Özet:

 

Poly(3-hydroxy alkanoate)s (PHA)s are bacterial polyesters  that have, due to their biodegradability and biocompatibility,  attracted considerable industrial interest.  All the substrates used  in feeding Alcaligenes eutrophus and Pseudomonas oleovorans have been  reviewed as far as we know, and some more new substrates or mixtures  have been used in PHA production by microorganisms.  Alcaligenes  eutrophus was fed with 4-pentenoic acid, 2-hydroxy ethyl methacrylate  (HEMA), corn oil acids, linseed oil acids and limonene as well as  mixtures of acetic acid and glucose or lactose.  Either HEMA as a sole  carbon source or the mixture of glucose did not produce polyester;  limonene as a sole carbon source gave few dry cells and very few  mgl-1 Poly (3-hydroxy butyrate-co-3-hydroxy valerate)(PHBV)  containing 5 mol-% of hydroxy valerate (HV) units.  Poly(3-hydroxy  butyrate), (PHB), was obtained from corn oil acids and the mixture of  glucose (15 gl-1) and acetic acid (2.5 gl-1); Poly (3-hydroxy  butyrate-co-3-hydroxy valerate) (PHBV) was obtained in moderate yield  from 4-pentenoic acid as a sole carbon source and the rest of the  substrates above.  Pseudomonas oleovorans was fed with linoleic acid,  laurel seed oil acids, corn oil acids, laurel leaf oil, rose oil and  limonene.  Medium chain length polyesters were obtained from linoleic  acid, corn oil acids and laurel seed oil acids, but the others did not  give any detectable polyester.  The polymers obtained were  characterized by size exclusion chromatography, 1H and 13C NMR,  FT-IR, thermal analysis and fast atom bombardment-mass spectrometer  techniques.
