摘　　要：本研究从海参、海胆、海葵、海兔、石莼、羊栖菜、裙带菜分离得到125种共附生海洋微生物,以6种敏感菌为指示菌,从中筛选出具有抑菌活性的细菌21株,放线菌8株,真菌2株。21株抑菌海洋细菌中芽孢杆菌属为7株,占33.3%;弧菌属为11种,占52.2%;其余3株为假单孢杆菌属,占14.5%。8株抑菌海洋放线菌中链霉菌属为5株,占62.5%;小单孢菌属为3株,占36.5%。2株抑菌海洋真菌均为青霉属。125 strains of the symbiotic and epiphyte microorganisms were isolated from marine organisms (sea cucumber, sea urchin,anemone, sea actinia, Ulra, Sargassum, Undaria). Among them,21 strains of bacteria,8 strains of actinomycetes and 2 strains of fungi showed antagonistic activity on bacterial or fungal growth. In the 21 strains of bacteria, 7 strains belong to Bacillus sp., 11 strains Vibrio sp., and 3 strains Pseudomonas sp.. In the 8 strains of actinomycetes, 5 strains belong to Streptomyces sp., 3 strains Micromonospora sp., 2 strains fungi Penicillum sp..
