MIC of chloramphenicol were 0.31–1.25 g/ml against bacterial
strains tested (Table 3). MIC of ferulic acid (Table 3) was 750 g/ml
against gram positive bacteria (two strains of S. aureus and L. monocytogens ATCC 7644). S. enterica ATCC 13076 was more resistant
to ferulic acid with MIC of 1500 g/ml (Table 3).
. Ferulic acid is a
major phenolic acid in various date fruits (Mansouri et al., 2005;
Benmeddour et al., 2013). It is used as a food additive for its antimicrobial
and antioxidant activities. L. monocytogenes, S. enterica, and
E. coli O157:H7 exhibited sensitivity to ferulic acid (Takahashi et al.,
2013).
