4. Conclusions
From the results obtained in this study, it can be concluded that mundticin KS produced by E. mundtii Tw56, strain isolated from O. platensis intestine, exhibited a broad spectrum of activity being able to act on Ps. aeruginosa and S. putrefaciens. In consequence, it could be used as an additional hurdle in the preservation of minimally processed fish and/or other sea products. The combination of the bacteriocin with chitosan and SL induced a synergic action on L. innocua and S. putrefaciens inhibition. Mentioned action can be linked with strong changes produced on cellular components as it was demonstrated by DSC. The studies about the effect of the bacteriocin in combination with chitosan and SL in fish are in progress in order to confirm their ability to control bacterial growth.
