Selected factors influencing the ability of Bifidobacterium to form biogenic amines

Popis výsledku v původním jazyce

The ability of typical probiotic culture of Bifidobacterium to produce biogenic amines could be considered a contrastive feature to the beneficial dietary effect on human health. The aim of this pilot study was to evaluate the decarboxylase activity of Bifidobacterium animalis subsp. lactis CCDM 239 influenced by selected factors (pH 4.5 and 5.0; the contents of NaCl 0-20.0 g L-1, glucose and lactose 0-10.0 g L-1) at in vitro conditions. The kinetics of the biogenic amine production under the above-mentioned conditions was also monitored. The biogenic amine content detection was carried out in the supernatants of inoculated broth [MRS enriched with amino acids: arginine, ornithine, lysine, tyrosine; 3 g L-1 after the cultivation (48 h, 37 ? 1 °C)]. RP-HPLC after the precolumn derivatisation with dansyl chloride was used. In most cases, the low concentrations of tyramine were monitored (<15 mg L-1). Simultaneously, it was found out that the addition of certain fermentable saccharide con
