ScienceDaily: An Arizona State University research team has developed a process that removes a key obstacle to producing lower-cost, renewable biofuels. The team has programmed a photosynthetic microbe to self-destruct, making the recovery of high-energy fats–and their biofuel byproducts–easier and potentially less costly. "The real costs involved in any biofuel production are harvesting the goodies and turning them into fuel," said Roy Curtiss, director of the Biodesign Institute’s Center for …
