Abstract: The rapid identification of lactic acid bacteria, which are essential microorganisms in the food industry, is of great significance for industrial applications. The identification of lactic acid bacteria traditionally relies on the isolation and identification of pure colonies. While this method is well-established and widely used, it is not without limitations. The subjective judgment inherent in the isolation and purification process introduces potential for error, and the incomplete nature of the isolation process can result in the loss of valuable information. The advent of next generation sequencing has provided a novel approach to the rapid identification of lactic acid bacteria. This technology offers several advantages, including rapidity, accuracy, high throughput, and low cost. Next generation sequencing represents a significant advancement in the field of DNA sequencing. Its ability to rapidly and accurately identify lactic acid bacteria strains in samples with insufficient information or in the presence of multiple lactic acid bacteria sets it apart as a valuable tool. The application of this technology not only circumvents the potential errors inherent in the traditional method but also provides a robust foundation for the expeditious identification of lactic acid bacteria strains and the authentication of bacterial powder in industrial applications. This paper commences with an overview of traditional and molecular biology methods for the identification of lactic acid bacteria. While each method has its own advantages, they are not without limitations in practical application. Subsequently, the paper provides an introduction of the principle, process, advantages, and disadvantages of next generation sequencing, and also details its application in strain identification and rapid identification of lactic acid bacteria. The objective of this study is to provide a comprehensive and reliable basis for the rapid identification of industrial lactic acid bacteria strains and the authenticity identification of bacterial powder.
