Directed Evolution and Simultaneous Release Reasearch of Recombinant Cellulases

Abstract

能源短缺和环境污染是我国乃至全球可持续发展面临的两大挑战。随着人口的增加和现代化工业进程的持续发展,有限的不可再生的煤炭等化石能源已无力支撑世界对于能源的巨大需求。开发新的、清洁环保的、可持续的替代能源,成为解决这两大挑战的主要方案。利用大自然中广泛的生物质为前体,经过一定的转化和利用,将储存在其中的太阳能变成燃料等可以直接利用的能源,同时在此过程中可以得到一定的化学品,这种生物炼制的理念被科学界广泛接纳并加以实践。木质纤维素作为地球上蕴藏最丰富的生物质资源,一直是生物质能研究的重点,通过纤维素酶,将木质纤维素降解成糖,然后经过发酵等生物转化生成最终的生物质燃料是一条行之有效的利用途径。 纤...Energy shortage and environmental pollution are two of main challenges to human being in sustainable development in China and the whole world.
