Bioethanol production from cogongrass (Imperata cylindrical)
Imperata cylindrical or cogongrass is one of the abundant low-value by-products of agriculture waste in the world. The research had provided a discussion of how this non-valuable agriculture waste can be managed to become an alternative bioresource for bioethanol production. For effective bioethanol...
