To provide an enzyme composition having reduced adsorptivity on cellulose-containing biomass.SOLUTION: An enzyme composition contains unused cellulase having the enzymatic activity of decomposing p-nitrophenyl-β-lactopyranoside, lignin and water. The cellulase and the lignin dissolve in water. The ratio of the lignin mass to protein mass in an aqueous solution, measured by the Bradford assay, is 1 or more.SELECTED DRAWING: None 【課題】本発明は、セルロース含有バイオマスに対する吸着性が低減した酵素組成物を提供する。【解決手段】ｐ－ニトロフェニル－β－ラクトピラノシドを分解する酵素活性を有する未使用のセルラーゼ、リグニンおよび水を含有する酵素組成物であって、前記セルラーゼおよび前記リグニンは水に溶解し、ブラッドフォード法で測定される水溶液中のタンパク質の質量に対する前記リグニンの質量比率が１以上である、酵素組成物。【選択図】なし
