摘要: Summary The aim was to monitor production of eight biogenic amines (BAs) (histamine, tyramine (TYR), tryptamine, putrescine, cadaverine (CAD), phenylethylamine, spermine and spermidine) by selected 81 lactic acid bacteria (LAB) strains: Lactobacillus, Lactococcus, Leuconostoc, Enterococcus, Pediococcus, Tetragenococcus Bifidobacterium. The tested LAB bifidobacteria were isolated from dairy products beer. decarboxylase activity the micro-organisms studied in growth medium after cultivation. monitored HPLC pre-column derivatisation with dansylchloride. Fifty showed activity. Thirty-one strains produced low concentrations CAD (≤10 mg L−1). Almost 70% beer isolates generated higher amounts TYR (≤3000 mg L−1). Most demonstrated above can contribute increase content BAs or thereby threaten food safety health consumers. Production even representatives some probiotic (Bifidobacterium Lactobacillus rhamnosus) detected this research. This study has also proved that contaminating act as sources
