摘    要:粪肠球菌和屎肠球菌是发酵香肠中常检出的2种主要的产酪胺和苯乙胺微生物。将粪肠球菌和屎肠球菌按照不同比例进行混合接种培养,发现在48h连续培养过程中,当粪肠球菌和屎肠球菌以1∶9比例混和接种培养时,体系pH值、细菌数量和酪胺生成量均显著低于其他各处理组;粪肠球菌有很强的产苯乙胺能力而屎肠球菌产苯乙胺能力较弱,当两者混合接种培养时,各混合体系的产苯乙胺水平相当,屎肠球菌产苯乙胺能力不受影响,而粪肠球菌产苯乙胺能力显著降低。

关 键 词:粪肠球菌  屎肠球菌  酪胺  苯乙胺

Abstract:Enterococcus faecalis and Enterococcus faecium are the main β-phenylethylamine and tyramine-producing bacteria.In this study,we cultured Enterococcus faecalis and Enterococcus faecium by different ratio in one medium.During 48hs' cultivation we found that: when the inoculation ratio of Enterococcus faecalis and Enterococcus faecium was 1∶ 9,the pH value,bacteria population and tyramine production were obviously higher than other tested ratios;Enterococcus faecalis has a great capacity for producing β-phenylethylamine while the capacity of Enterococcus faecium was not so great.When Enterococcus faecalis and Enterococcus faecium were inoculated together,the β-phenylethylamine-producing capacity of Enterococcus faecium was not affected while that of Enterococcus faecalis was decreased.
Keywords:Enterococcus faecalis  Enterococcus faecium  tyramine  β-phenylethylamine
