| 摘 要： | 从厦门海区潮间带石纯、浒苔、江蓠、海兔、海葵及鲨鱼肠道分离得２８９株共附生微生物，以８种敏感菌为指示菌，从中获得拮抗活性的幼苗２８株，放线菌１７株，真菌８株。拮抗细菌以假单胞菌（３９％）、弧菌（２５％）和芽直菌（１４％）为主，主要为抗革兰氏阳性细菌，抗真菌的菌株比例较低。拮抗放线菌分属于链霉菌和小单孢菌，其抗革兰氏阳性菌、阴性菌和真菌的菌株比例分别为６５％、４７％和２３％。拮抗真菌分青霉属和芽枝霉

| Abstract: | The 289 strains of the symbiotic and epiphyte microorganisms were lsolated from marineorganisms (Ulra, Enteromorpha, Gracilaria, Actinia, Mustelus, and Aplysia)collected from theintertidal zone of Xiamen. Among them, 28 strains of bacteria, 17 strains of actinomycetesand 8 strains of fungi have shown to have antagonistic activity on bacterial or fungal growth.the main antibiotic-producing bacteria belong to Pseudomonas (39% ), Vibro (25%) andBacillus (14%). The number of bacterial strains, that inhibits the growth of G bacteria, isthe largest and the number of bacterial strains that inhibits the growth of fungi,is the least.The antibiotic-producing actinomycetes respectively belong to Streptomyes (88%) and Micromonospora (12%), 65% of strains inhibits the growth of G bacteria,47% for G- bacteriaand 23% for fungi. The antibiotic-producing fungi, belonged to 6 different genera, could only inhibit bacterial growth. |
