Carotenoid (A–C), CoQ₁₀ (D), and PDC (E) levels in N. aromaticivorans PDC strains grown in sorghum APL. Filled circles show data for PDC-producing strains, open squares show data for non-PDC-producing strains grown in sorghum APL reproduced from Fig. 4. The amounts of carotenoids and are reported as mass normalized to dcw. PDC levels are reported as concentration measured in the media. An asterisk (*) denotes PDC strain data that are significantly different from the 12444 parent strain data (Student’s t-test, P < 0.05).
