Co‐metabolism of citrate and glucose by Leuconostoc spp.: effects on growth, substrates and products

Cogan, T. M.·1987·Journal of Applied Bacteriology

Abstract

Growth, substrate utilization and product formation from glucose, citrate and a mixture of both substrates were studied in four strains of Leuconostoc spp. Citrate was not used as an energy source but was rapidly metabolized when glucose was present. The predictable amounts of D‐lactate and ethanol were produced from glucose, although strains X2 and 7–1 gave lower yields of ethanol. In strains NCW1, S3 and X2, co‐metabolism of both glucose and citrate resulted in stimulation of growth, decreased uptake of glucose, increased acetate and D‐lactate production and lack of ethanol production compared with that obtained with glucose alone. Strain 7–1 showed only growth stimulation and increased acetate production. Diacetyl, acetoin or 2, 3‐butylene glycol were not detected. In strain NCW1 citrate had a slightly inhibitory effect on the enzymes of the ‘ethanol’ leg of glucose metabolism. Except for strain 7–1, these observations are consistent with a switch in glucose metabolism from ethanol to acetate production.

  • Theoretically, 1 mol of citrate produces 1 mol of acetic acid, 2 mol of carbon dioxide and 0.5 mol of a mixture consisting of diacetyl, acetoin and 2,3-butanediol.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
