Abstract:
1. A method for making acids, the method comprising: contacting a pretreated biomass feedstock with a microorganism or an enzyme to saccharify the pretreated biomass material and release sugars, and fermenting the sugars to a poly-functional organic acid, wherein the feedstock has been pretreated by irradiating with an electron beam at a dose rate of at least 1.0 Mrad/s for a time sufficient to deliver from about 10 Mrad to about 150 Mrad of radiation to the biomass feedstock, and wherein the biomass feedstock comprises a cellulosic or lignocellulosic material.
