Chemiosmotic energy from malolactic fermentation.
By using the luciferase-luciferin ATP assay and whole cells of Leuconostoc oenos, we have demonstrated that malolactic fermentation does yield ATP. This energy-yielding mechanism did not occur in a cell extract and was inhibited in the presence of dicyclohexylcarbodiimide or an ionophore such as monensin. A lactate:proton efflux mechanism for this proposed pathway is presented.
