BACTERIUM CAPABLE OF PRODUCING PURINE SUBSTANCE, AND PROCESS FOR PRODUCTION OF PURINE SUBSTANCE

摘要

A purine-derived substance is produced by culturing a bacterium belonging to the genus Bacillus which has an ability to produce purine-derived substance and has been modified so that enzymatic activity of fructose bisphosphatase is decreased in a medium to cause accumulation of a purine-derived substance in the medium or cells, and collecting the purine-derived substance from the medium or cells.
