[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.
