Effect of cyclopropane fatty acid presence in cell membranes on the cellular physiological performance of yeast strain C20 compared with control and H20 which lack the unusual fatty acid. a Comparison of cell growth by OD₆₀₀ nm and fatty acid profile of the cell-membrane phospholipid at 72 h post-induction; UFAs, unsaturated fatty acids; CFAs, cyclopropane fatty acids, b comparison of time course of percentage of CMI (cell-membrane integrity), c relative ROS level at 24 h and 72 h, the ROS level of control at 24 h was normalized to 1, d relative Δψm level at 24 h and 72 h, the Δψm level of control at 24 h was normalized to 1. *p < 0.05 (Student’s t test: two-tailed, two-sample equal variance)
