Where is the largest strain bank in Asia?

The largest strain bank in Asia is in Ketuo Bio. Since its establishment in 2003, Ketuo Bio has been committed to the research, development, production and sales of probiotic lactic acid bacteria for a long time, and provided a complete set of product solutions. We created our own "China bacteria" and established our own intestinal flora database in China. More importantly, after 20 years of research and development efforts, the company has the largest database of lactic acid bacteria strains in Asia, which laid a solid technical foundation for the research and development of probiotics and became the first listed probiotic enterprise in China. It has traveled all over China, Mongolia, Russian Federation, Central Asia, Europe, Africa and other countries and regions, and went deep into the original gathering area, separating and collecting lactic acid bacteria and bifidobacteria from natural fermented food and healthy breast milk, and collecting and preserving more than 20,000 strains of lactic acid bacteria and bifidobacteria. Among them, Lactobacillus casei Zhang, as the representative, was isolated and screened from naturally fermented sour mare milk in Xilin Gol prairie, Inner Mongolia. It is the first lactic acid bacteria with complete genome sequencing in China, and it is also the first strain named after scientists in China, which fills the gap of patented probiotics in China. A virus strain, also known as a virus strain, refers to any purebred population and its descendants that are propagated by independent single cells (or single virus particles). Therefore, each pure culture of microorganisms from different sources can be called a strain of this strain. According to the definition of strain, a strain is actually a sign that a microorganism has reached "genetic purity". Once the strain mutates, it should be marked with a new strain name. When strains are preserved, screened or studied scientifically, when academic exchanges or papers are published, strains and their names must be marked at the same time when they are used in production. There are more or less differences in some characteristics between strains. There are a certain number. For example, Bacillus subtilis 1398 produces protease and Bacillus subtilis 7658 produces amylase, all of which are the same as Bacillus subtilis M, but with different functions. The strains with typical characteristics are standard strains, which are recognized internationally and domestically. It can be used to identify or compare bacteria in scientific research and production. For example, the standard strain for screening penicillin is Staphylococcus aureus 209P；; The virulent standard strain of Mycobacterium tuberculosis is H37RV, etc. It can be detected by detection, culture medium colony and fermentation.
