FIGURE 1.

Interactions between C. cinerea and bacteria. A, vegetative mycelium of C. cinerea was grown on submerged glass beads in minimal medium. After 60 h, 4 ml of medium was replaced by a suspension of B. subtilis, E. coli, or P. aeruginosa. 0 and 48 h after addition of the bacteria, the plates were photographed. Fungal growth is indicated by the white mycelium. B, bacterial growth was monitored by measuring A₆₀₀ (OD₆₀₀) over 48 h. As controls, bacteria and fungus were grown independently in the beads system. All data points were acquired in three biological replicates and are displayed with the standard deviation. C. cinerea exhibited a bactericidal effect in competition with B. subtilis and was strongly inhibited by P. aeruginosa.
