RESUMO

Thyme [Zataria multiflora Boiss.] is one of the Iranian traditional spices and it has antimicrobial effect on the pathogenic bacteria which are agents for some current food borne intoxications. The aim of this study was to evaluate the antimicrobial activity of Zataria multiflora Boiss. essential oil on V. parahaemolyticus in salted [8% Nacl in tissue] silver carp. Effect of different concentrations of this Essential oil [0.0%, 0.045%, 0.135%, 0.405%, 0.810%] on behavior of V. parahaemolyticus in two temperatures [15, 25 C] was determined by evaluation of the bacterial growth in salted fish fillets. The essential oil in used concentrations had significant inhibitory effect on the growth of V. parahaemolyticus in salted fish compare with control treatment during the storage time [p<0.05]. There was no significant difference between all treatments. The results showed that Zataria multiflora Boiss. Essential oil had inhibitory effect on V. parahaemolyticus, therefore it can be considered as a natural preservative in salted fish

RESUMO

There is increasing demand for use of natural preservatives such as bacteriocins to control foodborne pathogens in seafoods. This study was performed to evaluate the antimicrobial effects of Nisin on Staphylococcus aureus in light and heavy salted silver carp fillets [4 and 8% NaCl]. Effect of different concentrations of Nisin [0, 0.15, 0.25, 0.75, 1.5 micro g/ml] on behavior of S.aureurs at unfavourable refrigeration storage temperature [10 [degree sign]C] was determined by evaluation of the bacterial growth in salted fish fillets. The results showed that used concentrations of Nisin had inhibitory effect on the growth of S.aureus in light and heavy salted fish fillets compared to the control [p<0.05]. This study showed inhibitory effect of Nisin on the growth of S.aureus. Therefore it can be considered as a natural preservative in light and heavy salted fish
