Germination of Beauveria bassiana was observed at × 400 magnification and in vitro assay of Enterobacter soli (b), Pseudomonas protegens (c) and Serratia marcescens (d) antifungal activity. Coculture bacteria of E. soli (f), P. protegens (g) and S. marcescens (h) and B. bassiana on PDA plates for 3 days. Inhibition was scored as the presence/absence of a distinct zone around inoculation hole. a and e showed the germination and culture of B. bassiana without bacteria. i Germination rate on PDA medium at 28 °C of B. bassiana germ tube under different bacteria coculture conditions and (j) bacteria antifungal units (= [inhibition diameter-5] × 10). Scale bars represent 20 μm (for ad) and 10 mm (for eh)
