General description
Wir sind darauf bedacht, Ihnen umweltfreundlichere Alternativprodukte anzubieten, die mit einem oder mehreren der „12 Grundsätze der Grünen Chemie“ in Einklang stehen. Dieses Produkt wurde für den Einsatz in der Celluloseethanol-Forschung im Hinblick auf Energieeffizienz und Abfallvermeidung verbessert. Weitere Informationen finden Sie im Biofiles-Artikel und unter Enzyme für die alternative Energien-Forschung
Application
Cellulase aus Aspergillus sp. wurde bei der Analyse der biologischen Abbaubarkeit von BBC (bioabsorbierbarer Bakteriencellulose) zum Abbau von Cello-Oligosacchariden zu Glucose verwendet. Das Enzym wurde auch in der Photonenkorrelationsspektroskopie zur Untersuchung seiner Wirkung auf unfiltrierte Bierproben eingesetzt. Die bewerteten Parameter dieser spektroskopischen Analyse waren die Größe der suspendierten Teilchen, der Durchfluss und die Trübungsstabilität.
Biochem/physiol Actions
Cellulasen sind Enzyme, die Cellulose, ein lineares Polymer aus Anhydroglucoseeinheiten, die durch β-1,4-Glykosidbindungen verbunden sind, zu Glucose hydrolysieren. Endo-β-D-glucanase ist eines der Hauptkomponentenenzyme des Cellulasekomplexes. Es katalysiert die Hydrolyse von Cellulose durch zufällige Teilung der Zuckerreste innerhalb des Moleküls. Exo-β-D-glucanase und β-Glucosidase können Cellulose synergistisch zu Glucose umwandeln, und werden daher im industriellen Maßstab eingesetzt.
Preparation Note
Hergestellt durch Submersfermentation eines genetisch verändertem Aspergillus-Mikroorganismus

What is the total protein content (% w/w or mg/mL) of the liquid formulation?
1 answer-
This is a product of Novozyme Corp. The protein content is not among its release specifications. Its efficacy is determined by its enzymatic activity in terms of units per gram liquid. 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.
