PCR amplification and sequencing of 16S rRNA gene
Genomic DNA from freshly grown culture of strain SJ-101
was isolated and purified by a cetyltrimethylammonium
bromide (CTAB) miniprep procedure [12]. Total genomic
DNA (50 ng) was used as a template for amplification of
16SrRNA gene employing primers, fD1 (5’-
AGAGTTTGATCCTGGCTCAG-3’) and rD1 (5’-
AAGGAGGTGATCCAGCC-3’) complementary to the 5'
and 3’ regions of eubacterial 16S rRNA genes,
respectively. The amplicon was gel purified using a Gel
Extraction kit (Qiagen, USA) and sub-cloned into pGEMTEasy
vector (Promega, USA). The selected clone was
subjected to sequencing of 16SrRNA gene fragment with
SP6 and T7 sequencing primers using ABI prism 3730
sequencer.
