Enterobacteriaceae are microorganisms that are generally
considered to have a high decarboxylase activity; consequently,
they have been associated principally with the production of putrescine and cadaverine (Curiel et al., 2011). Durlu-Ozkaya, Ayhan, €
and Vural (2001) observed that the major BA produced by bacteria of this group were cadaverine, putrescine and tyramine in culture medium supplemented with specific amino acids and ground
meat and hamburger. According to Rokka et al. (2004), the formation of BA is related to the amounts of certain microorganisms,
particularly Enterobacteriaceae, which may be part of the original
microbiota in food products or may be introduced by contamination during food processing. Bunkov a et al. (2010) explored the
production of BA by Gram-negative bacteria isolated from poultry
skin and found that Enterobacteriaceae strains were the largest
producers of putrescine and cadaverine. The formation of BA from
Enterobacteriaceae was also observed in other products. Marino,
Maifreni, Moret, and Rondinini (2000) found a positive correlation between the concentration of cadaverine and Enterobacteriaceae counts in cheese; the same bacterial group was
identified by Curiel et al. (2011) as being responsible for the production of putrescine and cadaverine in pig meat.
