Isolation and characterisation of F. venenatum isolates from additional commercial fermentation samples. (A) Representative colony morphology of WT, C-variant (Cv) and post-fermentation WT (pfWT) isolates after growth on PDA for seven days at 28 °C. (B) Representative hyphal morphology of all batch 2 isolates after growth in PDB for 40 h at 28 °C. Scale bar represents 100 μm. (C) Boxplot of radial growth rate for additional isolates averaged over a five-day period (n = 3). *** p < 0.001
