Synthese und Abbau von Biopolymeren. T. 1: Verfahren zur biotechnischen Darstellung natuerlicher Thermoplaste und Elastomere und ihr biologischer Abbau Abschlussbericht

The homopolyester poly (3-hydroxyvaleric acid) was produced by fermentation with chromobacterium violaceum, and polyesters were prepared containing 4-hydroxyvaleric acid obtained from levulinic acid using a genetically modified strain of Pseudomonas putida. The physical properties of these polyesters have been characterized and their technical usability is shown. In general, polyhydroxyfatty acids (PHF) are easily subjected to biodegradation. In a feasibility study on the market potential of novel PHF if is supposed that by agricultural production with transgenic plants exprimizing the bacterial genes for polyester biosynthesis, the costs of PHF may be reduced to 1 DM/kg.
