Abstract :
[en] Metagenomics has proven to be a powerful tool in exploring a large diversity of natural environments such as air, soil, water, and plants, as well as various human microbiota (e.g. digestive tract, lungs, skin). DNA sequencing techniques are becoming increasingly popular and less and less expensive. Given that high-throughput DNA sequencing approaches have only recently started to be used to decipher food microbial ecosystems, there is a significant growth potential for such technologies in the field of food microbiology. The aim of this review is to present a survey of recent food investigations via metagenomics and to illustrate how this approach can be a valuable tool in the better characterization of foods and their transformation, storage and safety. Traditional food in particular has been thoroughly explored by global approaches in order to provide information on multi-species and multi-organism communities.
