海洋微生物来源纤溶活性化合物的筛选及其分离

目的 从海洋微生物的次生代谢产物中分离具有纤溶促进作用的化合物.方法 采用选择性培养基从海水样品中分离细菌、真菌和放线菌,利用发色底物法筛选产纤溶活性化合物的菌株和确定菌株发酵培养基,通过HPLC分离活性化合物.结果 从离岸100 m处采集的31个海水样品中获得分离菌株936个,从霉菌FG216的次生代谢产物中,发现了具有纤溶促进作用的活性化合物,采用改良的察氏培养基作为发酵培养基,代谢产物的纤溶促进效果最好,并从FG216的发酵液中分离和精制了活性化合物.结论 从海洋微生物的代谢产物中得到了具有纤溶促进作用的活性化合物.

Screening and isolation of fibrinolytic active compound from marine microorganism

Objective To isolate bioactive compound of enhancing fibrinolysis from secondary metabolites of marine microorganism.Methods The separation of microorganism from seawater samples,screening of producing fibrinolytic compound's strain,selection of the active strain's optimum fermentation medium and refining of active compound were done by the method of selective cultivation,measuring of compound's fibrinolytic activity and semipreparative HPLC,respectively.Results Nine hundred and thirty-six single strains fr...
