Over-expression of Xylose isomerase/Xylulokinase and Construction of O2-tolerant hydrogenase in Klebsiella oxytoca HP1

在石化燃料枯竭和全球气候变暖的双重危机下，氢气作为一种可再生、零排放和高热值的清洁能源载体而备受关注。关于氢能的研究主要围绕氢的制取和氢的利用两个方面展开。在众多制氢方式中，生物制氢因其生产成本低、原料来源丰富和环境污染小，从而成为制氢研究的热点。在氢的利用中，燃料电池技术一直以来都是研究的重点。氢酶是一种含金属的氧化还原酶，其广泛存在于微生物中，能够可逆地催化H+的还原和H2的氧化(2H++2e-↔H2)。无论是在氢的制取还是氢的利用中，氢酶都是氢能技术的核心之一。 KlesiellaoxytocaHP1具有高效产氢的特性，且生长迅速，可用于大规模发酵产氢。纤维素是世界上最丰富...Facing energy crisis and global warming, the clean energy carrier H2 has been a hot spot with characters of renewability, zero-emission and high energy yield. Research on hydrogen energy mainly focuses on hydrogen production and hydrogen application. Among all hydrogen production modes, biohydrogen production has become a promising method because of its low cost, abundant source of raw materials a...学位：理学硕士院系专业：生命科学学院_生物化学与分子生物学学号：2162012115231
