Arginine metabolism in wine malolactic bacteria
葡萄酒苹果酸-乳酸菌精氨酸代谢研究概况

Arginine metabolism in wine malolactic bacteria may increase the concentration of ethyl carbamate(EC,a known carcinogen with the potential toxicological effects) in wine,which makes a profound impact on wine hygienic quality.In fact,recent advanced studies have proved that arginine metabolism in wine malolactic bacteria is via arginine deiminase pathway(ADI pathway),and this pathway is composed of three enzymes: arginine deiminase(ADI),ornithine transcarbamylase(OTC),carbamate kinase(CK).The possible mechanisms of arginine transport and the regulation of major enzymes for arginine metabolism as well as the mechanism of ADI pathway and its molecular characteristics are reviewed.The study on arginine metabolism in wine malolactic bacteria has practical and theoretical significance for the safety and high quality of wine.
