Popis: The objective of this study was to design and develop an analytical protocol using chemical and molecular techniques to detect microorganisms able to produce biogenic amines (BAs). The protocol consists of: an initial screening by TLC (Thin Layer Chromatography) to detect BA production by microorganisms; multiplex PCR to identify decarboxylase genes in the BA-positive samples; and HPLC to quantify BA production. The protocol was used to verify the ability of a Lactobacillus hilgardii strain isolated from wine to produce histamine during malolactic fermentation. The results showed that this analytical approach is an useful tool to determine the production of BAs by microorganisms. Commercial dry yeast starters routinely used in wine-making were examined by this protocol and the results showed that the presence of bacterial contamination in these preparations is a possible origin of BAs in wine.
