All the samples, after enrichment were serially diluted in
peptone water (peptone 0.1%, NaCl 0.9%) and plated on the corre-
sponding media and incubated microaerophilically for 48 h.
Genotypic characterization of selected LAB was carried with 16S
rDNA gene sequencing. PCR and DNA sequencing was performed by
MACROGEN Inc. (Korea). The resultant sequences were compared
to sequenced bacteria with a BLAST search using the GenBank/
EMBL/DDBJ database.
