Fig. 2.

Incorporation of ¹³C-carbon into the amino acids ([M-57]⁺) of SYK-6 after feeding with the following labeled carbon substrates: (A) (1,2-¹³C) glucose and yeast extract; (B) (phenyl-¹³C) vanillin; (C) (1,2-¹³C) acetate; and (D) (U-¹³C) pyruvate*. The asterisk indicates that unlabeled glyoxylate was added to the labeled pyruvate culture to explore the presence of glyoxylate shunt in SYK-6. The SD represents the 2% technical error of the instrument. The Embden–Meyerhof–Parnas pathway is shown in purple; the TCA is shown in green; the PPP is shown in red; and the amino acid synthesis pathway is shown in black.
