5.1.3 Antibacterial activity screening <strong>an</strong>d MIC determination<br />
A total <strong>of</strong> 73 bacterial strains were tested for <strong>an</strong>tibacterial activity using <strong>the</strong> microtitre<br />
plate assay <strong>an</strong>d <strong>the</strong> agar dilution assay. Thirty-two <strong>of</strong> <strong>the</strong> bacterial strains were<br />
Gram-positive <strong>an</strong>d 41 strains were Gram-negative. All 73 bacterial strains were<br />
initially screened for <strong>an</strong>tibacterial activity with <strong>the</strong> respective <strong>an</strong>tibacterial assays<br />
before <strong>the</strong> determination <strong>of</strong> <strong>the</strong> MIC’s <strong>of</strong> <strong>the</strong> pl<strong>an</strong>t extracts.<br />
Fifty-eight bacterial strains were screened with <strong>the</strong> microtitre plate assay <strong>an</strong>d 15<br />
bacterial strains were screened with <strong>the</strong> agar dilution assay. Table 6 indicates <strong>the</strong><br />
