Abstract
Trapping by adsorption on hydrophobic porous polymers was used to selectively remove γ-decalactone from the complex bioconversion medium. Several sorbents were tested : activated carbon, and three porous polystyrene-type polymers (Porapak Q, Chromosorb 105, and Resin SM4). The sorption isotherms were determined in water and in a model bioconversion medium without microorganisms. In the last part of the study, the application to the production of γ-decalactone by Sporidiobolus salmonicolor was carried out. Hydrophobic porous adsorbents are compatible with the bioconversion and protect the yeast from the toxic effect of γ-decalactone.
