Abstract:Metabolomics is an important branch of systematic biology. It has received great attention around the world, especially in microbiological research field, and new progress has been also made. The metabolomics of lactic acid bacteria has become one of the hottest research topics. This review summarizes the major techniques involved in the research procedures of the metabolomics of lactic acid bacteria, including sample preparation, analysis and identification of metabolites and data analysis. The applications of the metabolomics of lactic acid bacteria are also given based on several typical examples. At the same time, we discussed the potential problems of the metabolomics of lactic acid bacteria, and points out the future of this research.
