Cellulose was treated with different extracellular microbial enzymes. The treatment of cellulose with the enzymes can improve alkaline solubility. Both endoglucanase and crude cellulase decreased the average degrees of polymerization ([see text]) and improved the alkaline solubility of cellulose most efficiently. The composition of the enzyme, the type of cellulosic materials, pretreatment, and the treatment conditions are the key factors for its effective processing, using the enzymes to improve on alkaline solubility of cellulose. The improvement in the alkaline solubility is caused by the decrease in [see text] and hydrogen bond because of enzymatic hydrolysis.
纤维素用不同的细胞外微生物酶进行处理。用这些酶处理纤维素可提高其碱溶性。内切葡聚糖酶和粗纤维素酶都降低了平均聚合度([见原文]),并最有效地提高了纤维素的碱溶性。酶的组成、纤维素材料的类型、预处理以及处理条件是利用这些酶有效提高纤维素碱溶性的关键因素。碱溶性的提高是由于酶促水解导致[见原文]和氢键减少所致。
