Production of Biogenic Amines by Lactic Acid Bacteria Isolated from Uzicka Sausages

The aim of this study was to monitor production of seven biogenic amines (Cadaverine – CAD, Putrescine – PUT, Spermine – SPE, Spermidine – SPD, Histamine – HIS, Tyramine – TYR and Tryptamine – TRY) in selected 24 lactic acid bacteria (LAB) strains. The decarboxylase activity of the microorganisms was studied in growth medium after 24 h cultivation. The ability of 24 LAB isolates cultivated in MRS broth and M17 broth supplement with 0.5% glucose to produce biogenic amines was assessed using liquid chromatography tandem mass spectrometry (LC-MS/MS). The investigation showed that LAB isolated from Uzicka sausage are not significant producers of biogenic amines in vitro.
