Abstract

L'invention concerne un procédé pour extraire le polyhydroxyalkanoate (PHA) d'une solution qui comporte un solvant et le PHA, ce procédé comprenant les opérations suivantes: (i) porter la solution à une première température; (ii) refroidir la solution pour la porter à une deuxième température, propice à la précipitation du PHA, et procéder simultanément au cisaillement de la solution, afin d'obtenir un PHA précipité, sensiblement exempt de gélification; et (iii) recueillir le PHA précipité. Selon un mode de réalisation apparenté du procédé, on peut obtenir la solution comme suit: (a) constituer une biomasse dotée d'un PHA intracellulaire; et (b) dissoudre le PHA en utilisant un solvant et en appliquant une première température propice à la dissolution du PHA.
