The dominant micro biota (Bacillus sp) was genomically identified by 16SrRNA
sequencing.
To these 100 nano grams of genomic DNA which was extracted from the Bacillus sp and the 16S rRNA gene was amplified using the universal primer with the standard PCR protocol.
The PCR products were purified by a Gel extraction kit (Medox Biotech India Pvt. Ltd)and sequenced (Amnion Biosciences, Bangaluru, India).
The nucleotides of the 16SrRNA sequence were matched with the other microbes in the NCBI database using the BLAST
program. The construction of phylogenetic tree was carried out by Geneious Basic software and evolutionary history inferred using the neighbor joining method (Sneath and Sokal, 1973).
