3.4. Determination of MIC and MBC
MIC of crude extracts ranged from 1.46 mg/mL to 2.52 mg/mL against Gram positive bacterium (S. aureus). In Gram negative bacterium such as E. coli MIC ranged from 1.84 mg/mL to 2.82 mg/mL. Among the 11 crude extracts tested the results of MBC ranged from 2.92 to 7.56 mg/mL against S. aureus and for E. coli, MBC ranged from 3.80 to 8.46 mg/mL
