Elucidation of native California Agave americana and Agave deserti biofuel potential: Compositional analysis.

Because biofuels have the unique potential to be rapidly deployed in existing transportation fuel infrastructures, they should play a major role in helping California quickly meet its aggressive goals to substantially reduce greenhouse gas contributions by this major sector. Furthermore, energy crop...
