Super-scum. Again.

This is more covering-the-coverage than flogging a new discovery, but the New York Times is keeping tabs on the process of turning pond scum into an industrial fuel source:

Foreign genes are being spliced into algae and native genes are being tweaked.

Different strains of algae are pitted against one another in survival-of-the-fittest contests in an effort to accelerate the evolution of fast-growing, hardy strains.

The goal is nothing less than to create superalgae, highly efficient at converting sunlight and carbon dioxide into lipids and oils that can be sent to a refinery and made into diesel or jet fuel.

Dozens of companies, as well as many academic laboratories, are pursuing the same goal — to produce algae as a source of, literally, green energy. And many of them are using genetic engineering or other biological techniques, like chemically induced mutations, to improve how algae functions.

“There are probably well over 100 academic efforts to use genetic engineering to optimize biofuel production from algae,” said Matthew C. Posewitz, an assistant professor of chemistry at the Colorado School of Mines, who has written a review of the field. “There’s just intense interest globally.”
