| 摘 要： | 为探讨根霉固体发酵生产植酸酶的产酶条件,以MR020为试验菌株,研究了产植酸酶活力较高的固体培养基配方。结果表明:以麸皮为基本培养基,添5%的蛋白胨,0.2%NH4Cl、0.01%FeS04、0.07%MgS04组成的培养基在相同条件下产酶活力较高,该菌种在此培养基上培养4.5d(108hr)时达到产酶高峰。

| Abstract: | using Rhizopus.sp MR_ 020 as the test strain,medium for phytase solid fermentation was studied and optimized. The results showed:the suitable medium for creatininase formation was consisted of wheat bran,5% peptone, 0.2% NH_4Cl, 0.01% FeSO_4、 0.07% MgSO_4 the maximum phytase enzyme activities observed incubation 108 hr. |
