Figure Lengend Snippet: Inhibition zones of various extracts tested against Escherichia coli ■ , Bacillus megaterium ■ , and Bacillus subtilis ■ . Inhibition zones are expressed as a percentage relative to vancomycin (positive control), normalized to its inhibition zone. Positive values indicate a greater effect, and negative values signify a weaker effect than vancomycin. The absence of the bar indicates no difference compared to the negative control (only 300 µL of an aqueous solution containing 5% Tween-20 and 10% DMSO).
Article Snippet: The agar well diffusion method and broth dilution method were used to assess the antimicrobial activity of the extracts against Escherichia coli (ATCC BAA-1025-B1) (American Type Culture Collection, Manassas, VA, USA), Bacillus megaterium (ATCC 14581) (American Type Culture Collection, Manassas, VA, USA), and Bacillus subtilis (ATCC 6051) (American Type Culture Collection, Manassas, VA, USA).
Techniques: Inhibition, Positive Control, Negative Control
