摘要
能高效代谢木质纤维素水解液中的可发酵糖、同时可耐受/分解发酵抑制剂的菌种,是利用木质纤维素为原料生产燃料乙醇技术的关键。基因组改组技术是近些年发展起来的一项新型育种技术,该技术已运用于食品和医药行业菌种的改良。本文综述了基因组改组技术的原理、方法、特点、及其运用,并对其在木质纤维素水解液乙醇发酵菌种选育方面的应用进行了展望。
Commercial production of bioethanol from lignocellulosic hydrolysates requires efficient fermenting strains. The abilities of the strain to converting all types of sugars in the hydrolysate to ethanol in high yield and to effectively tolerating/metabolizing inhibitors are necessary. Genome shuffling is a novel method for breeding, and it has been applied in pharmaceutical and food industry. This review summarized the technique of genome shuffling including principle, process, applications and its prospect for strains improvement in ethanol production from lignocellulosic hydrolysates.
