产蜡酯聚球藻PCC7002的构建
SYNECHOCOCCUS SP. PCC 7002 ENGINEERED FOR WAX ESTER PRODUCTION
-
摘要: 蜡酯是由含C16以上偶碳的高级脂肪酸与高级脂肪醇酯化形成的中性酯, 是一种重要的经济油脂, 被广泛应用于纺织、医药、化妆品和食品等行业。液态不饱和蜡酯还能作为航空航天工业、人工心脏、精密仪器仪表和特种机械等高科技领域专用的润滑剂[1,2]。目前使用的蜡酯主要来源于动植物及矿石资源, 来源十分有限, 且提取比较困难; 通过化学方法生产蜡酯则存在条件难以控制和产物分离困难等问题。因而, 蜡酯的价格十分昂贵, 这极大地限制了蜡酯的使用。所以, 开发完全以廉价可再生的原料合成的新型蜡酯来替代传统蜡酯成为了工业生产的必然要求。
