Abstract:
Endo 1,4-β-d-xylanases (EC3.2.1.8) are one of the key lignocellulose hydrolyzing enzymes. Xylan, which is present in copious amounts on earth, forms the primary substrate of endo-xylanases, which can unchain the constituent monosaccharides linked via β-1,4-glycosidic bonds from the xylan backbone. Researchers have shown keen interest in the xylanases belonging to glycoside hydrolase families 10 and 11, whereas those placed in other glycoside hydrolase families are yet to be investigated. Various microbes such as bacteria and fungi harbor these enzymes for the metabolism of their lignocellulose fibers. These microbes can be used as miniature biofactories of xylanase enzymes for a plethora of environmentally benign applications in pulp and paper industry, biofuel production, and for improving the quality of food in bread baking and fruit juice industry. This review highlights the potential of microbes in production of xylanase for industrial biotechnology.
摘要:
内切1,4-β-d-木聚糖酶(EC3.2.1.8)是关键的木质纤维素水解酶之一。木聚糖,它在地球上大量存在,形成内切木聚糖酶的主要底物,该酶可以将通过β-1,4糖苷键连接的组成单糖从木聚糖主链上解链。研究人员对属于糖苷水解酶家族10和11的木聚糖酶表现出浓厚的兴趣,而置于其他GH家族中的木聚糖酶尚待研究。各种微生物如细菌和真菌携带这些酶用于其木素纤维素纤维的代谢。这些微生物可用作木聚糖酶的微型生物工厂,用于纸浆和造纸工业中的大量环境友好应用。生物燃料生产和提高面包烘焙和果汁行业的食品质量。这篇综述强调了微生物在工业生物技术木聚糖酶生产中的潜力。本文受版权保护。保留所有权利。
