Abstract

PURPOSE:To stably, extremely raise productivity stably and to produce inexpen sively hyaluronic acid, by cultivating a bacterium capable of producing hyaluronic acid in a specific culture solution. CONSTITUTION:100-2,500 units/l lytic enzyme (e.g., lysozyme), 0.5-10g/l surface active agent (e.g., cetyltrimethylammonium bromide), glucose, KH2PO2, anti- foaming agent, etc. are added to a culture solution which is sterilized under heating and cooled to <=45 deg.C. A bacterium (e.g., Streptococcus pyogenes) capable of producing hyaluronic acid is inoculated into the culture solution, cultivated at 25-40 deg.C at 6.5-8.5pH for 1-2 days aerobically and hyaluronic acid formed and accumulated in the culture solution is separated and purified.

Hyaluronic acid exists as a component in connective tissues such as joints, vitreous body, ligaments, cartilage, skin, and bird crests, and plays important functions in maintaining tissue flexibility, maintaining structure, and regulating cell metabolism. Fulfilling. In addition, hyaluronic acid is a very large polymeric substance, and its solution has strong viscoelasticity and water-retaining properties, so it has a wide range of uses as cosmetics, wound treatment agents, eye medicines, and arthritis treatment agents.

However, since the hyaluronic acid obtained from these living organisms forms a complex with proteins and mucopolysaccharides such as chondroitin, a complicated process of separation and purification is required.
Furthermore, since hyaluronidase is often present in the mixture, the hyaluronic acid is decomposed during the extraction and purification steps, resulting in a decrease in molecular weight, resulting in a disadvantage of low viscosity and water retention. For this reason, an attempt to produce hyaluronic acid using culture method g2 has been disclosed in JP-A-58-56692.
