Physiological-biochemical properties and the ability to synthesize polyhydroxyalkanoates of the glucose-utilizing strain of the hydrogen bacterium Ralstonia eutropha B8562 / T. G. Volova [et al.] // Applied Microbiology and Biotechnology. - 2006. - Vol. 73, Is. 3. - P429-433, DOI 10.1007/s00253-006-0460-0 . - ISSN 0175-7598

Аннотация: Physiological-biochemical, genetic, and cultural properties of the glucose-utilizing mutant strain Ralstonia eutropha B8562 have been compared with those of its parent strain R. eutropha B5786. It has been shown that growth characteristics of the strain cultured on glucose as the sole carbon and energy source are comparable with those of the parent strain. Strain B8562 is characterized by high polyhydroxyalkanoate (PHA) yields on different carbon sources (CO2, fructose, and glucose). PHA accumulation in the strain batch cultured on glucose under nitrogen deficiency reaches 90 %. The major monomer in the PHA is ?-hydroxybutyric acid (more than 99 mol %); the identified minor components are ?-hydroxyvaleric acid (0.25-0.72 mol %) and ?-hydroxyhexanoic acid (0.08-1.5 mol %). The strain is a promising PHA producer on available sugar-containing media with glucose. В© Springer-Verlag 2006.

Аннотация: The dynamics of accumulation of polyhydroxybutyrate (PHB) and the activities of the key enzymes of PHB metabolism (beta-ketothiolase, acetoacetyl-CoA reductase, PHA synthase, D-hydroxybutyrate dehydrogenase, and PHA 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 PHA synthase were recorded at the stage of acceleration of PHB synthesis. The activities of enzymes catalyzing PHB depolymerization (PHB depolymerase and D-hydroxybutyrate dehydrogenase) were low, being expressed only at stimulated endogenous PHB degradation. The change of carbon source (CO2 or fructose) did not cause any marked changes in the time course of enzyme activity.

Аннотация: As intracellular carbon and energy storage materials, polyhydroxyalkanoates (PHA) are a diverse biopolyesters synthesized by many bacteria. PHA have been produced in large quantity for various application research including medical implants for approximately 30 years. Many studies demonstrated that PHA are promising implant materials due to their diverse and ascendant mechanical, biodegradable and tissue compatible properties. Importantly, common PHA biodegradation products including oligomers and monomers are also not toxic to the cells and tissues. Pharmaceutical applications of some PHA degradation products also have been reported. So far, no study has been reported to have any carcinogenesis result induced by any PHA or their biodegradation products. All results suggest that PHA could be developed into various bio-implant products.
