Microbiome Analysis

Microbiome analysis involves the study of the vast communities of microorganisms, including bacteria, archaea, fungi, and viruses, that inhabit a particular environment. By employing high-throughput DNA sequencing techniques, such as 16S rRNA gene sequencing and shotgun metagenomics, coupled with powerful bioinformatic tools, researchers can determine the composition (who is there) and functional potential (what they can do) of these complex microbial ecosystems. This field is critical for understanding the intricate relationships between microbiomes and their hosts or environments, providing crucial insights into areas ranging from human health and disease to global nutrient cycling.
