This article begins with an introduction to malolactic fermentation in wine, followed by a review of the occurrence of arginine degradation in wine lactic acid bacteria and the pathway of arginine catabolism, the distribution of enzymes responsible, and the formation of products. The bioenergetics of wine lactic acid bacteria and arginine degradation are then reviewed. This is followed by a review of the possible mechanisms of arginine transport, and regulation of arginine metabolism and synthesis of the enzymes for arginine catabolism. Finally, the practical significance of arginine metabolism in wine lactic acid bacteria is reviewed with respect to taxonomic utility, biological significance and oenological implications.
