Why does Wallaby not emit Methane?

When hoofed animals like buffaloes, cows, sheep, deer, etc. digest food they often produce methane gas, which is also the main greenhouse gas (warming the Earth). But the kangaroo called Wallaby does not produce this gas in their digestive tract.

The cause of the difference is due to the presence of a separate group of bacteria present in this species. Researchers have studied and isolated a species of intestinal bacteria called Wallaby group 1 (WG-1). When cultivating them in an appropriate nutrient environment, the bacteria produce succinate instead of methane as the final product.

Perhaps, many people feel ridiculous or ridiculous because why we are going to learn this. However, they are of great practical significance because succinate is not a greenhouse gas, so scientists hope that further research on WG-1 will help to understand how to convert cattle to produce less. More methane gas.
