Lasiodiplodia theobromae GK-1, a strain of filamentous fungi isolated from the surface of fruit of the coconut palm, produced a coconut-like aroma in potato-dextrose-agar medium. As the compound most responsible for the aroma, 2-octeno-δ-lactone was identified. Comparing to (R)-2-deceno-δ-lactone, its stereochemistry was found to be 100% of R-configuration by using gas chromatographic enantiomeric separation after converting the lactone to lactol methyl ethers. Mellein and β-phenylethanol were found in the early stages of the culture. Degradative process of δ-lactones by the strain GK-1 was also investigated.
