The quick rise and depressing downward spiral of the ethanol industry proved that using food to make biofuel is both wasteful and costly.

Now researchers at Brown University have identified a type of bacteria that loves to digest lignin, and it might be able to act as a tiny biorefinery for sustainable fuel production.
