METHOD FOR DETERMINING LACTIC ACID BACTERIAL SPECIES

摘要

The invention relates to a method for rapidly determining lactic acid bacterial species that are important as dairy starters or in probiotic use. The method is based on indicating the nucleic acid sequence characteristic of the bactrial species to be determined with a specific oligonucleotide or a pair of oligonucleotides. The species-specific oligonucleotides identifying the 16S-23S rRNA spacer region are described for the lactic acid bacterial species Lactobacillus delbrueckii, Lb. (para casei, Lb. acidophilus, Lb. helveticus and Streptococcus thermophilus.
