氨基酸是组成蛋白质的基本单位,是生命机体之营养、生存和成长所必需的重要物质,在生命体内的物质代谢、信息传递方面扮演重要角色。因此,氨基酸广泛应用于医药、食品、农业、畜牧业等领域。
L-丝氨酸虽属于非必需氨基酸,但具有许多重要的生理功能和作用:
(1)合成嘌呤、胸腺嘧啶、胆碱的前体;
(2)L-丝氨酸羟基经磷酸化作用后能衍生出具重要生理功能的磷丝氨酸,是磷脂的主要成分之一;
(3)具有稳定滴眼液pH值的作用,且滴眼后无刺激性;
(4)重要的自然保湿因子(NMF)之一,皮肤角质层保持水分的主要角色,高级化妆品中的关键添加剂。
在世界氨基酸生产行业中,L-丝氨酸是工业化生产难度较大的氨基酸。虽然L-丝氨酸可从蚕丝水解液中提取,但是,其得率低,成本高,利润薄。日本采用前体发酵法生产L-丝氨酸,工业化产酸水平为2%左右。 由于L-丝氨酸生产水平较低,因而成为氨基酸配套生产中的关键品种和高价氨基酸。从目前的发展趋势看,谁能抢先成功地提高这种氨基酸的生产水平,谁就能赢得高额利润。因此,L-丝氨酸是目前世界氨基酸生产行业中的研究热点。 L-丝氨酸的研究和生产在我国尚属空白。
应用范围 :
目前,国内L-缬氨酸主要用于配制复合氨基酸制剂。国外,L-缬氨酸除用于配制复合氨基酸制剂外,还用于高级化妆品等。
市场分析 :
氨基酸是组成蛋白质的基本单位,是一切生命不可缺少、不可替代的一种生存、成长所必需的营养素,因而广泛应用于医药、食品及饲料等行业。随着人民生活水平的提高,无副作用的氨基酸制剂(结晶氨基酸配制的氨基酸输液和氨基酸口服液)将逐年增加。据上海医药工业研究设计院氨基酸中心统计,全国氨基酸制剂年产量平均递增20%以上。世界上除日本生产外都不生产,因此,发酵法生产L异亮氨酸具较有广阔的市场前景。近期,全世界年消耗量达几百吨,远期将上千吨。
性能指标:
实验室摇瓶产酸率达2.0~2.5%; 10吨发酵罐分批发酵产酸率1.5~2.0%; 总提取率45~50%。
生产条件:
必须具备水电汽(双回路供电或停电时可用自备发电),周围环境较好。最好是通风发酵的制药厂或收购一家通风发酵的制药厂,这样不仅可节约投资,而且上马较快。
效益分析:
投资1000~1200万元 年产30吨(其中10吨医药级内销、20吨化妆品级) 年产值2400万元 年利税1100万元
