描述

Longzyme® Catalase CAS 9001-05-2

Hydrogen peroxide enzyme uses hydrogen peroxide as a specific substrate, and catalyzes the transfer of a pair of electrons, and eventually degrades it to water and oxygen. Product Characteristics
1, temperature range: effective temperature range 20-60 ℃ ℃, the optimal temperature range 40-55 ℃.
2, pH range: effective pH range 5.0-9.5, optimal pH range 6.0-8.0.
3、Effects of metal ions on enzyme activity: Hg’NY, CU, Fe have inhibitory effect on catalase; low concentration of A1, Zn, Mg, Ca have no effect on enzyme activity.

产品特性

1、Product specification: liquid type 50000, 200000u/mL. Liquid enzyme pH(25℃℃):6.0-7.0, capacity:≤1.25g/mL.
2, enzyme activity definition: in PH7.0, 30 ℃ conditions, 1min decomposition of 1umol hydrogen peroxide enzyme required for the definition of a unit of activity, expressed in u / mL.

应用方法

1, in the textile industry, the enzyme can remove the residual hydrogen peroxide after bleaching to shorten the process, energy saving, water saving, reduce the pollution of the environment. Recommended dosage 0.3-5mL/L (enzyme activity of 50000u/mL, the same below), suitable reaction conditions for 10-30min.
2, food and fresh milk preservation industry, the enzyme is used to remove residual hydrogen peroxide, the recommended dosage of 50-150mL/t fresh raw materials, 30-45 ℃ heat preservation 10-30min, do not adjust the pH.
3、Beer storage and sodium gluconate industry, the enzyme must be used in conjunction with glucose oxidase for the purpose of removing oxygen in beer and converting glucose into gluconic acid. In beer industry, the dosage of the enzyme is 20-100mL/t beer, stored at room temperature. In the sodium gluconate industry, the enzyme dosage of 2000-6000mL/t dry matter, concentration 30-35%, PH adjustment of 5.5 or so, 30-55 ° C transformation of about 30 hours.
4, pulp and paper industry, the enzyme is used to remove the residual hydrogen peroxide after bleaching pulp. Recommended dosage 100-300mL/t absolute dry pulp, 40-60 ° C treatment for about 30min, without adjusting pH.

包装和储存

Packed in plastic drum, 25kg/drum. This product is a biologically active substance, high temperature, strong acid, strong alkali will cause enzyme inactivation, so in the process of transportation and storage, sunlight exposure should be avoided. The warehouse should be kept clean, cool and dry.
