From: Physiological mechanism of improved tolerance of Saccharomyces cerevisiae to lignin-derived phenolic acids in lignocellulosic ethanol fermentation by short-term adaptation

Fig. 7

TEM imagines of S. cerevisiae after treatment of phenolic acids. a the magnified specific parts of yeast strain cells; bd quantification of cell diameter, thickness of cell wall and membrane (measurement of over 50 cells), respectively. PS represents the parental strain cells; control was the control group of adapted strain, which obtained from sequentially transferring and culturing parental strain cells in synthetic medium without phenolic acid at the same condition with Method I; E, I and K were adapted strains from Method E, I and K, respectively. All above strain cells were inoculated in the medium with phenolic acids mixture at concentration of IC75, 30 °C, 150 rpm for 9 h. CW cell wall, CM cytoplasmic membrane, red circle marks mitochondria; red arrow marks cytoplasmic membrane invagination
