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. Shotgun metagenomics also provides a means to study unculturable microorganisms that are otherwise difficult or impossible to analyze.
Unlike capillary sequencing or PCR-based approaches, next-generation sequencing (NGS) allows researchers to sequence thousands of organisms in parallel. With the ability to combine many samples in a single sequencing run and obtain high sequence coverage per sample, NGS-based metagenomic sequencing can detect very low abundance members of the microbial community that may be missed or are too expensive to identify using other methods.
16S rRNA Sequencing is another method used for metagenomics studies.
There are multiple ways to perform shotgun-based metagenomic sequencing experiments, but these are some suggested products for each step of the workflow.
