Comparison of N402 (wt) and the ΔfwnA strain (MA93.1) in duplicate maltose-limited retentostat cultures. (A) Pictures of the bioreactor vessel showing the progressive pigmentation of the culture broth of both strains. (B) Biomass accumulation in cultures of N402 (▪) and the ΔfwnA strain (□) and in the effluent of N402 (•) and the ΔfwnA strain (○). (C) Accumulation of total solute carbon in N402 (▪) and the ΔfwnA strain (□) and melanin accumulation in N402 (•) and the ΔfwnA strain (○) in the culture broth. The cultivation results for MA93.1 are compared to N402 from previous data obtained under identical culture conditions (22). The two vertical dashed lines indicate the first observation of conidiophores and the subsequent commitment to conidiation in cultures of N402.
