最近的研究表明，使用益生菌是控制海洋气单胞菌的另一种选择。然而，针对鳗鱼中嗜水气单胞菌感染的益生菌很少。在本研究中，从咸水底泥中分离到一株对鳗鱼致病嗜水气单胞菌有潜在拮抗作用的菌株G1。经API鉴定试剂盒初步鉴定为淀粉液化芽孢杆菌，系统发育分析证实为淀粉液化芽孢杆菌(B.amyloliquefaciens)(GenBank登录号为DQ422953)。此外，它对哺乳动物是安全的，具有广泛的抗A。在体内外均表现出明显的抑制鳗鱼致病嗜水气单胞菌生长的作用。据我们所知，这是首次从微咸水沉积物中分离到一株对鳗鱼致病嗜水气单胞菌有潜在拮抗作用的淀粉解性芽孢杆菌菌株。
Recent studies have revealed that the use of probiotics is an alternative to control marine aeromonas. However, few probiotics are available against Aeromonas hydrophila infections in eels. In the present study, a potential antagonistic strain G1 against the eel-pathogenic A. hydrophila was isolated from sediment underlying brackish water. Its extracellular products with antibacterial activities were shown to be stable under wide range of pH, temperature, and proteinase K. It was initially identified as Bacillus amyloliquefaciens using API identification kits and confirmed to be B. amyloliquefaciens strain (GenBank accession number DQ422953) by phylogenetic analysis. In addition, it was shown to be safe for mammalians, had a wide anti-A. hydrophila spectrum, and exhibited significant effects on inhibiting the growth of the eel-pathogenic A. hydrophila both in vitro and in vivo. To the best of our knowledge, this is the first report on a promising antagonistic Bacillus amyloliquefaciens strain from brackish water sediment against eel-pathogenic A. hydrophila.
