Abstract：
Hemicellulases are enzymes that hydrolyze hemicelluloses, common polysaccharides in nature. Thermophilic hemicellulases, derived from microbial strains, are extensively studied as natural biofuel sources due to the complex structure of hemicelluloses. Recent research aims to elucidate the catalytic principles, mechanisms and specificity of hemicellulases through investigations into their high-temperature stability and structural features, which have applications in biotechnology and industry. This review article targets to serve as a comprehensive resource, highlighting the significant progress in the field and emphasizing the vital role of thermophilic hemicellulases in eco-friendly catalysis. The primary goal is to improve the reliability of hemicellulase enzymes obtained from thermophilic bacterial strains. Additionally, with their ability to break down lignocellulosic materials, hemicellulases hold immense potential for biofuel production. Despite their potential, the commercial viability is hindered by their high enzyme costs, necessitating the development of efficient bioprocesses involving waste pretreatment with microbial consortia to overcome this challenge.
摘要：
半纤维素酶是水解半纤维素的酶，自然界中常见的多糖。嗜热半纤维素酶，来自微生物菌株，由于半纤维素的复杂结构，被广泛研究为天然生物燃料来源。最近的研究旨在阐明催化原理，通过研究半纤维素酶的高温稳定性和结构特征，在生物技术和工业中都有应用。这篇综述文章的目标是作为一个全面的资源，强调了该领域的重大进展，并强调了嗜热半纤维素酶在生态友好型催化中的重要作用。主要目标是提高从嗜热细菌菌株获得的半纤维素酶的可靠性。此外,具有分解木质纤维素材料的能力，半纤维素酶具有巨大的生物燃料生产潜力。尽管有潜力,它们的高酶成本阻碍了商业生存能力，需要开发有效的生物过程，包括用微生物联合体进行废物预处理，以克服这一挑战。
