  • Production of glucose isomerase
    Patent number: 4059489
    Abstract: A process for the continuous production of glucose isomerase by maintaining a nutrient in the culture medium at a concentration which is limiting to growth. Preferably the growth limiting nutrient is the carbon source. The invention also covers a process for isomerizing glucose to fructose using continuously prepared glucose isomerase. Important conditions for culturing the glucose isomerase producing microorganism are the dissolved oxygen tension and dilution rate.

  • Process for the preparation of glucose isomerase using Curtobacterium
    Patent number: 4053361
    Abstract: The production of glucose-isomerizing enzyme by culturing a microorganism of the genus Curtobacterium (defined by K Yamada and K Komagata in J Gen Appl Microbiol., 18, 417-31 (1972) at pages 424-5 in a medium containing appropriate nutrients. The Curtobacterium strains which may be used include novel strains NCIB 11072 (NRRL B-8069) and NCIB (NRRL B-8068). The enzyme is used in a process for converting glucose to fructose.
