Microbial mannanases have become biotechnologically important since they target the hydrolysis of complex polysaccharides of plant tissues into simple molecules like manno-oligosaccharides and mannoses. The role of mannanases in the paper and pulp industry is well established and recently they have found application in the food and feed technology, coffee extraction, oil drilling and detergent industry. Mannanses are enzymes produced mainly from microorganisms but mannanases produced from plants and animals have also been reported. Bacterial mannanases are mostly extracellular and can act in a wide range of pH and temperature, though acidic and neutral mannanases are more common. This review will focus on complex mannan structure and the microbial enzyme complex involved in its complete breakdown, mannanase sources, production conditions and their applications in the commercial sector. The reference to plant and animal mannanases has been made to complete the overview. However, the major emphasis of the review is on the microbial mannanases.

微生物甘露聚糖酶：生产和应用概述。

微生物甘露聚糖酶已成为生物技术上重要的技术，因为它们将植物组织中的复杂多糖水解为甘露寡糖和甘露糖等简单分子。甘露聚糖酶在造纸和纸浆工业中的作用是众所周知的，最近它们已在食品和饲料技术，咖啡提取，石油钻探和洗涤剂工业中得到应用。甘露聚糖酶是主要从微生物产生的酶，但是也已经报道了从动植物产生的甘露聚糖酶。细菌甘露聚糖酶大多在细胞外，可在很宽的pH和温度范围内起作用，尽管酸性和中性甘露聚糖酶更为常见。这篇评论将重点讨论复杂的甘露聚糖结构和涉及其完全分解的微生物酶复合物，甘露聚糖酶来源，生产条件及其在商业领域的应用。参考了植物和动物甘露聚糖酶以完成概述。但是，该综述的主要重点是微生物甘露聚糖酶。
