The major technical development was the deployment in many centers of next-generation DNA sequencing technologies with greatly enhanced capabilities for sequencing collections of microbial genomes in the metagenome. Technological advances have created new opportunities for the pursuit of large-scale sequencing projects that were difficult to imagine a decade ago.
Our 16S rRNA gene phylogenies, including sequences from metagenome studies, identified many free-living bacteria from open-ocean environments that fell within the sulfur- and methane-oxidizing symbiont clades, in contrast to previous studies that identified only a few free-living bacteria in each Glade.
In this study, we explored the bacterial metagenome of commercially available cigarettes using a 16S rRNA-based taxonomic microarray, as well as traditional cloning and sequencing methods, to better understand bacterial diversity of these widely used products.
The present study aimed at accessing the metagenome of panchagavya to understand bacterial diversity using DGGE a culture independent technique.

To investigate the relationship between obese and gut microbiome functions, we predicted the potential metagenomes from the community profiles of normalized 16S rRNA genes with PICRUSt [14].
The taxonomy of the aligned reads was parsed by using the MEGAN4 MetaGenome Analyzer (7).
The rumen metagenome profile included the counts of reads that aligned to each contig, which could be analyzed using metagenomic tools and correlation plots.
