Summary

Based on the deterioration of three substrates (histidine, TMAO and the muscular proteins of the sardine), the effect of bacteria on deterioration of sardines stored at low and medium temperature is examined. Enterobacteriaceae, a flora of hygienic interest, significantly affects the deterioration of sardines stored at ambient temperature. Shewanella putrefaciens is the main bacterium responsible for sardine deterioration. As a result of changes to the isolating medium, the authors have indicated that Acinetobacter-Moraxella may also be responsible for deterioration of iced sardine. These data show that the flora responsible for sardine deterioration is mesophilic, psychrotrophic; note the short storage life of the iced sardine (6 to 9 days).
