Enteric fermentation

Enteric fermentation is a digestive process by which carbohydrates are broken down by microorganisms into simple molecules for absorption into the bloodstream of an animal.

The IPCC reports that methane is more than twenty times as effective as CO2 at trapping heat in the atmosphere - though note that it is produced in substantially smaller amounts.

This is because the gut microbiota of Macropodids, rumen and others parts of their digestive system, is dominated by bacteria of the family Succinivibrionaceae.

[10] Another approach to manage methane emissions from enteric fermentation involves using diet additives and supplements in cattle feed.

[11] For example, Asparagopsis taxiformis (also known as red seaweed) is a species of algae that when fed to cattle has shown to substantially reduce their methane emissions.
