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.
Claims7
A method for producing a composition selected from the group consisting of glucose isomerase enzyme and enzyme preparations containing glucose isomerase by culturing a microorganism of the Curtobacterium genus capable of producing the composition in a medium containing a carbon source and inorganic nutrients and recovering the composition.
A method for producing a composition selected from the group consisting of glucose isomerase enzyme and enzyme preparations containing glucose isomerase by culturing a micro-organism which is selected from the group consisting of Curtobacterium strain NRRL B-8069, Curtobacterium strain NRRL B-8068 and variants and mutants of said strains in a medium containing a carbon source and inorganic nutrients, and recovering the composition.
