What reaction does Glucose Oxidase CAS 9001-37-0 catalyze?

Glucose oxidase catalyzes the oxidation of beta-D-glucose to D-glucono-delta-lactone and hydrogen peroxide while consuming oxygen. The lactone then hydrolyzes further to gluconic acid in aqueous systems.

What does the enzyme activity specification such as 10,000-150,000 U/g mean?

Activity is measured in enzyme units per gram of powder, so a higher U/g value means less enzyme is needed to oxidize a given amount of glucose. The product can be customized across that range to match industrial, food, diagnostic, or research requirements.

What are the optimum pH and temperature for Glucose Oxidase?

Typical glucose oxidase preparations work best around pH 4.5-6.5 and 30-50 degrees C, depending on the source and formulation. High temperatures reduce enzyme stability, so the process should stay within the selected product's thermal range.

How is GOD enzyme used as an oxygen scavenger in food and fermentation?

By oxidizing glucose, the enzyme consumes dissolved oxygen and produces hydrogen peroxide, helping limit oxidation and the growth of aerobic microorganisms. This oxygen-depletion function is useful in food preservation and in fermentation processes that need reduced oxygen levels.

Why is Glucose Oxidase used in glucose biosensors and diagnostic assays?

It is a core recognition element because its reaction rate changes with glucose concentration and can be coupled to oxygen electrodes or colorimetric peroxide detection. This allows precise glucose quantification in biosensor strips, clinical analyzers, and biochemical test kits.

Glucose Oxidase (GOD) Enzyme CAS 9001-37-0

Glucose Oxidase (CAS 9001-37-0), also known professionally as GOD enzyme or fungal glucose oxidase, is a high-purity oxidoreductase derived through submerged fermentation of Aspergillus niger. This potent biocatalyst is indispensable in the textile industry for controlled peroxide removal and in food processing as an efficient oxygen scavenger to extend shelf life. Our enzyme preparation is engineered for high catalytic efficiency, ensuring the rapid conversion of beta-D-glucose into gluconic acid and hydrogen peroxide under mild industrial conditions. we provide bulk supply for global distribution, offering customized specifications ranging from 10,000 U/g to over 150,000 U/g.

Applications

Textile Industry: Used as a biocatalyst in the bio-bleaching process to remove residual hydrogen peroxide and protect fiber integrity.
Industrial Fermentation: Applied as an oxygen scavenger to prevent oxidation and maintain anaerobic conditions in specific chemical synthesis environments.
Diagnostic & Research: Utilized in the formulation of glucose biosensors and biochemical assays for precise glucose quantification.
Food Processing: Acts as a preservative and stabilizer by inhibiting the growth of aerobic bacteria through oxygen depletion.

Storage & Safety

Glucose Oxidase should be stored in a cool, dry environment (ideally below 25°C) and kept away from direct sunlight and moisture to maintain enzymatic activity. As this is a biological enzyme, personnel should use Personal Protective Equipment (PPE), including dust masks and gloves, to avoid inhalation of powder or prolonged skin contact, which may cause sensitization in some individuals.

Quality Assurance

Our production facility utilizes advanced fermentation and purification technologies to ensure high catalytic efficiency. Quality control is maintained through rigorous Activity Assays (U/g) and microbial testing. Each batch is screened for heavy metal contaminants and enzymatic purity according to international industrial standards, ensuring consistent performance in diverse formulation environments.
