Production of biogenic amines by lactic acid bacteria and bifidobacteria isolated from dairy products and beer

Popis výsledku v původním jazyce

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 and Bifidobacterium. The tested LAB and bifidobacteria were isolated from dairy products and beer. The decarboxylase activity of the micro-organisms was studied in growth medium after cultivation. The activity was monitored by HPLC after the pre-column derivatisation with dansylchloride. Fifty LAB showed decarboxylase activity. Thirty-one strains produced low concentrations of CAD (méně než 10 mg L-1). Almost 70% of beer isolates generated higher amounts of TYR (méně než 3000 mg L-1). Most of the tested LAB demonstrated decarboxylase activity. The above micro-organisms can contribute to the increase of content of BAs in dairy products or beer and thereby threaten food safety and
