Many isolated strains of Aureobasidium sp. were found to produce extracellular lipids as heavy oils in culture media containing no CaCO3 as a neutralizing agent. The lipids (35 g) were recovered from the culture broth (1 liter) of a light-colored mutant of Aureobasidium sp. A-2 and proved to be a mixture of fatty acid esters of arabitol and mannitol. The two main components of the lipophilic moiety of the lipids proved to be 3,5-dihydroxydecanoic and 5-hydroxy-2-decenoic acids by the identification of their lactones, (+)-3-hydroxydecan-5-olide and (R)-(−)-2-decen-5-olide, that is, R-(−)-massoilactone, respectively.
