1. A method of saccharifying a cellulosic or lignocellulosic material comprising: contacting
(i) a saccharifying agent that is immobilized on fibers or particles of a synthetic material, wherein the synthetic material is a synthetic fiber, a plastic fiber, or a synthetic polymeric material, with (ii) a cellulosic or lignocellulosic material to saccharify the cellulosic or lignocellulosic material,wherein the saccharifying agent is an enzyme or microorganism, wherein the synthetic material has been functionalized with carboxylic acid groups by irradiating the synthetic material with ionizing radiation, and wherein the immobilization is due to interaction between functional groups on the fibers or particles and functional groups on the saccharifying agent.
