Basic catalase high-yield strain and basic catalase prepared by fermentation method using same

Abstract

A bacterium with high yield of alkaline hydrogen peroxidase and method for producing hydrogen peroxidase through fermenting the bacterium belongs to the field of bioengineering technique. The bacterium of the invention is Bacillus subtilis (CCTCC NO:M206062) screened from effluent water of textile mill workshop through air bubble generation conditions by dropping 5% H2O2 on the plate. Alkaline hydrogen peroxidase with 3200u / ml enzyme activity is obtained by fermenting the bacterium through shaking flasks for deep liquid fermentation. The alkaline hydrogen peroxidase can be used for treating texture dying.

Description

Technical field

[0001] A high-producing alkaline catalase bacteria and the fermentation method for producing alkaline catalase by using the strain, in particular a Bacillus strain with high alkaline catalase production, belong to the technical field of biological engineering. Background technique

[0002] The textile industry is a major industry in many developing countries, and it is also my country's traditional industry and pillar industry. The textile industry is an industry that produces very serious pollution. Especially in the printing and dyeing process, traditional processes consume a lot of water and chemicals, which not only consume resources, but also cause environmental pollution and disrupt ecological balance. This is essential to the implementation of sustainable development strategies. Extremely unfavorable. To fundamentally change the traditional extensive economic growth mode of high consumption and high pollution in the textile industry, we must vigorously prom...
