摘要
用碱一氧一蒽醌蒸煮麦草所得纤维素为原料，研究了纤维素酶解的影响因素．结果表明：预处理后的麦草纤维素，其木质素含量较低，而酶解率和木质素脱除率均较高，在４５～５０℃、 ｐＨ为 ４．４、底物与酶量之比为１：０．０２、反应时间为 ３０ ｈ、转速为 １００ ｒ／ｍｉｎ时，可获得较理想的酶解率和木质素脱除率，二者分别可达７４．５％和１９．２％
The enzymolysis of cellulose from alkali-Oxygen-anthraquinone cooking wheat straw by cellulase was studied. The results showed that the rate of enzymolysis and delignifi- cation reaChes up to 74.5% and 19.2% respectively under the conditions of pH 4.4, 45-50℃, ratio of substrate to cellulase amount 1：0.02 and reaction time of 30 h.
