SYNTHETIC OLIGONUCLEOTIDE PRIMERS AND METHOD OF DETECTING Lactococcus lactis subspecies lactis IN STARTER CULTURES WHEN PRODUCING FERMENTED MILK PRODUCTS

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to biotechnology and specifically to DNA technologies. Disclosed are synthetic oligonucleotide primers and a method of detecting Lactococcus lactis subspecies lactis in starter cultures when producing fermented milk products. The disclosed method involves conducting a polymerase chain reaction (PCR). Detection of a 449 bps DNA fragment indicates presence of Lactococcus lactis subspecies lactis in the analysed biological material.;EFFECT: method can be used in the milk processing industry to detect and identify strains and cultures of Lactococcus lactis subspecies lactis in starter cultures when producing fermented milk products.;2 cl, 1 tbl
