A relationship between the amplification of a 500 bp fragment, the enzymatic activity and the amine production was observed. Wines for which the PCR detection was negative never contained histamine. While those carrying HDC+ bacteria, always contained histamine in varying amounts. All the HDC+ strains belonged to the Leuconostoc oenos (oenococcus oeni) species. Moreover, study of HDC activity and colony-forming ability as a function of storage duration showed that even when cultivable population was no more detectable, the histidine decarboxylase activity remained. Histamine and other biogenic amines could be produced during wine aging.
