University of Guelph researcher Emma Allen-Vercoe and her team have devised a method for creating artificial poop for use in fecal transplants, a promising therapy for people whose intestinal flora have been damaged by illness, antibiotics, or other therapies. The recipe involves a combination of indigestible cellulose and a starter culture of fecal bacteria. These are mixed in an airtight chamber and passed through a "robogut" — a mechanical analog of the human digestive system that produces the finished turd.
Emma Allen-Vercoe: It contains things like the indigestible cellulose that's left after a meal has passed through your digestive tract and down to your distal gut, the end of the line for digestion. It's pretty nasty-looking. It's a brown sludge, it's got lumps of starch, and it's kind of gloopy. It doesn't look or smell very appetizing.
PS: How do you turn that sludge into a fecal transplant?
EAV: Robogut. Robogut is made of six big beakers full of that sludge that are warmed to body temperature. And we add the bacteria from a small amount of human feces. Since oxygen is poison to anaerobic gut bacteria, each vessel is sealed to make it airtight, while sensors monitor temperature and acidity.
