  • High molecular weight sodium hyaluronate
    Patent number: 4784990
    Abstract: A novel mutant microorganism Streptococcus zooepidemicus HA-116 ATCC 39920, has been produced. The microorganism produces large amounts of high molecular weight hyaluronic acid. The invention provides a method of obtaining such microorganisms.The invention also concerns a method of obtaining sodium hyaluronate which comprises growing with vigorous agitation a microorganism of the genus Streptococcus under appropriate conditions in a suitable nutrient medium containing a sugar component as a carbon source. The sugar component is present in a substantially constant concentration between 0.2 and 10 grams per liter. The medium has a substantially constant pH between about 6.0 and 7.5 and includes a substantially constant magnesium ion concentration above 0.05 grams per liter. The sodium hyaluronate excreted into the medium by the organism is purified using methods involving precipitation, redissolving and reprecipitating the hyaluronate.

  • Method for producing enzymatically active eucaryotic sod in bacteria
    Patent number: 4742004
    Abstract: A method of producing enzymatically active eucaryotic superoxide dismutase or an analog thereof in a bacterial cell which contains and is capable of expressing a DNA sequence encoding the superoxide dismutase or analog thereof comprising maintaining the bacterial cell under suitable conditions and in a suitable production medium. The production medium is supplemented with an amount of Cu++ so that the concentration of Cu++ in the medium is greater than about about 2 ppm.The invention also concerns methods of recovering purified enzymatically active eucaryotic superoxide dismutase or analogs from bacterial cells producing the superoxide dismutase or analog.
