Treatment with CFS reduced the area of the three identified peaks. In both microorganisms, the greater reduction was observed in the peak corresponding to cell envelope (C). These results are in concordance with Martinez, Rodriguez, and Suarez (2000), who report that once bacteriocins enter to a cell, through the pores formed in the cell membrane, may affect the DNA and RNA.
The joint use of CFS with chitosan and SL produced strong changes in L. innocua and S. putrefaciens thermograms. Regarding to L. innocua, the reduction of peaks A and B was greater than 90%, while peak C could not be detected. In the case of S. putrefaciens, peaks A and C could not be detected, and peak B showed an increase of its area. Considering the range of temperature of the latter peak, there may be an overlap between peaks B and C, which could justify the increase of enthalpy released.
