The crude extract and its CF and EF fractions that showed
antibacterial activities against Gram-positive bacteria were
evaluated for its MIC. Results reveal a weak antibacterial
activity against the bacteria tested since the MIC obtained for
all extracts was >5 mg/mL, except for B. subtilis USTCMS 1011
whose MIC is 5 mg/mL for CF and EF fractions (Table 2).
