摘要: 以提高海洋微生物腐皮镰刀菌FG319产出HMG-CoA还原酶抑制剂MFS(Metabolite of Fusarium solani FG319)的数量为目标,优化摇瓶发酵培养基和培养条件,基于摇瓶条件设置发酵罐发酵参数获得MFS。使用GSB培养基、CYM培养基、ATCC培养基、BPY培养基、TYG培养基、OA培养基、CD培养基、PDB培养基,基于摇瓶发酵条件优化发酵罐发酵参数,用HPLC检测MFS的产出量,通过发色底物法评价MFS的HMG-CoA还原酶抑制活性。海洋微生物腐皮镰刀菌FG319的最佳培养基为CD培养基,发酵第7 d HMG-CoA还原酶抑制剂MFS的产量达到最大,诱导物L鸟氨酸盐酸盐提高了4.07倍MFS的产出量,全糖型、pH=6.9、不添加NaCl时海洋微生物腐皮镰刀菌FG319发酵罐发酵产出MFS的数量达到23.47 mg/L,体外评价体系显示MFS抑制HMG-CoA还原酶的活性约是洛伐他汀活性的1.38倍、是普伐他汀活性的1.74倍。通过培养基选择和发酵条件优化,显著提高了海洋微生物腐皮镰刀菌FG319发酵罐发酵产出HMG-CoA还原酶抑制剂的数量。

Abstract: The goal of the present study was to improve the production of HMG-CoA reductase inhibitors MFS (Metabolite of Fusarium solani FG319),through optimizing the fermentation mediums and conditions of marine microorganism Fusarium solani FG319.GSB medium,CYM medium,ATCC medium,BPY medium,TYG medium,Oatmeal medium,Czapek-Dox (CD) medium and potato dextrose broth culture medium were used to optimize the fermentation conditions by shake flask fermentation and fermenter.The production of MFS was analyzed using a HPLC by chromogenic substrate.In addition,an inhibitory effect of MFS on HMG-CoA reductase was determined in vitro. The results showed that CD medium was the best medium for marine microorganism Fusarium solani FG319;maximum production of HMG-CoA reductase inhibitor MFS was achieved on 7th day;inducer L-ornithine hydrochloride had increased the production of MFS (4.07 times);in all sugar type,the marine microorganism Fusarium solani FG319 metabolic MFS quantity was up to 23.47 mg/L without NaCl (pH = 6.9); in vitro evaluation system showed inhibition activity of MFS on HMG-CoA reductase was higher than the activity of lovastatin (1.38 times) and pravastatin (1.74 times).The medium selection and optimization of fermentation conditions significantly improved the production of HMG-CoA reductase inhibitor from marine microorganism Fusarium solani FG319.
