摘要: 通过生物胺菌(BAB)筛选培养基的初筛、高效液相色谱(HPLC)-柱后衍生-荧光检测(FLD)技术的分析以及VITEK 2菌种鉴定系统的使用,对鲅鱼鱼肉中的组胺菌(HFB)进行分离和鉴定。结果表明,分离的13株生物胺菌均为革兰氏阴性菌,其中8株为组胺菌。经鉴定,组胺菌分别为大肠埃希氏杆菌(两株)、荧光假单胞菌、侵肺巴斯德菌、泡囊短波单胞菌、居泉沙雷菌、类鼻疽伯克霍尔德菌、杀鲑气单胞菌,鉴定可信性大于87%。

Abstract: In order to analyze the species of histamine-forming bacteria (HFB) in Spanish mackerel meat and prevent histamine poisoning, the isolation and identification of HFB in Spanish mackerel meat were performed by primary strain screening with biogenic amine-forming bacterium (BAB) isolation agar, high performance liquid chromatography (HPLC) and post-column derivatization with fluorescence detector (FLD) analysis and the use of VITEK 2 strain identification system. The results showed that 13 BAB strains isolated from Spanish mackerel meat were all gram-negative bacteria, including 8 HFB strains, which were identified to be Escherichia coli (2 strains), Pseudomonas fluorescens, Pasteurella pneumotropica, Brevundimonas vesicularis, Serratia fonticola, Burkholderia pseudomallei and Aeromonas salmonicida, with a credibility of more than 87%。
