Genomic DNA was isolated
using Genomic DNA isolation kit (Chromous Biotech) and this DNAwas further
used for the PCR reaction for the amplification of 16S rRNA gene using bacterial
universal primers for 16S rRNA gene; (i) forward primer: 50-CCGAATTCGTCGACAAC
AGAGTTTGATCCTGGCTCAG-30 and reverse primer: 50-CCCGGGATCCAAGCTTAC
GGCTACCTTGTTACGACTT-30 and (ii) forward primer 27F: AGAGTTTGATCCTGGCTCCAG
and reverse primer 1492R: TACGGTTACCTTGTT ACGACTT.
