Metagenomics and Urban Microbiomes: Studying Cities as Ecosystems

 

Metagenomics is transforming the field of microbiology by enabling the direct analysis of genetic material from environmental samples without the need for traditional culturing techniques. This revolutionary approach has vast applications in human health, environmental science, biotechnology, agriculture, and antibiotic discovery, making it a key driver of scientific innovation.

With the growing demand for microbial research, disease diagnostics, and biotechnological advancements, the global metagenomics market is experiencing rapid growth. In 2022, the market was valued at US$ 1.6 billion, and it is expected to expand at a CAGR of 12.9% from 2023 to 2031. By the end of 2031, the industry is projected to reach US$ 4.6 billion, reflecting the increasing adoption of metagenomics across various sectors.

What is Metagenomics?

Metagenomics is the study of entire microbial communities by analyzing their collective DNA or RNA. This approach eliminates the need to cultivate individual microorganisms, making it possible to explore previously unknown and unculturable microbes. By using next-generation sequencing (NGS) and bioinformatics tools, metagenomics helps scientists understand microbial diversity, functional genes, and interactions within an ecosystem.

Key Drivers of Metagenomics Market Growth
