Inside a cow's stomach

Some researchers may have found a new way to make biofuel and it comes from a cow’s rumen. A cow’s first stomach that’s main use is for plant digestion. The way they’re doing this is by putting mesh bags of switchgrass in a cow’s stomach though a cannula. A cannula is a porthole like thing that lets someone look in side an animal’s stomach. The researchers believe that some of a cow’s stomach enzymes may help make less expensive bio-fuels.
