中文摘要:木聚糖是植物半纤维素的主要成分,是一种复杂的多聚五碳糖。木聚糖酶(xylanase,EC 3.2.1.8)以内切方式作用于木聚糖主链,产生不同链长的寡糖及少量的木糖,是木聚糖降解酶系中最关键的酶。微生物木聚糖酶在食品、饲料等行业均有广泛的应用前景,而其产生的关键是适合的诱导底物及培养条件。不同微生物来源的木聚糖酶特性不同,因而在各领域具有不同的应用特点。本文综述了木聚糖的结构,微生物木聚糖酶的产生、特性及其应用。

Abstract:Xylan is the major constituent of hemicellulose. Due to the structural heterogeneity of the xylans, xylan-degrading enzyme systems include several hydrolytic enzymes. Xylanase(EC 3.2.1.8, 1,4-β-D-xylanase)can hydrolyze β-1,4-glycosidic linkages of the xylan backbone to produce short chain xylooligosacchrides of various lengths. Hence, endo-β-xylanase is the crucial enzyme component of microbial xylanolytic enzyme systems. A large number of bacteria and fungi are known to produce xylanases. Xylanases from microorganisms have attracted a great deal of attention in recent years because of their biotechnological potential application in various industrial processes such as food and feed industries. An important factor for efficient xylanase production is the choice of an appropriate inducing substrate, as well as optimization of the medium composition. Properties of xylanases are different due to various microorganisms. The highlights complex xylan structure, microbial xylanolytic enzymes including their production, properties and their application in industries was reviewed.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
