Bentonite and sepiolite as supporting media: Immobilization of catalase
TL;DR: In this article, a function of pH, temperature and ionic strength for free and immobilized enzyme activities on bentonite and sepiolite was studied, and the results showed that the storage stabilities of immobilized catalases were higher than free catalase.

A New and Rapid Method for the Determination of Glucose by Measurement of Rate of Oxygen Consumption
TL;DR: In this article, a new glucose oxidase method employing a polarographic oxygen sensor with a circuit modified to record the rate of oxygen consumption is presented, which provides a direct measure of the glucose level in the sample; results are obtainable within 20 sec. after sample (100 µl.) addition and within 3 min after a blood sample is withdrawn from a patient.

[9] The kinetics of immobilized enzyme systems
TL;DR: The kinetic behavior observed when an enzyme is included within a solid matrix that is in contact with a solution, containing the substrate and, also, with the situation, in which the enzyme is attached to the interior surface of a tube, through which substrate solution is flowing.

Deactivation of immobilized beef liver catalase by hydrogen peroxide.
TL;DR: A model has been developed which predicts the rate of decomposition of peroxide and inactivation of catalase in a flow reactor and first order dependence on peroxide concentration is assumed.
Journal ArticleDOI
An enzyme coimmobilized with a microorganism: The conversion of cellobiose to ethanol using β‐glucosidase and Saccharomyces cerevisiae in calcium alginate gels
TL;DR: The coimmobilized preparation was superior to a combination of separately immobilized biocatalysts, however, in this preparation, one‐half the enzyme activity was lost within a week when incubated at the operational temperature in the absence of substrate.
Journal ArticleDOI
High‐yield method for immobilization of enzymes
TL;DR: Two types of polyethylenimine‐coated glass microbeads were synthesized and used for the immobilization of glucose oxidase from Aspergillus niger and catalase and found to be superior to the immobilized activities attainable on aminopropyl‐activated glass microBeads.
