  • 方法二:L-苯丙氨酸的制备方法很多, 有蛋白质水解提取法, 直接发酵法, 化学合成等。 化学合成法有苯甲醛法和苯乙醛法。 苯甲醛法 以苯甲醛和乙酰甘氨酸作用生成乙酰氨基桂皮酸, 然后催化加氢还原, 得乙酰-DL-苯丙氨酸(Ac-DL-phe), 最后经氨基酰化酶水解, 可拆分生成L-苯丙氨酸。 利用氨基酰化酶的专一性, 只水解Ac-L-phe的酰氨键, 生成L-phe, 而不能水解Ac-D-phe的酰胺。 然后根据L-phe和Ac-D-phe在水中的溶解度不同进行分离。而分离出的Ac-D-phe又可经消旋化生成Ac-DL-phe。 再一次重复水解、分离。 依次类推, 可将Ac-DL-phe全部转化为L-phe。 固定化氨基酰化酶的制备 将DEAE-sephadexa-50放入去离子水中充分浸泡后, 再依次用10倍量的0.5mol/L HCl和0.5mol/L NaOH溶液充分搅拌处理30min。 然后用去离子水洗至中性, 最后分别用0.1mol/L及0.01mol/L的pH=7.0的磷酸缓冲液处理1-2h, 滤干, 备用。 取经培养40-50h 的米麯扩大麯, 用其6倍量的支离子水分2次提取, 提取液用2mol/L的NaOH溶液调pH至6.7-7.0。 然后按100L酶液和1kg湿DEAE-sephadex A-50的比例混合, 于0-4℃搅拌吸附4-5h后, 过滤取DEAE-sephadexA-50, 并分别用去离子水0.1mol/L NaAc溶液、0.01mol/L 的pH=7.0的磷酸缓冲液洗涤3-4次。 过滤得固定化氨基酰化酶, 加1%甲苯放入冷库中贮存备用。 酶水解 在1000L水解罐中, 加入700L 0.1mol/L Ac-DL-phe钠盐溶液, 再逐步加入6mol/L的HCl调溶液pH至6.7-7.0, 再加入15-20kg固定化氨基酰化酶, 维持50℃约4h进行酶选择性水解反应后, 过滤取滤液, 得酶水解液(含L-phe和Ac-D-phe混合液)。 分离 将酶水解液用6mol/L的HCl调pH至4.8-5.1, 减压浓缩至35L左右, 并将其放置于0℃结晶过夜, 过滤取结晶, 用10L冷乙醇洗涤, 于80℃烘干3-
