| Abstract |
|
The antibacterial effects
of three concentrations of Mentha longifolia essential oil on the
growth of Lactococcus garvieae were studied in fillets of rainbow
trout at temperature of 4ºC for 18 days. Although no significant
difference was found in bacterial count in different groups immediately
post-inoculation, significant difference was observed in growth of L.
garvieae between treatments with M. longifolia essential oil
and control group during the experiment (P<0.05).
The most antimicrobial effect was observed in the fillets containing 80
µg/g M. longifolia essential oil. The obtained results indicated
that M. longifolia essential oil at the concentration of 80 µg/g
is suitable to inhibit the growth of L. garvieae in rainbow trout
fillet stored at 4°C.
