Changes in the intracellular MDA and mitochondrial membrane potential of four mutant strains and the WT strain under furfural stress. a Intracellular MDA content of the four mutant strains and WT strain under furfural stress at 0 and 3 h (the results shown are the average of the three experiments); b and c changes in the intracellular MMP of four mutant strains and the WT strain under furfural stress at 0 and 3 h. MDA, malondialdehyde; WT, wild-type; MMP, mitochondrial membrane potential
