A method for isolating one compound or more than one compound from a biomass which contains microorganisms that have produced the compound or compounds, the method comprising the following steps: (a) preparing or obtaining wet cells having an average moisture content of between 30% and 80%; (b) subjecting the wet cells to primary drying to obtain primary dried cells having an average moisture content of between 5% and 50%; (c) subjecting the primary dried cells obtained in (b) to secondary drying to obtain secondary dried cells having an average moisture content of no greater than 10%; and (d) extracting or isolating, purifying and/or refining the compound or each of the compounds from the secondary dried cells obtained in (c) .
L'invention porte sur un procédé qui permet d'isoler au moins un composé d'une biomasse contenant des microorganismes destinés à la production du ou des composés, lequel procédé consiste à: (a) préparer ou obtenir des cellules humides d'une teneur moyenne en humidité comprise entre 30 % et 80 %; (b) soumettre les cellules humides à un séchage primaire afin d'obtenir des cellules séchées primaires d'une teneur moyenne en humidité comprise entre 5 % et 50 %; (c) soumettre les cellules séchées primaires obtenues sous (b) à un séchage secondaire afin d'obtenir des cellules séchées secondaires d'une teneur moyenne en humidité inférieure ou égale à 10 %; et (d) extraire ou isoler, purifier et/ou raffiner le composé ou chacun des composés issus des cellules séchées secondaires obtenues sous (c).
