The primer pair used for amplification of the bacterial 16S rDNA was 27f and 1492r (Eden et al. 1991). The partial sequence of the 16S rRNA gene was analyzed using the NCBI BLAST tool for similarity comparison. Alignment of 16S rRNA genes from J12 and GenBank database was performed using the CLUSTAL W program. The unrooted tree was built by the Neighbor Joining method.
