摘　　要：木聚糖是植物半纤维素的主要成分,是自然界中仅次于纤维素的可再生资源。木聚糖酶是一类重要的木糖苷键水解酶酶系,可将木聚糖逐次降解为低聚木糖及木糖,在饲料、造纸、食品和生物转化等行业应用广泛。目前利用微生物发酵生产木聚糖酶的研究很多,菌种涉及到细菌、真菌等,其发酵生产木聚糖酶的工艺、产量及特性也各有不同,对此进行了综述,并展望了木聚糖酶发酵生产的研究方向。Xylan is the major component of hemicellulose,which is the second largest recyclable natural resource after cellulose.And xylanase is a very important enzyme system which can break down xylan into xylooligosaccharides and xylose,thus it has a high potential for use in feed,paper making,food industry and biotransformation.There are many researches on microbial express xylanase,that involved bacteria and fungi.The process of ferment,yield and characteristic of xylanases were reviewed.The prospect for development of xylanase production was also discussed here.
