Description

一种产(-)-α-红没药醇的重组基因工程菌及其制备方法和 用途
技术领域
本发明属于基因重组发酵技术领域,具体涉及一种产(-)-α-红没药醇的重组基因工程菌及其制备方法和用途。
背景技术
红没药醇是一种有机化合物,分子式为C15H26O,是一种存在天然精油中无毒的倍半萜烯醇;在自然界中以两种结构形式存在:β和α。β-红没药醇是从玉米和棉花中收获的,主要用作调味剂。(-)-α-红没药醇主要存在于春黄菊精油中,含量达17%,其右旋体存在于胶杨精油以及某些苦槛蓝属和鼠尾草属的精油中,具有消炎、灭菌、愈合溃疡、溶解胆石等药效,故在医药行业中的用途较广。
(-)-α-红没药醇能够保护和治愈皮肤,使其免受日常张力的影响,能够加速皮肤的治愈过程,尤其适用于作为敏感皮肤和身体,被广泛应用于个人护肤(皮肤和身体的护理液、须后水和晒后护理产品)的配方中,加上其抗炎、天然、安全特性,使其成为一种用于皮肤护理的常用活性成分。国际上仅个人护理产品上的应用年需求量达到400t以上,逐渐成为个人护肤品原料新宠;此外,(-)-α-红没药醇香气清淡愉快,也是一种稳定性较好的定香剂,在香料香精中的应用也日益受到重视;然而,(-)-α-红没药醇作为次级代谢产物,纯天然从植物提取的量俨然无法满足市场的需求,因其受制于生物生长周期,环境等各种因素,扩大生产规模会导致生态环境的破坏甚至物种灭绝;若采用化学合成方法,α-红没药醇复杂手性化学结构,使得直接化学合成难度高,生物活性低以及纯度低等弊端。因此,利用合成生物学构建工程菌实现以廉价的碳源和培养基生产具有高附加值的(-)-α-红没药醇是一条最具有潜力的途径。
目前文献报道中,利用基因工程菌生产(-)-α-红没药醇,发酵罐取得一定成果,但摇瓶产量并不理想;2016年Gui Hwan Han等人以大肠杆菌为宿主细胞,通过质粒过表达德国洋甘菊来源的(-)-α-红没药醇合成酶MrBBS、大肠杆菌来源的ispA以及外源性MVA途径,从而获得最终产(-)-α-红没药醇基因工程菌,发酵48h后产量仅为0.08g/L;CN110016458A公开了一种利用基因工程菌生产(-)-α-红没药醇的方法,其虽然摇瓶产量达到4.15g/L,但还有进一步提高的空间,使发酵罐放大生产后的产量呈倍数级提高。

以下通过试验例进一步说明本发明的有益效果:
试验例1重组大肠杆菌在合成(-)-α-红没药醇中的应用
1、培养基配制
LB培养基组成:蛋白胨10g/L、酵母粉5g/L、氯化钠10g/L,溶剂为去离子水,pH值自然。LB平板是在LB液体培养基中添加终浓度2g/L琼脂。

(2)(-)-α-红没药醇生产
挑取对比例1构建的大肠杆菌工程菌株DH5α/W3110 pSTV28-2&pTrc99A-1在摇瓶进行发酵实验测试(发酵过程中(-)-α-红没药醇合成代谢过程见图4),具体摇瓶发酵实验步骤如下:
挑取在LB固体培养基划线培养过夜的单菌落接种种子培养基,在30℃、200rpm摇床振荡培养8~10h。将培养好的种子按照8%(v/v)接种到发酵培养基,再添加20%(v/v)正十二烷,在30℃200rpm摇床振荡培养至50h,其中发酵3h后添加10μL 0.25M IPTG母液,发酵结束后发酵液取上清即得到(-)-α-红没药醇。
(3)(-)-α-红没药醇含量的测定:
标样准备:配置9g/L(-)-α-红没药醇标样,分别稀释成浓度为10、30、50、70、90mg/L的标样,1mL过膜待测;
样品准备:取1mL发酵液在转速12000rpm下离心5min,两相分离;分离得到的有机相过膜待测;
GC-MS检测方法:柱温控温程序为50℃保持3min;以20℃/min升温到280℃保持5min;进样口温度为200℃;进样模式分流比为10:1;分流流量为10mL/min;色谱柱为安捷伦HP-5MS UI(30m*250um*0.25um);柱流量为:1mL/min;
检测重组E.coli DH5α/W3110 pSTV28-2&pTrc99A-1发酵获得的发酵液中(-)-α-红没药醇的含量、检测结果以及GC-MS图谱图5。由图5可知,将E.coli DH5α/W3110 pSTV28-2&pTrc99A-1分别接种至以葡萄糖为碳源的发酵培养基中发酵50h,可使E.coli DH5αpSTV28-2&pTrc99A-1发酵液中的(-)-α-红没药醇的产量达到5g/L;而E.coli W3110pSTV28-2&pTrc99A-1产量为3.9g/L。
发酵培养基中分别以甘油或葡萄糖为唯一碳源,考察重组E.coli DH5αpSTV28-2&pTrc99A-1在不同碳源下合成(-)-α-红没药醇的能力。(-)-α-红没药醇在摇瓶培养条件下合成产量如图6所示。当甘油为唯一碳源时,摇瓶发酵50h时,菌株E.coli DH5αpSTV28-2&pTrc99A-1合成(-)-α-红没药醇产量达到2.8g/L,比以葡萄糖为唯一碳源产量低,表明以葡萄糖为唯一碳源更有利于合成(-)-α-红没药醇。
试验例2:不同连接短肽对(-)-α-红没药醇产量的影响
挑取实施例1构建的5株分别表达由不同连接多肽连接的α-红没药醇合成酶MrBBS和法尼基二磷酸合酶ispA融合酶的大肠杆菌工程菌株E.coli DH5αpSTV28-21/22/23/24/25&pTrc99A-1在摇瓶进行发酵实验测试。发酵培养基中以葡萄糖为唯一碳源,按试验例1方法发酵生产。(-)-α-红没药醇在摇瓶培养条件下合成产量如图7所示。当摇瓶发酵50h时,菌株E.coli DH5αpSTV28-24&pTrc99A-1合成(-)-α-红没药醇产量达到6.8g/L,其中pSTV28-24质粒图谱见图3。
从图7发酵结果可见:α-红没药醇合成酶MrBBS和法尼基二磷酸合酶IspA之间的连接短肽对红没药醇产量具有较大的影响。其中SEQ ID NO.10编码的连接短肽(氨基酸序列相应为Gly-Ser-Gly-Gly)对红没药醇产量提升有较大促进作用,原因可能为将MrBBS和IspA通过连接短肽融合表达,使两种酶在空间结构上更加接近,便于法尼基二磷酸合酶ispA催化产物法尼基焦磷酸作为红没药醇合成酶MrBBS底物迅速被MrBBS获取进行反应,从而提高(-)-α-红没药醇的最终产量。
综上,本发明通过将特定的基因如mvaKmm等MVA途径基因重组入大肠杆菌,同时在重组大肠杆菌中将MrBBS基因、ispA基因之间通过短肽编码序列连接,并过表达mvaK2、mvaD、idi等基因,使之在生产过程的摇瓶阶段产量就高达6.8g/L,再经发酵罐放大后的产量相对目前公开报道的产量能突破新高,适宜实际推广应用。
