應用

Sigma 公司的纤维素酶已用于将纤维寡糖降解为葡萄糖;研究生物可吸收细菌纤维素 (BBC) 材料的生物降解性。
来自里氏木霉的纤维素酶已被用于研究,以评估纤维素酶转录因子 XYR1、ACE2 和 ACE 的差异调节。木霉 (Trichoderma reesei) 产纤维素酶也被用于研究水热预处理麦秸在高固含量下的液化。

生化/生理作用

纤维素酶是将纤维素水解成葡萄糖的酶。纤维素酶用于研究洗涤剂、制药、烘焙和酶制剂生产行业中职业性哮喘的发展。在洗涤剂中加入纤维素酶以改善清洁属性。也可应用于纸制品的生物降解,如纸浆纸、过滤器纸、报纸、办公用纸、微晶纤维素等。

單位定義

一个单位将在 pH 5.0 的 37℃ 下在 1 小时内从纤维素中释放出 1.0μmole 的葡萄糖(孵育时间为2小时)。

準備報告

存在浓度为 5 mg/mL 的 0.15% 聚六亚甲基双胍 (PHMB) 时,溶于无菌去离子 (DI) 水中。

Enzymatic liquefaction was studied by measuring continuously the flowability change of high-solids lignocellulose substrates using a real time viscometric method. Hydrolysis experiments of hydrothermally pretreated wheat straw were carried out with purified enzymes from Trichoderma reesei; Cel7A, Cel6A, Cel7B, Cel5A

Bioresource technology, 86(1), 21-23 (2002-11-08)
Environmental issues such as the depletion of non-renewable energy resources and pollution are topical. The extent of solid waste production is of global concern and development of its bioenergy potential can combine issues such as pollution control and bioproduct development
Thomas Portnoy et al.
Eukaryotic cell, 10(2), 262-271 (2010-12-21)
Due to its capacity to produce large amounts of cellulases, Trichoderma reesei is increasingly being investigated for second-generation biofuel production from lignocellulosic biomass. The induction mechanisms of T. reesei cellulases have been described recently, but the regulation of the genes

Microscopy research and technique, 79(9), 838-844 (2016-07-01)
Rice false smut, caused by the fungal pathogen Villosiclava virens, is one of the most important rice diseases in the world. Previous studies reported that the pathogen has less number of cell wall-degraded genes and attacks dominantly rice stamen filaments
Evgenij Lyagin et al.
Biotechnology journal, 5(8), 813-821 (2010-07-30)
The screening of catalysts, substrates or conditions in the early stages of bioprocess development requires an enormous number of experiments and is a tedious, expensive and time-consuming task. Currently available screening systems can only be operated in batch or fed-batch
