摘要:
红曲色素(Monascus  pigments, MPs)和洛伐他汀(Lovastatin)是两种具有极高营养、保健和药用价值的红曲菌代谢产物,寻找挖掘高产MPs和洛伐他汀的红曲菌,具有重要实践意义。从土样中分离得到红曲菌A1和A2,在对其进行分类鉴定的基础上,采用分光光度法对MPs的色价和洛伐他汀含量进行测定,并通过单因素和正交试验对发酵培养基进行了优化。结果表明:菌株A1和A2隶属于紫色红曲菌(Monascus purpureus)。在基础培养基中,菌株A1和A2的MPs色价分别为3287.11、2561.30 U/g,洛伐他汀含量为31.35、33.74 μg/mL。通过 L16 (45)正交试验优化培养基,获得产MPs最优配方为乳糖20 g/L、KNO 3 5 g/L、KH 2PO 4 4 g/L、KCl 2 g/L、Na 3C 6H 5O 7 2 g/L,产洛伐他汀最优配方为乳糖20 g/L、KNO 3 15 g/L、KH 2PO 4 2 g/L、KCl 6 g/L、Na 3C 6H 5O 7 .4 g/L。在最优培养基中A1菌株总色价可达15851.98 U/g,提高了3.82倍,洛伐他汀含量为122.96 μg/mL,提高了2.92倍;A2菌株总色价为8933.58 U/g,提高了2.49倍,洛伐他汀含量达198.26 μg/mL,提高了4.88倍。该文为红曲菌资源库提供了优秀潜力菌株,为工业上大规模生产MPs和洛伐他汀奠定了理论基础并提供了实际方案。
