Performance of the Saccharomyces cerevisiae mutant strains and WT strain tolerant to high-concentration furfural stress. A The furfural tolerance of the four mutant strains and WT strain was observed by plate dot; B growth curves of the mutant and wild-type strains in YPD medium containing 3.5 g/L furfural. The results shown are the average of the three experiments. WT, wild-type; YPD, yeast extract peptone dextrose
