Abstract

A process for the production of polymer containing units of the formula -O.CH(CH3)CH2CO- wherein a microorganism that is capable of accumulating a poly---hydroxy-butanoic acid is cultivated in an aqueous medium characterised in that, at least during part of the period when polyester is being accumulated, the substrate comprises an organic acid, or derivative thereof as assimilable carbon source and assimilable sources of nitrogen and phosphorus. In order to increase thermoplasticity due to lowering crystallinity and crispness thereof cultivation is carried out up to complete assimilation of nitrogen and/or phosphorus.
