Definitions
- the inventors of the present invention found that the recombinant bacterial strains which contain and express at least one fragment of the Thiocapsa pfenigii PHF synthase gene are also capable of 5-hydroxyhexanoic acid, its salts, esters and lactones into a copolyester biosynthesized by these bacteria.
- 5-Hydroxyhexanoic acid was prepared starting from 4-acetoacetic acid, which was quantitatively reduced with NaBH4.
- 5-Hydroxyhexanoic acid (5HHx) as a building block was detected by gas chromatography after methanolysis both in lyophilized cells and in isolated and purified polyester.
- the copolyesters obtained according to the invention are easy to process as thermoplastics and can be used in a variety of ways.
- thermoplastics for example in surgery for objects for wound closure, for example as suture material or staples or the like, as a fastening element for bones, for example fixation pins, plates, screws, dowels, as separating, filling or covering material, for example in the form of tissue, fleece, Cotton wool.
- the polyesters according to the invention can be used in pharmaceutical galenics, for example as auxiliaries, carrier materials, release systems for pharmaceuticals or for the encapsulation and / or microencapsulation of substances and active ingredients.
- biodegradable packaging materials such as foils, bottles, ampoules, cans, bags, boxes, boxes or the like, is possible using the present invention.
- Allowing the recombinant bacteria to grow up with cell densities of up to 100 g dry cell mass per liter of bacterial nutrient medium according to claim 7 has the advantage that relatively small volumes contain a considerable biomass and thus significantly increase productivity with appropriate dimensioning of large-scale plants than lower cell densities.
- the analysis of the polymer accumulated by the cells showed a polyester content of approx. 37 percent by weight of the cell dry matter.
- the polymer consisted of approx. 37 mol% 3-hydroxybutyric acid, approx. 50 mol% 3-hydroxyvaleric acid and approx. 13 mol% 4-hydroxyvaleric acid.
- a copolyester of the formula poly (3HB-co-3HHx-co-4HHx) could be produced, the analytical data of which are reproduced below.
- the polyesters had the analytical data shown below, where "A” represents the 13 C-NMR spectrum and "B” the * H-NMR spectrum.
- the signal assignment results from the numbering given in the structural formula of poly (3HB-co-3HHx-co-4HHx) shown.
- the gas chromatogram after methanolysis is then shown.
