Pond scum ethanol

  April 28/May 5, 2008
A blue-green algae that's genetically modified to include genes from a cellulose-producing bacteria promises to turn pond scum into an efficient, inexpensive source of feedstock for producing ethanol. The algae lives on sunlight, and the cellulose it produces is more easily converted to ethanol than the cellulose from plant matter.
