【摘要】 从福建厦门海沧、集美及漳州浮宫等地采集到的红树林等海洋潮间带的各种腐木样品中分离得到176株海洋木栖真菌,对其进行抗菌活性检测.其结果表明共有96株海洋木栖真菌对大肠杆菌、枯草杆菌及白色假丝酵母中的一种或多种拮抗指示菌具有抑制作用,占供测菌株总数的54.5%.在这些活性菌株中,红树源菌株拮抗比例为30.2%,非红树源菌株拮抗比例为69.8%.具有抗菌活性的菌株主要分布于15个属中,包括木霉Trichoderma、青霉Penicillium、拟青霉Paecilomyces和一些不产孢的分类群.某些稀有真菌如盘多毛孢Pestalotia、茎点霉Phoma也具有一定的抗菌活性.更多还原

【Abstract】 One hundred and seventy-six strains of marine lignicolous fungi wereisolated from mangrove debris and other submerged wood panels which were collected from the intertidal zone around Xiamen for detection of the antimicobial activity. The results showed that ninety-six strains of the fungihave antagonism against one or more indicators, such as Escherichia coli,Bacillus subtilis and Candida albicans. The ratio of active fungi to thetotal isolates is 54.5%, which consists of 30.2% from mangrove debris and 69.8%from other materials. The active marine lignicolous fungi were identified as 15genera, most of which belong to Trichoderma sp., Penicillium sp. and Paecilomyces sp. and some sporeless class. Some rare fungi such as Pestalotia sp. and Phomopsis sp. also present a certain antimicrobial activity.更多还原
