Studies on Growth Inhibition of Hiochi-bacteria, Specific Saprophytes of Sake

Part. VI Muta-aspergillic Acid as a New Growth Inhibitant against Hiochi-bacteria

Abstract

A new growth inhibitant against hiochi-bacteria, C₁₁H₁₈N₂O, m.p. 173-4°C, named muta-aspergillic acid, has been isolated from the crystals of crude hydroxyaspergillic acid, obtained from culture filtrate of Asp. oryzae. Successful separation of these two compounds from each other was accomplished by counter current distribution method. The physical and chemical properties of muta-aspergillic acid as well as its physiological properties are described.
