From: Phenotypic convergence in bacterial adaptive evolution to ethanol stress
Metabolome analysis of ethanol tolerant E. coli strains under ethanol stress conditions. a Concentration of amino acids in ethanol tolerant strains. In each inset, the vertical axis shows the log-transformed absolute concentration (μM). The blue bar and red bars indicate the data of the parent strain and tolerant strains, respectively. b Correlation between metabolite concentration changes in strains E and F. Horizontal and vertical axes represent log-transformed concentration ratios with the parent strain, and each dot represents the concentration change of the metabolites
