Authentication method of dairy products

摘要: FIELD: chemistry. SUBSTANCE: group of inventions relates to biotechnology. A method for identifying the presence or absence a lactic acid bacterial strain comprising an IS element in dairy product. The comprises obtaining nucleic sample from product, providing primer pair specific region said uniquely located and sequence adjacent element, performing PCR amplification reaction with pair, by detecting is Pediococcus acidilactii under accession DSM 22981 first SEQ ID NO: 1 second 2 and/or Lactobacillus delbrueckii subsp.lactis No 24025, sixth 6 seventh 7. strains may be used marking products. Proposed are new strains, their use production products as well containing these strains. kit detection strain, pair. EFFECT: provides fast efficient identification 15 cl, ex
