37 fatty acid production in engineered C. glutamicum with the different expression levels of thioesterases. A, B and C, 37 fatty acid production of engineered C. glutamicum strains with different expression levels of tesA, tesB and te9, respectively.(I) Stacked column chart demonstrating changes in 37 fatty acid titers of engineered C. glutamicum strains with the different expression levels of thioesterases. (II) Heatmap of percentage distribution (% of total fatty acid) of 37 fatty acids in engineered C. glutamicum strains with the different expression levels of thioesterases. (WG: wild-type C. glutamicum; CGtesA, CGtesB, and CGte9: C. glutamicum with overexpression of tesA, tesB, and te9, respectively; CGΔtesA, CGΔtesB, and CGΔte9: C. glutamicum with tesA, tesB, and te9 knocked out, respectively). Different letters for the same fatty acid indicated significant differences (P < 0.05; n = 3). Data without marked letters indicated a nonsignificant difference (ns)
