摘　　要：木聚糖酶作为最大商业酶组之一,已广泛应用于食品以及造纸等领域,近年来在医药、生物能源开发、农副作物利用等方向亦出现新应用。木聚糖酶的多数工业应用环境为长期高温、伴酸性或碱性,同时作为木质纤维素降解为生物质燃料的重要一环。随着“可持续发展”的大力倡导,该酶应用可减少化工原料使用,对环境更为友好,嗜热木聚糖酶获得了广泛关注。阐述了不同来源嗜热木聚糖酶的研究以及新的应用方向和局限。As one of the largest commercial enzymes,xylanase has been widely used in food,papermaking and other fields,and in recent years,new applications have appeared in medicine,bioenergy development,agricultural and sideline crop utilization and other directions.Most of its industrial application environment was long-term high temperature,acidic or alkaline,and as an important part of lignocellulose's degradation into biomass fuel,with the sustainable development advocacy,thermophilic xylanase has gained widespread attention.The research of thermophilic xylanase from different sources,as well as new application directions and limitations was briefly described.
