title: Detection of dairy Leuconostoc strains using the polymerase chain reaction.
abstract: This paper reports the design of a Leuconostoc-specific oligonucleotide based on 16S rRNA sequence data. When this oligonucleotide was used in a polymerase chain reaction (PCR) in conjunction with an oligonucleotide to a conserved region of the 16S rRNA sequence, a Leuconostoc-specific PCR product of approximately 470 bp was produced. The use of a second oligonucleotide to a conserved region allowed the production of an approximately 350 bp product in all PCRs, acting as a positive control. The PCR procedure described was particularly useful for detecting the presence of Leuconostoc in mixed mesophilic starter cultures. The Leuconostoc-specific oligonucleotide was used also as a specific hybridization probe.
