Production of AP-3 with isobutanol added at various concentrations and different cultivation times. a Structures of ansamitocins; b effect of isobutanol supplementation on AP-3 production. 50 mL of optimized medium was loaded in a 250-mL flask and cultured at 28 °C with a shaking rate of 220 rpm. Isobutanol was added at one of three different final concentrations (18, 36, or 54 mM) at 0 h, 24 h, 48 h, or 72 h of cultivation
