Abstract :	[en] During the biotransformation of castor oil into -decalactone, R. aurantiaca produced both the lactone form and its precursor (4-hydroxydecanoic acid). After six days of culture, a maximum yield of -decalactone of 6.5 g/l was obtained. The parameters of -decalactone adsorption on three Macronet resins (MN-202, MN-102 and MN-100) were investigated in water. Adsorption isotherms of -decalactone for the three Macronet resins were linear. The trapping of -decalactone produced by R. aurantiaca on these resins was then carried out. -Decalactone was eVectively retained by all the studied Macronet resins. The resin MN-202 trapped -decalactone more eYciently than MN-102 and MN-100. The percentages of -decalactone adsorbed on the resins MN-202, MN-102 and MN-100 were, respectively, 85, 75 and 81%, whereas around 70% of the adsorbed -decalactone was then desorbed. We propose an industrial process that uses Macronet resins to extract -decalactone from culture broth of R. aurantiaca.
