Solving enteric fermentation with performance digestion.

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.

Methane (CH4)


Global green house emissions from ruminant methane.


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

The science of performance digestion.

Methane emissions are not only harmful to the environment, but they represent wasted nutrition in animal feed. Every molecule of methane belched into the atmosphere is energy that could otherwise have been utilised by the animal to produce meat, milk, or wool.

Our products are designed to consistently realise this productivity benefit through a process we call Performance Digestion.

Delivering change at a global scale.

Performance Digestion opens up exciting possibilities for innovation across various industries by harnessing the power of microorganisms to produce valuable and sustainable products at low cost and large scale.

At Number 8 Bio we're using Performance Digestion and 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.
