Metagenomics is the study of metagenomes, genetic material recovered directly from environmental samples. The broad field was referred to as environmental genomics, ecogenomics or community genomics. Recent studies use "shotgun" Sanger sequencing or next generation sequencing (NGS) to get largely unbiased samples of all genes from all the members of the sampled communities.
16S and 18S ribosomal RNA (rRNA) – Long reads span multiple variable regions, enabling high-resolution species identification (Figure).

CD Genomics offers a complete range of metagenomics solutions:

•  16S rDNA tagging: general taxonomics classification
•  Whole genome metagenomic sequencing
•  Establish microbial gene catalogue
•  Human microbe & related disease association analysis
•  Metatranscriptome survey

Applications:

•     Analyze the relative abundance of microbial species under varying environmental conditions
•     Discover new genes and make functional predictions in unculturable species
•     Perform gene expression analysis and functional annotation within microbial communities
•     Identify novel pathogens in viral outbreaks by sequencing fragments of amplified RNA from infected individuals
•     Take advantage of the long read lengths to generate the most accurate representation of samples

Study diversity in environmental microbial communities using the MiSeq and ion torrent platforms. These Systems have become the standard for RNA identification and whole genome surveys having enabled an unprecedented view of microbial diversity in such environments as the human gut and mouth, soil, coral reefs, deep sea thermal vents, drinking water, and much more.
