植物基因工程改善生物质能利用的研究进展

利用植物木质纤维资源发酵生产乙醇越来越受到人们的重视,但是要实现工业化生产仍然存在很多难题。最近,利用植物基因工程技术,改善植物自身性状,包括减少植物自身细胞壁中木质素含量、细胞中积累表达纤维素酶和木聚糖酶等方法,使自生产生的生物质更利于降解利用。目前,对这种新的能源转基因植物的研究取得了一定进展。

Progress on Plant Genetic Engineering for Bio-fuel Plant

Production of the cellulosic ethanol is the researching focus notwithstanding facing many challenges.Plant biomass is converted to fermentable sugars for the production of ethanol using pretreatment processes that disrupt the lignocellulose and remove the lignin,thus allowing the access of microbial enzymes for cellulose deconstruction.Recent advances in plant genetic engineering could reduce biomass conversion costs by developing plant with less lignin,plant that self-produce cellulase and xylase for cellulose degradation.
