LAB that possessed strong antifungal activity and several LAB
that did not have antifungal activity were selected for identification
by sequence analysis of 16S rDNA (Str€om, Sj€ogren, Broberg, &
Schnürer, 2002). The LAB were grown overnight in MRS broth
anaerobically at 30 C and subsequently centrifuged to obtain the
bacteria cell pellet. Bacteria DNAwas extracted using the previously
described method (Prasad & Turner, 2011). Amplification of the 16S
rDNA gene was done by polymerase chain reaction (PCR) (94 C for
2 min, and 30 cycles of 94 C/20 s, 53 C/30 s, 72 C/1.5 min) using
primers 16S-S Forward (50-AGAGTTTGATCCTGGCTC-30) and 16S-R
Reverse (50-CGGGAACGTATTCACCG-30). The resulting PCR products
were sent for purification and sequencing at Macrogen (South
Korea). The partial 16S rDNA sequences of approximately
250e500 bp were used to search public databases (Genbank using
BLAST and the Ribosomal Database Project) for the identification of
the LAB with the closest species match being reported.
