摘　　要：纤维素是地球上含量丰富的可再生资源,对其进行充分利用可有效缓解日益严峻的能源和环境问题。纤维素酶是纤维素生物转化的关键,其催化效果决定了纤维素能源化利用的商业价值。鉴于常规的中温酶很难适应工业化生产中的极端条件,来源于嗜热微生物的纤维素酶引起了科研人员关注。结合国内外研究现状,综述了嗜热纤维素降解菌的种类、纤维素酶类型以及纤维素降解方式,讨论了嗜热纤维素酶在工业生产中的作用及应用现状。最后提出了嗜热纤维素酶大规模应用的技术瓶颈和今后的研究重点,展望了嗜热纤维素酶的商业化前景。Cellulosic biomass is a geographically abundant renewable resource,showing enormous potential to contribute to alleviate the escalating energy and environmental problems.Cellulase is the key to bioconversion of cellulose,and its catalytic effect determines the commercial potential of using cellulose for bioenergy production.In view of the fact that it is difficult for conventional mesophilic enzymes are to adapt to harsh conditions of industrial processing,cellulase from thermophilic microorganisms has attracted the attention of researchers.In this paper,recent progress in thermophilic cellulolytic microorganisms,cellulase types and cellulose degradation strategies was reviewed.Further,the role and application status of thermophilic cellulase in industrial production were discussed.Finally,the technical bottleneck and research emphases of large-scale application of thermophilic cellulose were presented,and the commercial prospect of thermophilic cellulose was prospected.
