The bacterial strain Bacillus subtilis UTM 126 produced antimicrobial activity against pathogenic Vibrio species, including V. alginolyticus, V. parahaemolyticus, and V. harveyi. The probiotic effect of B. subtilis was tested by feeding juvenile shrimp (Litopenaeus vannamei) food supplemented with B. subtilis (10(5 )CFU/g) for 28 days before an immersion challenge with V. harveyi at 10(5 )CFU/mL for 24 h. The treatment with B. subtilis UTM 126 decreased final mortality to 18.25%, compared with 51.75% in the control group. Bacillus subtilis UTM 126 has potential applications for controlling pathogenic V. harveyi in shrimp aquaculture.
枯草芽孢杆菌UTM 126菌株对包括溶藻弧菌、副溶血性弧菌和哈维氏弧菌在内的致病性弧菌具有抗菌活性。通过给幼虾（凡纳滨对虾）投喂添加枯草芽孢杆菌（10⁵ CFU/g）的食物28天，然后用浓度为10⁵ CFU/mL的哈维氏弧菌进行24小时浸浴攻毒，来测试枯草芽孢杆菌的益生菌效果。与对照组51.75%的最终死亡率相比，用枯草芽孢杆菌UTM 126处理后最终死亡率降至18.25%。枯草芽孢杆菌UTM 126在对虾养殖中控制致病性哈维氏弧菌方面具有潜在应用价值。
