The production of β-amyrin in the two-stage fed-batch fermentation. A Fed-batch fermentation of strain AC25. The glucose feeding solution is added at 6th h. Green arrow represents the addition of galactose, red arrow represents the supplementation of absolute ethanol, blue arrow represents the end of glucose supplementation and the absolute ethanol was supplemented until the end of the fermentation. B The accumulation of white solids on the tank wall. All values presented are the means of three biological replicates, and error bars represent standard deviations
