Can microorganisms be a solution to the world's energy problems?

Microorganisms once reigned supreme on the Earth, thriving by filling every nook and cranny of the environment billions of years before humans first arrived on the scene. Now, this ability of microorganisms to grow from an almost infinite variety of food sources may play a significant role in bailing out society from its current energy crisis, according to the Biodesign Institute's Bruce Rittmann, Rosa Krajmalnik-Brown, and Rolf Halden.
