Microbes for Biofuels

This Scientificblogging news story recounts the work of Arizona State University researchers' efforts to engineer cyanobacteria to excrete fatty acids through their cell walls — a key step to developing the microbes as a source of biofuel. First, the researchers inserted thioesterase to remove the fatty acids from their carriers and then they altered S and peptidoglycan layers of the cell wall to better allow secretion.
