Abstract
Several bacterial strains were isolated from wild and reared fish and shellfish. The identification of these strains showed the dominance of the
species in all seafood samples, followed by
spp.,
,
,
,
and
. The isolates were studied for their ability to produce exoenzymes and biofilms. The chemical composition of the essential oils from
leaves,
rhizomes and
aerial parts was studied by GC and GC/MS. The essential oils' antioxidant and antibacterial activities against the isolated microorganisms were studied. Low concentrations of the three essential oils were needed to inhibit the growth of the selected bacteria and the lowest MBCs values were obtained for the laurel essential oil. The selected essential oils can be used as a good natural preservative in fish food due to their antioxidant and antibacterial activities.
