High yield fungus for alkali pectinase and screen method as well as ferentation method for producing alkali pectinase by using the strain

Abstract

A Bacillus pumilus (CCTCC No.M203042) for preparing the alkaline pectinase wigh high ouput is disclosed. It is obtained by the plate transparent ring screening of putrescent tangerine peel. Said alkaline pectinase used for refining cotton fabrics is prepared through deep fertilization with said Bacillus pumilus.

Description

technical field [0001] The invention relates to a high-yielding alkaline pectinase bacterium, a screening method thereof, and a fermentation method for producing alkaline pectinase by using the strain, belonging to the technical field of bioengineering, in particular to a bacillus strain with high production of alkaline pectinase. Background technique [0002] Due to the natural impurities in cotton fiber, the traditional cotton textile dyeing and finishing process needs to consume a lot of water and chemical substances, which not only consumes resources, but also seriously pollutes the environment, which is no longer suitable for the development of the whole society. The way to solve this problem is to develop an environment-friendly dyeing and finishing process, that is, a green dyeing and finishing process, and the application of biotechnology is one of the important ways. [0003] In the process of cotton textile processing, the application of biotechnology is becoming m...

Problems solved by technology

Although a series of enzymes developed by foreign companies have been reported to have a good application in foreign countries, due to the large differences in the quality of cotton in various production areas, the effect in our domestic cotton textile processing and use is not satisfactory, and it has not been very successful. good promotion

At the same time, there are no domestic research reports on the application of self-developed alkaline pectinase and the screening of its producing bacteria.
