In order to produce a bioethanol at low cost from cellulosic biomasses, it is effective to increase the reduction and recovery of the enzymes. However, saccharifying enzymes such as cellulases, not only adding the enzyme does not act effectively for adsorption to lignin, the recovery rate of the enzyme is also lowered. Therefore, in order to suppress the adsorption to lignin, novel synthesized blocking agent in enzyme reaction solution was investigated. As a result, when 17 types of polymers were investigated, the copolymer of 2-methacryloyloxyethyl phosphoryl choline (BE A-NA) could be 83.5% prevent adsorption to lignin.
