How cool is this? Here's a microbe that eats pee and craps rocket fuel. Hydrazine, to be specific.
Makes you want to run right out to the Mad Scientists Supply store, buy a bunch of petri dishes, and get right to work re-arranging them genetically to produce something the size of a cow with this kind of talent. You thought regular cow farts were bad? Trust me, you don't want to be anywhere near these babies.
If nothing else, it seems like the basis for a good B movie.
