A sporogenic substance, named sporogen-AO 1, was isolated from the cultured broth of Aspergillus oryzae ; the fungus has been widely used in Japanese fermentation industry for producing Japanese traditional foods (sake, soy sause and miso) and also various useful enzymes. Sporogen-AO 1, isolated from an abundantly sporulating strain, exhibited significant sporulation-stimulating activity at a dose of 4.4μg/paper disc on the sparsely sporulating strain of the fungus. The structure was elucidated as the figure (1) on the basis of spectroscopic analysis. A new unknown sporogenic substance(65μg) has been isolated from the cultured broth(180 liters) of a different strain of Asp. oryzae. Improving the yield as well as its structure analysis is now under investigation.
