In environmental metagenomics, the community of organisms is sampled from a natural environment. PubMedGoogle Scholar, Handelsman, J. Metagenomics or Megagenomics?. Metagenomics refers to the study of genetic materials recovered from different environmental samples such as water, human faces, etc (Acharya et al., 2020). In its approaches and methods, metagenomics circumvents the unculturability and genomic diversity of most microbes, the biggest roadblocks to advances in clinical and environmental microbiology. They could sequence the DNA from the environment again using directed sequencing, probing for this target gene, and then identifying other genes on the same large fragment of DNA to identify the origin of that gene. To obtain Metagenomics is the study of the genomes in a micro- bial community and constitutes the first step to studying the microbiome. 2022 Jul 28. doi: 10.1038/s41579-022-00754-5.
