The adenosine triphosphate (ATP) content (A) and mitochondrial network morphology (B) in the wild-type (WT) strain, Δsod1 and Δsod2 mutants cultivated in medium with 3% glycerol or different glucose concentration. Data are presented as mean ± SD from three independent experiments. * p < 0.05, ** p < 0.01, *** p < 0.001 as compared to the WT strain; a—different from medium with 3% glycerol, b—different from medium with 0.5% glucose, c—different from medium with 2% glucose, d—different from medium with 4% glucose. The microscopic images present the typical results of the duplicate experiment.
