Abstract: Research on lactic acid bacterial metabolism has already stepped into a new era. This review summarizes the current research on sugar, citric acid and protein metabolism in lactic acid bacteria, as well as the application of genomics, comparative genomics and metagenomics based on next-generation sequencing technology in studies of lactic acid bacterial metabolism. It is expected that this review will provide theoretical support for further research of lactic acid bacterial metabolism.

Key words: lactic acid bacteria, sugar metabolism, citric acid metabolism, protein metabolism, genomics

摘要： 乳酸菌代谢研究已进入一个新的时代，本文主要阐述目前乳酸菌在糖代谢、柠檬酸代谢及蛋白质代谢等方面的研究，以及基于下一代测序技术的基因组学、比较基因组学和宏基因组学等技术手段在乳酸菌代谢研究中的应用，旨在为现代乳酸菌代谢研究提供理论支持。
