Abstract
The invention relates to a fed batch production process for a composition of sophorosides, in which culturing takes place of at least one Candida bombicola or Candida apicola strain and the cultured strain is exposed in a reaction zone to an excess sugar supply and a continuous supply of at least one appropriate substrate at a supply rate to the reaction zone between 0.01 and 4 grams per hour and per liter of initial reaction volume and for a supply time such that the residual concentration of the substrate in the reaction zone is maintained at a value at the most equal to 18 grams per liter of initial reaction volume for the supply time and the composition of sophorosides produced is recovered.
