10585826 story Frog Foam Photosynthesis 21 Posted by samzenpus on Thursday March 18, 2010 @12:00PM from the how-green-are-your-frogs dept. Garrett Fox writes "University of Cincinnati researchers describe a method of getting photosynthesis from a high-surface-area foam containing enzymes that produce sugar using light and CO2 (abstract). Oddly, the foam itself is derived from a species of frog. More interesting is that the technique doesn't use whole cells or apparently even chloroplasts. The researchers claim 'chemical conversion efficiencies approaching 96%,' as well as tolerance for deliberately high-CO2 environments."
