Shitake Mushrooms make Gourmet Biofuel

We often make fun of ethanol as a less-than-zero sum game, but people keep trying. In the forest, Shitake mushrooms produce an enzyme that dissolves wood, turning it into sugars that they feed on and creating rich soil. In the lab, scientists at the US Department of Agriculture have isolated the gene that creates the enzyme, and GM'ed a yeast to produce it. They hope that it can be used to digest rice hulks and harvest leftovers to make lots of ethanol. And, it may make an interesting risotto.::Renewable Energy Access
