The cometabolism of citrate and glucose by growingLactococcus lactisssp. lactis bv. diacetylactis was studiedusing a natural-abundance stable isotope technique. By ajudicious choice of substrates differing slightly in their13C/12C ratios, the simultaneous metabolism of citrate andglucose to a range of compounds was analysed. These end-products include lactate, acetate, formate, diacetyl andacetoin. All these products have pyruvate as a commonintermediate.
