Fig. 2From: 5-Aminolevulinic acid fermentation using engineered Saccharomyces cerevisiaeALA production by the S. cerevisiae HEM1-overexpressing strain and the control strain. a Cell concentration (g-cell/L); b intracellular ALA content (mg/g dry cell weight [DCW]); c volumetric ALA concentration (mg/L). Gray and black bars represent values after cultivation for 24 and 48 h, respectively. The values are presented as means, with error bars showing SD (n > 3). p-values are represented when they show statistically significant differences among the engineered strains by Student’s t test (p < 0.05, analysis of variance)Back to article page
