肌苷酸二钠盐制备
方法一、肌苷酸脱磷酸法
肌苷酸二钠的制备 棒状杆菌269发酵,发酵液去菌体,吸附,洗脱,浓缩,加乙醇,pH7-7.5条件下结晶可得肌苷酸二钠。
棒状杆菌269[发酵]→发酵液[去菌体,吸附,洗脱,浓缩]→浓缩液[乙醇]→[pH7-7.5]肌苷酸二钠
肌苷粗品的制备 在乙酸缓冲液中,调pH5.4-5.6,加压137-147kPa,脱磷酸5h,可得肌苷粗品。
肌苷酸二钠[乙酸,加压]→肌苷
精制 蒸馏水溶解,pH=6,重结晶,可得精品。
方法二、一步发酵法
菌株选育 变异芽孢杆菌7171-9-1移接到斜面培养基上,30-32℃培养48h。斜面培养基成分为葡萄糖1%,蛋白胨0.4%,酵母浸膏0.7%,牛肉浸膏1.4%,琼脂2%,在pH7、120℃灭菌20min。
变异芽孢杆菌7171-9-1[斜面培养]→[30-32℃, 48h]菌种斜面
种子培养
一级种子:培养基成分为葡萄糖2%,蛋白胨1%,酵母浸膏1%,玉米浆0.5%,尿素0.5%,氯化钠0.25%。灭菌前pH 7,用1L三角瓶装150ml培养基,115℃灭菌15min。每个三角瓶中接入白金耳环菌苔,在往复式摇床上,32℃±1℃培养18h。
二级种子:培养基同一级种子,放大50L发酵罐,定容体积25L,接种量 3%,32℃±1℃培养12-15h,搅拌速度320r/min,通风量1:0.25V/(V·min),生长菌指标 A(650nm)=0.78,pH=6.4-6.6。
菌种斜面[摇床振荡]→[pH7, 32℃±1℃, 18h]一级种子培养液[50L发酵罐]→[pH6.4-6.6, 32℃±1℃, 12-15h]二级种子培养液
发酵 50L不锈钢标准发酵罐,定容体积35L。培养基成分为淀粉水解糖10%,干酵母水解液1.5%,豆饼水解液0.5%,尿素0.4%,硫酸镁0.1%,氯化钾0.2%,磷酸氢二钠0.5%,硫酸铵1.5%,有机硅油0.05%。pH=7,接种量0.9%,32℃±1℃培养93h,搅拌速度320r/min,通风量1:0.5V/(V·min)。500L发酵罐,定容体积350L。培养基成分为淀粉水解糖10%,干酵母水解液1.5%,豆饼水解液0.5%,硫酸铵1.5%,硫酸镁0.1%,氯化钾0.2%,磷酸氢二钠0.5%,碳酸钙1%,有机硅油小于0.3%。pH=7,接种量7%,32℃±1℃培养75h,搅拌速度230r/min,通风量1:0.25V/(V·min)。
20000L 发酵罐,培养基同上,接种量2.5%, 35℃±5℃培养83h。
二级种子培养液[50L发酵罐]→[pH7, 32℃±1℃, 93h]发酵液[500L发酵罐]→[pH7, 32℃±1℃, 75h]发酵液[20000L发酵罐]→[pH7, 35℃±1℃, 83h]发酵液
提取、吸附、洗脱 将发酵液30-40L 调pH=2.5-3,连同菌体通过2个串联的3.5kg 732H树脂柱吸附。用相当于树脂总体积3倍的pH 3水洗1次,把两柱分开,用pH 3水把肌苷洗脱下来,再经769活性炭柱吸附肌苷,先用2-3倍体积的水洗涤,再用70-80℃水洗,70-80℃,1mol/L氢氧化钠溶液浸泡30min,最后用0.01mol/L氢氧化钠溶液洗脱肌苷,收集洗脱液,真空浓缩,pH11或6放置,过滤,得粗品。
发酵液[732树脂柱]→[pH2.5-3]吸附物[水]→[pH2.5-3]洗脱液[769活性炭柱]→吸附物[蒸馏水,氢氧化钠]→[70-80℃][氢氧化钠]→[70-80℃]洗脱液[浓缩结晶]→[pH11或6]肌苷粗品
精制 将粗品配成5%-10%的溶液,加热溶解,抽滤,冷却,过滤,少量水洗,烘干,即得肌苷精制品。
肌苷粗品[蒸馏水]→[重结晶]肌苷成品。
