I. Geornaras et al., BIOGENIC-AMINE FORMATION BY POULTRY-ASSOCIATED SPOILAGE AND PATHOGENIC BACTERIA, Letters in applied microbiology, 21(3), 1995, pp. 164-166
The production of biogenic amines by 50 poultry-associated bacterial s
trains (25 Pseudomonas, 13 Salmonella and 12 Listeria) was investigate
d on amine agar plates containing lysine, histidine, ornithine, phenyl
alanine, tryptophan and tyrosine. Seventy-four per cent of all the str
ains produced cadaverine and putrescine, while phenylethylamine, hista
mine, tyramine and tryptamine were produced by 72, 56, 34 and 24% of s
trains, respectively. Different patterns of biogenic amine production
amongst the three bacterial genera tested were apparent as well as amo
ngst strains of the same genus. This study highlighted a high incidenc
e of biogenic amine-producing bacterial strains associated with poultr
y.
