基因工程改善植物生物质能利用的研究进展

利用植物木质纤维资源发酵产乙醇越来越受到人们的重视，但是要达到工业生产仍然存在很多难题。最近在利用植物基因工程技术改善植物自身性状，以利于能源植物的研究方面取得了一定的进展，这些研究包括减少植物自身细胞壁中的木质素含量、细胞中积累表达纤维素酶和木聚耱酶等的方法，使产生的生物质更利于降解利用。

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.
