Effect of the ADE genes overexpression on intracellular adenine-nucleotide pool. Samples of the recombinant strains and control strain BHO were harvested at exponential phase for determination of energy charge (a), ATP concentration (b), total AXP content (c), and IMP concentration (d), respectively. CK represents under control condition, AC represents the acetic acid stress, and e represents samples were harvested at the exponential phase. Each value represented the mean value of three independent replicates. *p value < 0.05 and **p value < 0.01 in significance analysis using t test
