n -Butanol tolerance of the strains IMI218 (containing the rpn4-1 allele) (▲), IMI238 (containing the rtg1-1 allele) (◊), CEN.PK113-7D (□) and the evolved strain IMS0344 (●). The data represent the average and the standard deviation of the biomass yield (OD660) measured after 48 h from at least 16 independent cultures in presence of different concentration of n-butanol.
