The invention discloses gene recombined candida utilis capable of decomposing hemicellulose and applications of the gene recombined candida utilis. The gene recombined candida utilis can stably express xylanase coming from trichoderma reesei and Arabinfuranosidease. With the gene recombined yeast, an integrated biotechnology capable of degrading hemicellulose for co-producing xylooligosaccharide, arabinose and newtol is established. According to the process, 20g/l bagasse hemicellulose is taken as a substrate, after culture for 156h, xylose produced in the middle process is consumed up by the yeast, the yield of xylooligosaccharide is 20%, at the time, the highest yields of newtol and arabinose, namely, 3.5% and 2.7% are achieved, and the hydrolysis rate of hemicellulose is 40.4%. The integrated biotechnology belongs to a co-production technology which is environmentally friendly, convenient and rapid, and effective.
