Table 1shows MICs and MBCs obtained in the antimicrobial test.
As can be seen, LAE is a stronger antimicrobial against all bacteria
tested since MIC values were between 100 and 12.5 mg/L.
P. aeruginosa was the most resistant bacteria with MICs and
MBCs from 4- to 8-fold higher than for the other bacteria.E. coli, L.
innocua and S. enterica showed a similar susceptibility with
a maximum difference of 2-fold dilutions.
According to the data fromTable 1, LAE exhibit a bactericidal
effect (MBC/MIC¼1) for all bacteria except againstS. aureus, since
the ratio MBC/MIC was higher than one.
In order to determine the influence of inoculum size in the
antimicrobial activity, MICs and MBCs were determined against
