Pond scum ethanol
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.Research paper:
