  • Method of treatment of flocculated homogenate of microbial cells containing glucose isomerase
    Patent number: 4242451
    Abstract: This application concerns a method for treating a flocculated homogenate of whole cell glucose isomerase derived from the microorganism Actinoplanes so that the preparation can be dried, preferably after being extruded into cylindrically-shaped particles. The critical step in this method is the addition of a water absorbing smectite filler to the flocculated homogenate prior to drying. The floc also may be frozen and thawed prior to addition of the filler.

  • Media containing molasses and soy flour for producing glucose isomerase and method
    Patent number: 4003793
    Abstract: This disclosure relates to an improved medium for growing organisms (preferably Actinoplanes missouriensis) which produce glucose isomerase. Use of the medium results in increased yields of enzyme in shorter fermentation times. The improved medium contains molasses and particulate soy material, preferably soy flour.

  • Media containing molasses and corn steep liquor for producing glucose isomerase from Actinoplanes and method
    Patent number: 3992262
    Abstract: This disclosure relates to an improved medium for growing organisms (preferably Actinoplanes missouriensis) which produce glucose isomerase. Use of the medium results in increased yields of enzyme in shorter fermentation times. The improved medium contains molasses, corn steep liquor, and an inorganic nitrogen salt.
