摘　　要：蛭弧菌具有裂解病原菌的功效,可以用作生物净化因子。本实验从海洋环境中分离到1株蛭弧菌(BDK-1)。利用蛭弧菌BDK-1进行消除鸡蛋表面的沙门氏菌的人工模拟实验,结果表明,蛭弧菌BDK-1在其浓度为10~6～10^(10)PFU/mL时,可有效消除鸡蛋表面的沙门氏菌,显示了蛭弧菌在食品卫生安全应用方面的潜在价值。Bdellovibrio can eliminate pathogenic bacterium and can be used as biological purification factor.In the investigation,one strain of Bdellovibrio（BDK-1 ）was isolated from sea mud obtained from ocean circulation.In the simulation decontamination test of Salmonella, BDK- 1 could decontaminate Salmonella effectively when the population of BDK-1 was 10^6- 10^10 PFU/mL, which indicated the good potential value of using Bdellovibrios for biological control or decontamination of pathogens in food safety area.
