Antimicrobial activities of Zataria multiflora (Avishan Shirazi)against some feed-borne bacteria

Essential oil reduces the risk of growth of pathogenic or spoilagemicroorganisms both in food and feed products due to their chemicalcompound. In this study, the antimicrobial effect of Zataria multifloraBoiss essential oil (ZMEO) (۰, ۰.۳, ۰.۴۵, and ۰.۶ %v/v) evaluated at ۴ °Cfor ۱۵ days against Enterobacteriaceae (EBC) and Total ViableCount(TVC).The results of gas chromatography–mass spectrometry analysis showedmajor components of the ZMEO were carvacrol (۷۳.۶۵%), thymol(۴.۳۱%), Trans-caryophellene(۲.۹۳ %), and Gamma-terpinene (۲.۲۷%).The other compounds were linalool (۱.۲۸%), thymol methyl ether(۰.۶۲%), carvacrol terpinene-۴-ol (۱.۷%), and ۱, ۸- cineole (۰.۵۲).Antimicrobial analysis indicated that ZMEO successfully inhibited thegrowth of EBC and TVC until ۱۵ days. The results showed that byincreasing the concentration of essential oil inhibition was increasesignificantly (P<۰.۰۵)The results of this study show that ZMEO can be a promising candidatefor extending the shelf life of Feed and Food products during chilledstorage.
