Description

产T-杜松醇的重组酿酒酵母及其应用
技术领域
本发明属于代谢工程和生物工程领域,具体涉及产T-杜松醇的重组酿酒酵母及其应用。
背景技术
T-杜松醇,分子式C15H26O,分子量222.37,一种三环倍半萜,是一种重要的生物活性物质,天然存在于许多药用植物中。T-杜松醇作为一种重要的植物活性成分,广泛应用于医药和农业等领域,具有多种功能特性。T-杜松醇对金黄色葡萄球菌具有杀菌作用,已成为治疗伤口致病菌的广泛接受的药物。T-杜松醇具有平滑肌松弛作用,可用于治疗腹泻和帮助缓解胃痉挛。研究表明,T-杜松醇具有抗克氏锥虫活性,对哺乳动物细胞无细胞毒性,可作为查加斯病的候选新药。同时,T-杜松醇对多种癌细胞显示出细胞毒性活性,如人肝癌、结肠癌、肺癌和口腔癌细胞,T-杜松醇还表现出对革兰氏阳性菌的抗菌活性、抗真菌活性和抗霉菌活性。此外,T-杜松醇具有抗分枝杆菌活性,对哺乳动物细胞无毒性,因此可以用作抗结核的潜在药物。另外,富含T-杜松醇的精油对农业害虫棉叶虫具有很好杀灭效果,可以用作杀幼虫剂。
目前,T-杜松醇主要是通过传统的植物提取方法获得,然而,这种生产方式周期长且占用大量耕地,不合适用来大规模生产T-杜松醇。
微生物细胞因其生长周期短、操作简便、环境友好、大规模发酵可控等优势而被广泛研究用以替代传统的植物提取法。通过微生物来生产T-杜松醇具有重要的意义。

优选的,所述的重组质粒中有1个或2个3-羟基-3-甲基戊二酰辅酶还原酶基因,3-羟基-3-甲基戊二酰辅酶为独立表达或两个融合表达。融合表达两个3-羟基-3-甲基戊二酰辅酶还原酶基因,可显著提高T-杜松醇产量。
本发明还提供了所述的重组酿酒酵母菌株在生产T-杜松醇中的应用。
