The term metagenomics has been defined as “The study of DNA from uncultured organisms”  (Jo Handelsman). A genome is the entire genetic information of one organism, whereas a metagenome is the entire genetic information of an ensemble of organisms. It is a culture-independent tool for studying bacterial, viral, fungal or eukaryotic communities and can be divided in two main categories.

  1. One is to focus on specific marker genes for taxonomic identification only. For this so-called targeted amplicon approach, the ribosomal small subunit RNA (16S / 18S rRNA) gene has emerged as the most used marker.
  2. Alternatively, the use of the entire DNA or RNA for sequencing is often referred to as whole genome shotgun (WGS) metagenomics offering a random representation of all extracted genomic sequences, giving deep insights into the

    taxonomic and metabolic profiles of these communities. In addition to the information about taxonomic diversity (who is there), shotgun metagenomics gives insight into the physiology of the organisms present in the environment (what are they doing). It has been estimated that >99% of the microbial numbers in nature are non-culturable by available techniques. Hence, new cultivation-independent methods to study the function and diversity of microorganisms in nature are needed. As the price of DNA sequencing continues to fall, metagenomics now allows microbial ecology to be investigated at a much greater scale and detail than before.
