Citrate and sugar cofermentation in Leuconostoc oenos, a 13C nuclear magnetic resonance study
Article Abstract:
The cofermentation of citrate and glucose in growing and nongrowing cultures of the wine lactic acid bacteria, Leuconostoc oenos, diverts glucose molecules to ATP-producing pathways and allows reoxidation of NAD(P)H by additional pathways. 13C nuclear magnetic resonance spectroscopy shows that the end product of the cofermentation is acetate. A large decrease in the concentration of glucose-6-phosphate is seen during cofermentation. The carbon from citrate forms lactate and 2,3-butanediol, and glucose forms acetate. The metabolism of only citrate produces acetoin, and of glucose produces ethanol, glycerol and erythritol.

Glucose metabolism and kinetics of phosphorus removal by the fermentative bacterium Microlunatus phosphovorus
Article Abstract:
Research was conducted to examine the phosphorus and carbon metabolism in Microlunatus phosphovorus using a batch reactor to investigate the kinetics of uptake and extracellular compounds in combination with 31P and 13C nuclear magnetic resonance. Repetitive anaerobic and aerobic cycles were carried out to induce phosphorus release and uptake in a sequencial batch reactor. M phosphovorus' contribution for phosphorus removal in wastewater treatment plants is described.

Engineering Lactococcus lactis for production of mannitol: highyields from food-grade strains deficient in lactate dehydrogenase and the mannitol transport system
Article Abstract:
The construction of L. lactis strains able to form mannitol as an end product of glucose metabolism is described. Mannitol is a six-carbon sugar polyol, and is synthesized by many eukaryotes and a few bacteria, but apparently not by archaea.
