Solving enteric fermentation with precision fermentation.

What is enteric fermentation?

Enteric fermentation refers to the digestive process that occurs in the stomachs of ruminant animals such as cows, sheep, and goats. These animals have a unique digestive system that allows them to break down and extract nutrients from plant material, particularly cellulose, which is otherwise indigestible to most other animals.

During the enteric fermentation process, microorganisms in the animal's stomach produce methane gas as a byproduct, which is then expelled by the ruminant, mainly through belching.

Global green house emissions from ruminant methane.


Methane is 28x worse for trapping heat than carbon dioxide.

Synthetic Biology & the science of precision fermentation.

Synthetic biology is a field of science that involves the design and engineering of biological systems to create new functions or modify existing ones. It combines principles from biology, engineering, and computer science to customise, improve, and scale natural systems.

Precision fermentation, is a technique we use that focuses on using microorganisms, such as bacteria or yeast, to produce specific compounds or substances through fermentation. Instead of using fermentation to produce beer or wine, the micoorganisms are fine-tuned to make defined products in a controlled and precise manner.

Leveraging synthetic biology to deliver change at a global scale.

Synthetic biology and precision fermentation open up exciting possibilities for innovation across various industries by harnessing the power of microorganisms to produce valuable and sustainable products at scale.

At Number 8 bio, we are using synthetic biology to lead the path to a green agricultural revolution.

Artist interpretation of pollution

From pollution to solution.

Through synthetic biology we are using microorganisms capable of growing on greenhouse gases to make food. Greenhouse gases are fed to trillions of carbon-hungry microbes that turn pollution into valuable animal feeds.

This can reduce arable land use, cutting down on agricultural emissions significantly. Our solution is scalable and effective.

Good people, doing good work with real impact.
