PURPOSE: Streptococcus dysgalactiae ID9103 and a method for producing hyaluronic acid using the same are provided to effectively obtain high molecular hyaluronic acid by culturing in a medium containing a carbon source and a nitrogen source. CONSTITUTION: A Streptococcus dysgalactiae ID9103 has deposit number KCTC11818BP. A method for producing hyaluronic acid comprises a step of culturing the strain in a medium containing a carbon source and a nitrogen source. The carbon source is selected from the group consisting of glucose, fructose, lactose, maltose, galactose, glycerol, and a mixture thereof. The nitrogen source is selected from the group consisting of a yeast extract, casein peptone, casein acid lysate, casein enzyme lysate, Bacto peptone, casitone, neopeptone, and a mixture thereof.
