World Kimchi Research Institute discovers virus-resistant lactic acid bacteria in Mugunji kimchi = South Korea

The World Kimchi Research Institute announced on the 10th that it has discovered lactic acid bacteria that are highly resistant to viruses in mugunji kimchi that has been aged at low temperatures, and confirmed its mechanism of action to prevent genes from entering from outside, such as viruses.
did. The institute collected 34 pieces of mugunji kimchi from all over Korea that had been fermented at low temperatures for over six months and analyzed the microbiological characteristics contained within. In more than 88% of the collected samples, lactic acid bacteria
Pediococcus inopinatus was found to be the dominant bacterial species. The institute also found through genetic analysis that Pediococcus inopinatus is a very well-developed Chris.
It has also been confirmed that it has a CRISPR system. CRISPR is a unique base sequence found in bacteria. The genetic information of viruses that have invaded in the past is converted into a specific part of your own genes.
It becomes a defense system that destroys a similar virus if it subsequently invades. Recently, in the kimchi industry, kimchi production using lactic acid bacteria has been introduced to control the quality of kimchi.
It is carried out. In the future, when lactic acid bacteria are used as fermentation starter bacteria, the results of this study can be used to improve immunity against viruses.
``The crisper system of Pediococcus inopinatus is diverse.
"They have an immune spectrum that can deal with many types of viruses, and we will examine their immune function against viruses from multiple angles through future research."
