| description | A method or process for producing polyhydroxyalkanoates (PHAs) in biomass. The process entails feeding an organic carbon containing substrate to biomass enriched in PHA accumulating bacteria. Particularly the process entails intermittently supplying the substrate to the biomass at least three separate times over a selected period. The object of the process is to produce PHA having a relatively high molecular weight, at least 400,000 g/mole. By controlling the frequency at which the substrate is supplied to the biomass and by feeding a sufficient amount of the substrate to the biomass, the method or process produces the PHA having the relatively high molecular weight.
L'invention concerne un procédé ou un processus de production de polyhydroxyalcanoates (PHA) dans une biomasse. Le procédé implique l'alimentation par un substrat contenant du carbone organique d'une biomasse enrichie en bactéries accumulant les PHA. En particulier, le procédé implique l'apport intermittent du substrat à la biomasse au moins trois fois séparément sur une période déterminée. L'objectif du procédé est de produire des PHA de poids moléculaire relativement élevé, au moins 400 000 g/mole. En commandant la fréquence à laquelle le substrat est apporté à la biomasse et en alimentant la biomasse par une quantité suffisante de substrat, le procédé produit des PHA de poids moléculaire relativement élevé. |
