Screening of antagonistic bacteria against aquatic pathogenic Vibrio and isolation of their antibacterial substances
Abstract
为了探索上清液天然抑菌物质最适宜的发酵条件及其稳定性，采用了平板对峙法，筛选对哈维氏弧菌有显著拮抗效果的拮抗菌，通过不同硫酸铵饱和度盐析出抗菌粗蛋白。结果表明：贝莱斯芽孢杆菌（Bacillus velezensis BS2-7）对水产病原—哈维氏弧菌（V. harveyi GDH11385）拮抗效果最显著；发酵培养基和发酵温度对抑菌活性无显著影响，发酵时长对抑菌活性具有显著影响（P
