Streptococcus disgalactier ID9103 strain and hyaluronic acid production method using the same (Streptococcus dysgalactiae ID9103 and methodfor production of hyaluronic acidizing thesame)

摘要

The present invention relates to a strain of the genus Streptococcus that produces high-molecular-weight hyaluronic acid in a high yield and a method for producing hyaluronic acid using the same, and more specifically, a strain of Streptococcus disgalactier ID9103 having a deposit number of KCTC11818BP and culturing the strain The present invention relates to a method for producing hyaluronic acid including the step of: The present invention provides a Streptococcus strain that produces high-molecular-weight hyaluronic acid in a high yield, and a method for producing hyaluronic acid using the same. The strain of the present invention can produce high-value-added polymeric hyaluronic acid in a high yield. According to the production method of the present invention, various ultra-high molecular hyaluronic acids can be produced depending on the composition of the medium. It is possible to produce ultra high molecular weight hyaluronic acid having an average molecular weight of 10 million Da or more at maximum.
