A comparative investigation of biodegradable polyhydroxyalkanoate films as matrices for in vitro cell cultures [Text] / E. I. Shishatskaya, T. G. Volova // J. Mater. Sci.-Mater. Med. - 2004. - Vol. 15, Is. 8. - P915-923, DOI 10.1023/B:JMSM.0000036280.98763.c1. - Cited References: 34 . - 9. - ISSN 0957-4530

Аннотация: The paper describes the production and investigation of flexible films made of high-purity polyhydroxyalkanoates (PHAs) - polyhydroxybutyrate [poly-(3HB)] and poly-3-hydroxybutyrate-co-poly-3-hydroxyvalerate [poly(3Hl3-co-3HV)], containing 4-30 mol % hydroxyvalerate. Poly(3HB-co-3HV) films have a more porous structure than poly-(3HB) films, which are more compact, but their surface properties, such as wettability and surface and interface energies, are the same. Sterilisation of the PHA films by conventional methods (heat treatment and gamma-irradiation) did not impair their strength. Cells cultured on PHA films exhibited high levels of cell adhesion. Cell morphology, protein synthesis and DNA synthesis were estimated by extent of H-3-thymidine incorporation into the animal cell cultures of various origins (fibroblasts, endothelium cells, and isolated hepatocytes) in direct contact with PHAs. The investigation showed that this material can be used to make matrices for in vitro proliferous cells. The investigated properties of poly-(3HB) and poly(3HB-co-3HV) films proved to be fundamentally similar. (C) 2004 Kluwer Academic Publishers.

Dynamics of activity of the key enzymes of polyhydroxyalkanoate metabolism in Ralstonia eutropha B5786 [Text] / T. G. Volova [et al.] // Appl. Biochem. Microbiol. - 2004. - Vol. 40, Is. 2. - P. 170-177, DOI 10.1023/B:ABIM.0000018921.04863.d5. - Cited References: 27 . - ISSN 0003-6838

Аннотация: The dynamics of accumulation of polyhydroxybutyrate (PHB) and the activities of key enzymes of PHB metabolism (beta-ketothiolase, acetoacetyl-CoA reductase, PHB synthase, D-hydroxybutyrate dehydrogenase, and PHB depolymerase) in the hydrogen bacterium Ralstonia eutropha B5786 were studied under various conditions of carbon nutrition and substrate availability. The highest activities of beta-ketothiolase, acetoacetyl-CoA reductase, and PHB synthase were recorded during acceleration of PHB synthesis. The activities of enzymes catalyzing PHB depolymerization (PHB depolymerase and D-hydroxybutyrate dehydrogenase) were low, being expressed only upon stimulated endogenous PHB degradation. The change of carbon source (CO2 or fructose) did not affect the time course of the enzyme activity significantly.
