Verification of citric acid production of transformants by the shake flask fermentation and Ring diameter ratios. A Verification of citric acid production of transformants (20-15, 20-16, 20-25, 20-27, 20-29, 21-8, 21-28 and 21-32) by the 50 mL shake flask fermentation; B Ring diameter ratios determination of transformants (20-15, 20-16, 20-25, 20-27, 20-29, 21-8, 21-28 and 21-32) by transparent halo zone on CM + CaCO3 medium. CA yield with different letters differ significantly (abcd, P < 0.05)
