Abstract
Hyaluronic acid can be produced efficiently and economically by culturing a strain belonging to a Streptococcus, which has hyaluronic acid producing ability, is hyaluronidase-nonproductive and shows anhemolytic property, and then collecting the hyaluronic acid from the resultant culture. The strain may preferably be Streptococcus zooepidemicus, especially, Streptococcus zooepidemicus YIT 2030 (FERM BP-1305). The hyaluronic acid has a high molecular weight and is useful in providing a cosmetic composition having excellent moisturizing effects and superb feeling of application.
