Metagenomic DNA extraction and subsequent bioinformatic analysis is an easy method to analyse the divergence and relative abundance of microflora present in environment samples. Extraction of DNA from faeces of elephant is challenging due the presence of inhibitory substances in dung. DNA was extracted from faeces using cTAB lysis method and commercial kits. The V3-V4 region of 16S rRNA was amplified and was further used for library preparation using NEBNext® Ultra™ DNA Library Prep Kit for Illumina®India. Taxonomic analysis was done using V search against SILVA data base. Metagenomic analysis revealed that Bacteriodata, Verrucomicrobiota, Firmicutes, Spirochaetota, Fibrobacterota, Synergistota, Proteobacteria were the major phyla seen in elephant dung samples.
