Description
技术领域
本发明涉及微生物及生物化工领域,特别涉及一株能够在非水相体系中催化豆腐果苷生成酯衍生物的酵母属菌种及其筛选方法和应用。
背景技术
豆腐果苷作为山龙眼果实中的主要活性成分,目前已在临床上用于治疗各种疾病,如神经衰弱综合症、三叉神经痛和血管性头痛等。最近的一些研究发现,豆腐果苷还具有治疗抑郁症和与黑色素沉着相关的皮肤病的潜力。然而,豆腐果苷是一种多羟基化合物,脂溶性差,生物利用度较低。研究证明,豆腐果苷酯类衍生物具有比亲代化合物更好的生物活性和生物利用度。肉桂酸属于酚酸类化合物,广泛存在于自然界中,具有抗氧化、抑制酪氨酸酶活性、抗肿瘤、增强免疫等多种生物活性。因此,在保持豆腐果苷原有基本骨架结构基础上对其进行肉桂酸酰化修饰改造,可以获得生物活性提高且具有良好生物利用度的豆腐果苷酯衍生物。和纯酶催化剂相比,使用微生物全细胞催化剂,避免了纯酶制剂繁琐的制备过程,极大地降低了生物催化的成本,而且全细胞具有完整的细胞结构,给酶提供了一个天然保护屏障,可以最大程度地保持酶在有机溶剂中的构象和催化活性。因此筛选一种用于豆腐果苷化合物结构修饰的全细胞催化剂具有极高利用前景,其中来源于假丝酵母属的微生物已经在生物催化中得到了较多利用,而通过进一步定向选育的方法获得用于豆腐果苷结构修饰的酵母属菌种具有较高利用价值。

本发明还提供了一种所述的酵母属菌种在非水相条件下作为全细胞催化剂在豆腐果苷酰化反应中的应用。
有益效果:豆腐果苷是中药材山龙眼的主要功能成分,但其脂溶性较差、生物利用度低,需要对其进一步结构修饰才能提高其应用效果。本发明是专门针对豆腐果苷酰化反应开发的微生物全细胞催化剂,通过微生物菌种筛选程序,获得了一株酵母属菌种(Limtongozyma cylindracea)SA-X,该菌种的全细胞催化剂可以在非水相条件下保持活力,并能高效地催化豆腐果苷生成酯衍生物,大大提高了豆腐果苷的药用价值。全细胞催化是指利用完整的生物有机体(即全细胞、组织甚至个体)作为催化剂进行转化,其本质是利用细胞内的酶进行催化;由于是全细胞催化剂,与现有技术中的酶催化相比,全细胞催化具有以下更多的优点:
(1)全细胞催化剂的制备简单易得,可以省略繁琐的酶分离纯化和固定化工艺,降低生产成本;
(2)全细胞具有完整的细胞结构和细胞膜,酶以天然固定化的方式被保护于细胞中,有利于在有机溶剂、极端pH、高温等反应环境中最大程度地保持酶的构象和催化活性;
(3)全细胞可以给多步生物转化反应提供不同的酶系和辅助因子,而且可以有效地实现辅酶再生;
(4)全细胞催化剂不仅可以催化自身的底物及其类似物,也可催化外源添加的天然底物类似物。
实验表明:该酵母属菌种SA-X(CGMCC No.20048)在非水相条件下作为全细胞催化剂,能够显著提高豆腐果苷酰化反应的催化活性,豆腐果苷肉桂酸酰化反应中,以脱水有机溶剂为反应体系,豆腐果苷20mM,肉桂酸乙烯酯100-400mM,酵母属菌种菌种SA-X全细胞40-80mg/mL,40-50℃,200r/min反应12h取样经高效液相检测出峰时间13.67min的产物峰面积比达99%。
该菌株经种子液培养基摇瓶培养24h后,以2%的接种量于发酵液培养基摇瓶培养48h,离心弃去上清液得到湿菌体,用去离子水洗涤两次离心,真空冷冻干燥,获得的冻干菌体即为酵母属菌种SA-X全细胞催化剂,生物量可达1.9g/L。
