Fig. 3From: Propionic acid disrupts endocytosis, cell cycle, and cellular respiration in yeastEffect of propionic acid on yeast reduction of MTT. Yeast cells were exposed to propionic acid, nonanal, or a no-compound control, and the reduction of MTT was monitored spectrophotometrically for 9 h. Mean MTT reduction scores are plotted with standard error bars (n = 3)Back to article page
