Table 3.
Observed bioactivities (%) of crude extracts from non-Penicillium strains at 100 µg/mL concentration. Quorum sensing (QS) and biofilm inhibition were compared to growth inhibition of their associated microorganisms, A. fischeri and Ps. aeruginosa, separated by /. Positive control. A: 10 µM 5-(bromomethylene)-2H(5H)-furanone, B: 10 µM chloramphenicol, C: 10 µM polymyxin B.
| Medium | Inhibition (%) of A. fischeri QS/Growth Inhibition |
