just mixed. In terms of the best NPs, the ones produced with DHBA
had lower EE%, and the higher values were obtained for NPs produced
with LMWC, and for NPs produced with the phenolic compounds
RA and PA. In terms of bioactivity, all NPs tested had
high values of inhibition above all the tested bacteria (60–90%)
with slight differences between them, being slightly better the
ones produced with HMWC. The most susceptible bacteria were
E. coli and B. cereus, while the worst efficiency was obtained for
S. typhimurium. The mechanisms of action of the NPs on the bacterial
cells was shown to be by adsorption of the compounds at the
surface originating in some cases the appearance of holes and surfaces
disrupted and in other cases lysis is also apparent
