Abstract

La présente invention concerne des procédés de fermentation efficaces et économiques pour la production efficace de poly-3-hydroxyalcanoates (PHA) à chaîne moyenne, comprenant la croissance de micro-organismes de production de PHA en utilisant des huiles végétales comme source de carbone, en présence ou en l’absence de saccharide. Les procédés selon l’invention comprennent la production de biomasse en culture discontinue, la production ultérieure de biomasse en culture à écoulement discontinu par l’ajout de saccharide et d’une source d’azote au milieu de culture et enfin la production de PHA par l’ajout d’huile végétale comme source de carbone avec limitation d’azote ou de phosphore. Grâce au procédé selon l’invention, au moins 90% en poids sec des PHA à chaîne moyenne par rapport à la biomasse sèche est obtenu à partir du milieu de culture, présentant entre 5 et 10% d’unités monomères à chaîne moyenne dans leur structure.
