Abstract

PURPOSE:To obtain the titled compound useful as an antiviral, antitumor, antifungal, antimicrobial agents and a remedy for psoriasis, by cultivating a variant strain of the genus Penicillium capable of promoting the growth by myoinositol. CONSTITUTION:A variant strain, belonging to the genus Penicillium, and capable of producing mycophenolic acid and promoting the growth thereof by myoinositol, preferably Penicillium brevi-compactum AJ117122 FERM-P No.7291 or AJ117123 FERM-P No.7292 is cultivated in a culture medium preferably under aerobic conditions by the submerged culture method at 25-28 deg.C for 170-450hr to give the aimed substance. For example, the above-mentioned variant strain is obtained by subjecting spores of Penicillium stoloniferum ATCC 10111, etc. as a parent strain to variation induction operation.

The present inventors have conducted various studies with the aim of breeding mycophenolic acid-producing bacteria that have a high ability to produce cimicotenoic acid. As a result, the present inventors have found that mycophenolic acid-producing bacteria belonging to the genus Penicillium have been successfully developed to play the role of myo-inositol. They discovered that a mutant strain in which the production of mycophenolic acid is delayed produces and accumulates mycophenolic acid, leading to the completion of the present invention.
