Figure 2. Primary and confirmatory screening for antimicrobial activities produced by WDF against S. aureus, E. coli and C. albicans.

Figure 2.

Examples of bioassay plates of wood-decaying fungi (WDF) extracts showing growth inhibition zones for S. aureus ( A) and C. albicans ( B) with streptomycin and cyclopirox olamine control antibiotics, respectively. Venn diagram showing the antimicrobial activities detected in the primary screen for 54 WDF extracts ( C) and confirmatory screen for 40 WDF extracts ( D). The frequency and potency of antimicrobial activity against S. aureus and C. albicans for the primary screening of the 54 WDF extracts ( E). NSAM, non-selective antimicrobial activity; BSAB, broad-spectrum antimicrobial; SG+, selective antibacterial activity against Gram-positive S. aureus; SAF, selective antifungal activity against C. albicans; SG-, selective antibacterial activity against Gram-negative E. coli.
