Analysis of changes in ROS in Saccharomyces cerevisiae cells under furfural stress via flow cytometry. a The growth ability of the four mutant strains and WT strain under 1.0 mmol/L hydrogen peroxide stress; b and c change in the ROS in the cells of the four mutant strains and WT strain under furfural stress at 0 and 3 h; d the proportion of dead cells in the four mutant strains and WT strain under furfural stress for 3 h. The results shown are the average of the three experiments. ROS, reactive oxygen species; WT, wild-type
