摘要
纤维素酶能有效地将纤维素物质水解成单糖进而发酵生产乙醇、氢气以及微生物油脂等,因此纤维素酶日益受到人们的关注。但纤维素酶的大规模工业化应用在很大程度上却受纤维素酶活较低以及成本较高的限制。纤维素酶基因克隆为研究纤维素酶的生物合成和作用机制以及了解纤维素酶遗传特性进而构建高效纤维素分解菌开辟了新的途径。
Cellulase has been paid more and more attention for it could hydrolyze cellulosic materials to monosaceharide effectively, and then ferment to ethanol, H2 and microbial oils, etc.. But the production of cellulase in a large-scale industrial operation is largely restricted by low activity of eellulase and high cost. The cloning of cellulase breaks a new path for studying the biosynthesis and action mechanism of eellulase and understanding the genetic characteristics of cellulase to construct efficient decomposing bacteria for cellulose.
