuric acid to obtain a high-concentration xylose extract; b) adjusting the extract to a pH of 1.5-2.5 and decolorizing and filtering the pH-adjusted extract; c) desalting the filtrate in an electrodialysis device; and d) recycling a waste sulfuric acid solution recovered from step c), to step a), and concentrating and directly recovering the desalted filtrate to obtain xylose crystals.
