Space efficient microbial strain of 22nd recoverable satellite, preparation and application thereof

Abstract

The invention relates to an excellent microorganism strain for space mutation, in particular to a good microorganism strain for space mutation, and the preparation method and the application thereof. The discoveries that the bump of a cancer patient infected by hemolytic streptococcus can subsidise naturally and the hemolytic streptococcus and the preparation thereof have a certain of biological activities are made is as early as in the 19th century. In the invention, the special environment of the outer space is utilized to deliver the strains to the outer space through carrying the 22nd recoverable experimental science satellite, the 22nd recoverable experimental science satellite safely returns after traveling for a certain period of time, the suppresormutation strains are eliminated, the forward mutation strains with excellent features are selected out for re-screening, and ultimately the excellent microorganism strains with vigorous life, quick growth speed, high fermentation yield, short fermentation period, high polypeptide content, stable hereditary property, strong productive adaptability and space cumulative effect. The microorganism strain can be applied to the strains for industrialization production, and has the advantages of high output, wide application range, low cost and high effective component content.

Description

technical field [0001] The invention relates to an excellent microbial strain for space mutagenesis, in particular to an excellent microbial strain for space mutagenesis and its preparation method and application. Background technique [0002] Microorganisms are a class of tiny organisms that are closely related to human beings, with diverse types and complex functions. Some microorganisms play a very important role in the research and development of drugs. The main links in the research and development of microbial drugs include the selection of strains, optimization of fermentation processes, research on extraction and refining processes, etc. [0003] As early as the nineteenth century, it was discovered that the tumors of cancer patients infected by hemolytic streptococcus naturally subsided, and people successively found that hemolytic streptococcus and its preparations had certain pharmacological activities. [0004] The vast space is boundless, with unimaginable envi...
