Abstract

本发明是一种生化药品的生产方法,特别涉及 1,6—二磷酸果糖(又称FDP)的生产方法。本方法 以高活性干酵母作底物,采用适当的酶激活剂和抑制 剂调控酶反应,改变细胞壁透性,使FDP通过细胞 膜进入到溶液中,使FDP不断积累,获得FDP对无 机磷高达90%以上的转化率。解决了国内外目前生 产FDP的方法中酶流失过大、副产品过多、工艺流 程复杂过长、操作繁琐以及转化率过低的缺陷。

Description

本发明是一种生化药品的生产方法,特别涉及1,6-二磷酸果糖的生产方法。
1,6-二磷酸果糖,又称FDP(Fructose-1,6-diphosphate),是一种重要的有机磷药物。目前,国际上普遍采用葡萄糖的磷酸化进行FDP的商业化生产,利用有机溶剂甲苯处理酵母细胞,增强其透性,通过Harden-Young发酵法合成FDP;德国《生物化学》杂志1986年8月期上公开了一种“用戊二醛交联酵母细胞连续化生产FDP”,它是在上述生产方法基础上作了适当改进,利用戊二醛把酶固定在酵母上,以防止酶的渗漏,另外,国际上也有用中空纤维超滤分离可渗透的底物,以利连续化生产FDP。
但是,在用上述这些方法生产FDP的过程中,酶流失过大,副产品也多,且工艺流程复杂、过长,操作繁琐。最致命的是FDP的转化率太低,最高只有55%。
本发明的目的就是采用适当的酶激活剂和抑制剂调控酶反应,提高葡萄糖和无机磷的转化率以及发酵单位,简化工艺流程,稳定质量,提高FDP的转化率并降低工业化生产FDP的成本。
本发明的其它目的和优点将在下面的说明中作进一步的阐述。
本发明的基本原理就是改变细胞壁透性,使FDP通过细胞膜进入到溶液中,选择适当的金属离子和AMP/ATP的比例,提高果糖激酶的活性,使FDP不断积累。
根据这一原理及技术方案,制定出如下的生产方法并得以实现。
实施例1:
在150升敞口式发酵罐或摇瓶里加入100升混合液,该混合液由
0.5M  葡萄糖
0.2M NaH2PO4
0.2M Na2HPO4
4g/l  酵母膏
组成,加热并保温在35°-37℃,此时以高活性干酵母12.5kg作底物加入到该混合液中,开动搅拌机搅拌并保温在36°-38℃;待搅拌均匀后加入1升6%的胞质分离剂甲苯,破坏细胞壁,使FDP从细胞内流到溶液中,溶液成细胞悬浮液,再加入8g/l氯化镁,继续搅拌,激活酶的活性,使FDP累积速度加快,3小时30分钟后停止反应,加热至80℃,灭酶;然后将反应液倒入离心机内离心后,得到FDP清液87升,其中含208mMFDP和36mM无机磷,FDP对无机磷的得率为90.5%,大大高于其他方法。
实施例2:
在150升反应罐中加入100升混合液,由
0.40M  葡萄糖
0.15M  磷酸氢二钠
0.25M  磷二氢钠
4g/l  酵母膏
组成,加热并保温在35°-37℃,加入高活性干酵母13Kg作底物,搅拌均匀后再加入6-10g/l氯化镁,搅拌均匀后加入4.5%的Triton  X-300,在36°-38℃温度下搅拌,3小时后中止反应,再加温至80℃灭酶,离心后得86升FDP清液,每升含有214.5mMFDP和30mM无机磷,FDP对无机磷的转化率为92%。
