Microbiome Sequencing Use Cases & Applications

Microbiome sequencing empowers scientific and clinical communities to dissect entire microbial communities through targeted (e.g., 16S rRNA gene) and untargeted (shotgun metagenomics) sequencing approaches. Over the last decade, advances in next generation sequencing (NGS) technologies, optimized DNA extraction, and robust bioinformatic analysis have transformed the study of microbial diversity, linking shifts in the human gut microbiome, environmental samples, and industrial fermentations to measurable impacts on health, sustainability, and product innovation.

This blog surveys the real-world microbiome sequencing use cases powering research, diagnostics, and commercial development for a diverse range of stakeholders.

Defining Microbiome Sequencing: Methods & Significance

Microbiome sequencing refers to the process of identifying and quantifying the microorganisms: bacteria, archaea, fungi, and eukaryotic microorganisms within a sample by analyzing their nucleic acids using next generation sequencing. The three most common methodologies are:

• 16S rRNA Gene Sequencing: Targets the highly conserved 16S ribosomal RNA gene in bacteria and archaea. Amplicon sequencing of hypervariable regions allows for taxonomic classification of bacterial species and genera within diverse samples. It is cost-effective for high-throughput detection but offers limited functional or strain-level resolution.
• Whole-Genome Shotgun Metagenomics: Sequences all genomic DNA (metagenomic DNA) from entire microbial communities. This approach enables taxonomic classification, functional gene analysis, and detection of horizontal gene transfer, antibiotic resistance genes, and non-bacterial taxa. It offers species- and sometimes strain-level characterisation of microbial communities.
• Targeted Gene Panels and ITS Sequencing: Targets distinct genes or genetic regions, such as ITS for fungi or 18S rRNA for eukaryotes. These panels broaden detection to non-bacterial microorganisms and offer solutions for environments dominated by fungi or protists.

The critical role of microbial community profiling includes:

• Enabling basic biomedical research on the human microbiome and chronic diseases.
• Supporting environmental monitoring by mapping microbial diversity in soil, water, and wastewater.
• Optimizing product development in the food, cosmetic, pharmaceutical, and industrial bioprocessing sectors by leveraging microbial genomics and monitoring microbial cells throughout the process.

A broad spectrum of industries: clinical laboratories, agriculture, aquaculture, pharma, consumer products, and environmental agencies use microbial sequencing to address regulatory, safety, efficacy, and sustainability challenges.
