Article Description

In this paper, the sterilization of surfactin and iturin to Salmonella enteritidis was observed, and the optimization of the inactivation of surfactin and iturin to S. enteritidis in meat by a response surface methodology was studied. Results showed that surfactin and iturin had high sterilization to S. enteritidis, whose minimal inhibitory concentration was 6.25 and 12.50 μM respectively. The optimization result indicated that S. enteritidis could be inactivated by five orders of magnitude when the temperature was 4.83°C, the action time was 17.20 h, and the concentration (surfactin/iturin molar ratio 1:2) was 0.69 MIC. © 2008 Springer Science+Business Media, LLC.
