Optimization of enzymatic pretreatment and saccharification processes of sawdust for bioethanol production

A widespread interest has been devoted to the production of ethanol from sustainable renewable materials to compensate for the impending fossil fuel crisis. Lignocellulosic biomasses, such as sawdust and others, are an attractive, abundant, cheap and non-food competitive biomass feedstock for cheape...
