Origin of end-products from the co-metabolism of glucose and citrate by Leuconostoc mesenteroides subsp. cremoris

Summary The addition of citrate to glucose broth led to an increase in specific growth rate and glucose catabolism, but a decrease in molar growth yield from glucose, in Leuconostoc mesenteroides subsp. cremoris. Acetate and formate were produced during the stationary phase of growth. According to the fermentation balance, part of the acetate and lactate came from the pyruvate of citrate metabolism. L. mesenteroides subsp. cremoris incorporated radioactive metabolites from 1,5-¹⁴C] citrate into cell material, primarily into lipids. U-¹⁴C] Glucose was not incorporated into cell material.
