Problems solved by technology

For a long time, my country has adopted natural selection and physical and chemical factors for microbial breeding, and the breeding methods obtained are far from meeting the needs of the pharmaceutical industry. At present, compared with similar high-yielding strains in the world, there is a big gap in their production potency
The production cycle and fermentation cycle of the strain are long, the output for industrial production is low, the price is expensive, the scope of use is small, and the content of active ingredients is low

[0077] Preparation and loading of space-borne strains

[0078] The researchers of this project used methods such as filter paper strips, immersion medium, and sand tubes to encapsulate α-hemolytic streptococci. The bacteria were packed into a packaging bag code-named DZ25, and the packaging bag was pasted with a seal from the Beijing Notary Office , and stamped with the evidence preservation seal. On August 29, 2005, the above bacteria were sealed and loaded into the return capsule of the 22nd returnable science and technology experiment satellite. The China Jiuquan Satellite Launch Center was launched by the Long March 2D carrier rocket. After 18 days of orbital operation, the return module of the 22nd returnable science and technology test satellite was launched at 11:20 on September 16, 2005. It was recovered and landed in central Sichuan at 18:00, and the return capsule was transported to the China Academy of Space Te...

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...
