Production of Odoriferous γ Lactones by Fusarium poae

Abstract

Cultured malt broth of Fusarium poae has a strong fruity odor mainly due to lactones: γ penta-, γ hexa-, γ hepta-, γ octa-, γ nona-, γ deea-, γ undeea-, γ dodeca-, cis-6-dodecen-4-olide and δ decalactones. They were identified after gas chromatography and mass spectrometry by comparison of retention data and odors with those of authentic samples. cis-6-Dodecen-4-olide is the most abundant lactone (2 mg/liter) and is responsible for the predominant canned peach-like aroma.
