267. Survivor's Yeast

Survivor's yeast (actually an entire ecosystem of microorganisms) can metabolize any mixture of organic material and water into an edible, if unpalatable slurry. On Earth, almost all types of dirt could be rendered into food, and so the stuff, stored as freeze-dried packets of powder, could be found in emergency kits, soldiers packs and survivalist bunkers. There is little that the yeast can metabolize in the rest of the solar system, but it is still sometimes used by the poor and desperate to eat a maker's feedstock without a maker.
