Advance in molecular identification techniques on the classification and identification of lactic acid bacteria in dairy products

This paper summed up Molecular identification techniques for Classification and identification of Lactic acid bacteria in dairy products, and especially introduced DNA fingerprinting technology, molecular marking technology based on rDNA sequences, Species-specific PCR and others used in identification and diversity research in lactic acid bacteria in dairy products. The principles, methods and application in recent years of these technologies were also introduced. The developing of Molecular identification techniques have been provided some new and dependable methods for Classification and identification of Lactic acid bacteria. For threshold and sharpness of separation are different for each method, people should choose suitable method or acombination ofphenotypic and physiological characteristics according to their purposes.
