Tridge summary

The National Institute of Fisheries Science has discovered a new microorganism, 'Massilia sp. NB-5', that produces violacein, a substance with antibacterial properties effective against the scutica worm and other fish diseases. The genome of this strain has been deciphered, and it was found that when cultured for 48 hours at 25° C, it can produce over 85 mg of violacein per liter. The institute has registered a patent for the new strain and plans to transfer the technology to related companies, with expectations for its use in fish disease treatment and prevention, as well as in the food, medicine, and cosmetics industries.

Page 8 - Orchard Massilia strains that produce violacein substances discovered Use of fish disease prevention and treatment... Expansion of areas such as food The National Institute of Fisheries Science (Director Dong-shik Woo) announced on the 16th that it had discovered a new microorganism that produces 'violacein', a substance that can suppress the scutica worm that causes the mass death of halibut. Scotika is a parasite that causes scutica disease. After securing and isolating a variety of microorganisms with antibacterial activity from a halibut farm, the orchard discovered a new microorganism called 'Massilia sp. NB-5' strain that produces a useful substance called violacein. In addition, he deciphered the genome of this strain consisting of 6.25 million base pairs, and revealed how violacein is made from the information of each gene. Violacein produced by this new strain of Massilia was found to have excellent antibacterial activity against scutica and also high ...
