What is metagenomics and why are we using metagenomics analysis?

Metagenomics provides access to the functional gene composition of microbial communities and thus gives a much broader description than phylogenetic surveys, which are often based only on the diversity of one gene, for instance the 16S rRNA gene.

What are the principles of metagenomics?

Metagenomics, the principle of which relies on the genomic analysis of a sample from a complex environment containing more than one microorganism, provides a view of the composition of this sample. Metagenomic studies became increasingly accessible with the advent of Next Generation Sequencing (NGS) [4].

How are metagenomic sequences annotated?

Metagenome functional annotation is very similar to genomic annotation and relies on comparisons of predicted genes with existing, previously annotated sequences. The goal is to propagate accurate annotations to correctly identified orthologs (Kunin et al., 2008).

What is metagenomic sequence?

What is Shotgun Metagenomic Sequencing? Shotgun metagenomic sequencing allows researchers to comprehensively sample all genes in all organisms present in a given complex sample. The method enables microbiologists to evaluate bacterial diversity and detect the abundance of microbes in various environments.

What is the purpose of metagenomics?

Metagenomics enables the study of all microorganisms, regardless of whether they can be cultured or not, through the analysis of genomic data obtained directly from an environmental sample, providing knowledge of the species present, and allowing the extraction of information regarding the functionality of microbial …

What are examples of metagenomics?

Metagenomics has been applied to explore pharmaceutical and industrial products from environmental samples. The most popular genes that have been isolated by metagenomics were polyketide synthases (PKS) genes, which are key enzymes for synthesizing polyketide antibiotics.

Why is metagenomic important?

What is whole metagenomic sequencing?

Whole Metagenome sequencing (WMS), or shotgun metagenome sequencing, is a relatively new and powerful sequencing approach that provides insight into community biodiversity and function.
