However, under conditions of our experiment,
0.1% (w/v) NAc-COS and 0.1% (w/v) COS showed effective antibacterial
activities against S. typhimurium, with COS being the most
effective of the two. While NAc-COS completely inhibited the
growth of S. typhimurium after 6 h of incubation, COS killed all of
the bacteria after only 3 h of incubation
