摘要
从上海郊区海域采集的海水、海泥样中分离出193株海洋细菌,对其进行抑菌活性菌株的筛选。对分离出的菌株分别利用琼脂块法和管碟法进行初筛和复筛,结果显示有29株海洋细菌具有抑菌活性,占总分离菌株的15%,其中抑菌能力较强的G4抑菌谱较广,同时能抑制革兰氏阳性和阴性指示菌。
193 marine bacteria strains were isolated from seawater and marine sediments collected from different areas of Shanghai suburbs. They were screened for antimicrobial active strains and were measure by methods of agar diffusion and cylinder-plate. The results showed that 29 of them possessed antimierobial activity, account for 15 % of total isolated strains. Among them the stronger strain G4 had broader antimierobial spectrum than the other, it could inhibit Gram positive and negative indicators at the same time.
