摘要
代谢工程是指通过某些特定生化反应的修饰来定向改善细胞的特性或运用D N A重组技术创造新的化合物。利用生物技术的代谢工程构建发酵型基因工程菌,将可再生生物质资源转化生产燃料酒精,是解决人类能源紧缺、走可持续发展道路的有效途径。利用代谢工程构建可发酵生物质资源,转化生产燃料酒精的基因工程菌有酿酒酵母(Sc.erevisiae)基因工程菌、大肠杆菌(E c.oli)细菌基因工程菌和运动发酵单孢菌(Zym om onas m obilis)基因工程菌。(孙悟)
Metabolism engineering referred to the improvement of cellular properties by special biochemical reactions or the construction of new compounds by DNA recombination techniques. The construction of fermenting gene-engineering bacteria by biotechs that could transfer renewable resources into fuel alcohol was considered as an effective approach for sustainable development to settle the problem of energy scarcity. Such gene-engineering strains include S.cerevisiae gene-engineering strain, E.coli gene-engineering bacteria strains and Zymomonas mobilis gene-engineering strains. （Tran. by YUE Yamz）
