摘　　要：从海湾扇贝附着基上分离出 61株异养细菌 ,对其进行 80项生理生化特征测定 ,以数值分类法进行分析。鉴定结果表明 ,海湾扇贝附着基上异养菌属于假单胞菌 ( Pseudomonas)、气单胞菌 ( Aeromonas)、弧菌 ( Vibrio)、芽孢杆菌 ( Bacillus)和产碱杆菌 ( Alcaligenes)。扇贝幼虫附着前附着的细菌主要为芽孢杆菌与假单胞菌 ,扇贝幼虫附着后气单胞菌成为优势 ,弧菌数量明显增加 。The heterotrophic bacteria flora on the adhesive substrate of Argopecten irradians was studied. Sixty one strains of heterotrophic bacteria were isolated from Argopecten irradians attaching substrate. They were identified by 80 characteristics and clustered by numerical taxonomy. The isolates were clustered to Pseudomonas, Aeromonas, Vibrio, Bacillus and Alcaligenes. The dominant taxa on the Argopecten irradians attaching substrate were Bacillus and Pseudomonas before larvae adhesion and then were Aeromonas after adhesion instead. Aeromonas and Vibrio became the second dominant.
