Abstract

Methods for mixing a pretreated cellulosic biomass feedstock using a centrifugal mixer prior to reactions in a bioreactor.

Claims

13-1. The method according to claim 1, wherein the rotor comprises vanes or blades to propel the pretreated the pretreated cellulosic biomass feedstock from a center of the centrifugal mixer to an outer edge of the centrifugal mixer.
