ABSTRACT
Objective To study bioactive metabolite produced by marine actinomyces M326.Methods Based on the index of antimicrobial activity,the relation between activity of metabolite and conditions of culture in different media and time were researched,and the stability of bioactive metabolite treated with different temperatures and pH were obseved,and the bioactive ingredients were extracted and separated by organic solvent and by macroporous resin.Results The GBP medium made by artificial seawater or distilled water were suitable for production of strong bioactive metabolites.The antimicrobial substances were stable under pH 2~11 and were heat-resistant under strong acidic condition.It could not be extracted by usual organic solvent,but could be absorbed by AB-8 macroporous resin under alkaline situation.Conclusion The metabolites have strong activity against gram-positive bacteria and have different antimicrobial activities against gram-negative bacteria and drug-resistant strains moreover,the polarity of antimicrobial substances is strong.
