摘要 | 天然产油微生物产生的脂肪酸多以甘油三酯形式贮存在细胞内,需要从细胞内提取,工艺复杂、生产成本高,且严重污染环境。工程大肠杆菌定向调控生产游离脂肪酸已成为近年来的研究热点,是缓解能源危机,提供优质、低成本油脂原料的有效途径。本文从大肠杆菌脂肪酸胞外分泌相关基因(tesA、fadD、fadL)和调控蛋白 (MsbA)两个方面综述脂肪酸胞外分泌调控研究进展,并提出了利用分子生物学和代谢工程手段对大肠杆菌脂肪酸代谢定向调控,生产胞外游离脂肪酸的新的研究方向。 |
其他摘要 | Fatty acids produced by oil-producing microorganisms are stored in cells as the form of triglyceride. The extraction of these fatty acids from the cells is involved in complex processing, high production cost and serious environmental pollution. Targeted regulation for the production of free fatty acids by engineered E. coli strains is becoming one of the hottest topics in current research, which will be an effective strategy for reducing energy crisis and providing high-quality and low-cost raw materials of oil. The research progress of some genes (tesA, fadD and fadL) and regulatory protein (MsbA) related to extracellular secretion of fatty acids in E. coli has been reviewed in this paper. Meanwhile, the target regulation of fatty acid metabolism by using molecular biology and metabolic engineering strategies has been proposed, with the aim of provideing a new direction for producing extracellular fatty acids. |
