The PCR product was purified using a QIAquick PCR purification kit (Qiagen) and ligated into the pGEM-T Easy vector (Promega), according to the manufacturers’ instructions. The ligation product was transformed into competent Escherichia coli JM109 cells. The cloned 16S rRNA gene sequence was analysed with an automated sequencer (ABI 3730XL, Applied Biosystems) at Solgent (Daejeon, Korea). An almost-complete 16S rRNA gene sequence (1519 bp) of strain CNU040T was obtained.
