Portion of 13C NMR spectrum of fermentation medium 2 hours after the addition of uniformly labeled acetate into the anaerobic phase of ALS974 fermentation. S1′′ and S2′′ correspond to the doublet of the CH2 group of succinate; S′ corresponds to the singlet of the CH2 group of succinate; P′ corresponds to the singlet of the CH3 group of pyruvate; A1′′ and A2′′ correspond to the doublet of the CH3 group of acetate; A′ corresponds to the singlet of the CH3 group of acetate; L′ corresponds to the singlet of the CH3 group of lactate; E1′′ and E2′′ correspond to the doublet of the CH3 group of ethanol.
