Abstract
The invention relates to a microbiological process for the production of polyesters and utilizes bacteria of the Pseudomanas fluorescens rRNA branch according to the phylogenetic classification of De Vos and De Ley. These bacteria are cultured under aerobic fermentation conditions in a nutrient medium comprising an excess of at least one assimilarable acylic aliphatic hydrocarbon compound having 6-18 carbon atoms and a limiting quantity of at least one of other nutrients essential for growth to form poly-3-hydroxyalkanaoates.
