Application

来自 曲霉 的纤维素酶。在 BBC（生物可吸收细菌纤维素）生物降解性分析期间，已用于将纤维寡糖降解为葡萄糖。这种酶还被用于光子相关光谱，以研究其对未过滤啤酒样品的影响。该光谱分析中评价的参数为悬浮颗粒的大小、流速和混浊稳定性。

Biochem/physiol Actions

纤维素酶是水解纤维素的酶，是由 β-1,4-糖苷键，与葡萄糖连接。内切-β-葡聚糖酶是纤维素酶复合体的主要组成酶之一。通过随机裂解分子内的糖残基来催化纤维素水解。外切-β-D-葡聚糖酶和 β-葡萄糖苷酶可协同作用将纤维素转化为葡萄糖，因此可用于工业规模。

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What is the density of Product C2605, Cellulase from Aspergillus sp.?

    The density of this cellulase solution is approximately 1.2 g/mL.

  4. How are the activity units of Product C2605, Cellulase from Aspergillus sp., listed on the C of A?

    The activity of cellulase given on the C of A is in units per gram of liquid.

  5. What are the supplier's working conditions for determining the activity for Product C2605, Cellulase from Aspergillus sp.?

    This product is assayed using carboxymethycellulose as substrate, at 40°C, at a pH of 7.5.

  6. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  7. What is the unit activity of the Cellulase from Aspergillus sp. enzyme, Product C2605?

    We provide the unit activity of the product in terms of units/g, for each individual lot. To get a units/mL value, one can use the density value of approximately 1.2 g/mL to convert to a units/mL value for each lot.

  8. What is the optimum pH for Cellulase from Aspergillus sp., Product C2605?

    At a temperature of 40°C, Novozyme has found ~pH 8.0-8.2 to be the optimum pH range for this enzyme.
