ABSTRACT:
An apparatus is disclosed for treating lignocellulosic materials, comprising an enzymatic conversion zone adapted to enzymatically convert alcohol to aldehyde and hydrogen peroxide, a delignification zone, a device for transferring an effluent comprising aqueous hydrogen peroxide from the conversion zone to the delignification zone, a chopper for adding chopped lignocellulosic material to the delignification zone, a separator for separating solid delignified material in the delignification zone from a liquid, and a fermenter adapted to grow alcohol oxidase-producing yeast, and means for transferring alcohol oxidase from the fermenter into the conversion zone.
