Заглавие : Dynamics of activity of the key enzymes of polyhydroxyalkanoate metabolism in Ralstonia eutropha B5786
Место публикации : Applied Biochemistry and Microbiology. - 2004. - Vol. 40, Is. 2. - С. 170-177. - ISSN 00036838 (ISSN) , DOI 10.1023/B:ABIM.0000018921.04863.d5

Аннотация: The dynamics of accumulation of polyhydroxybutyrate (PHB) and the activities of key enzymes of PHB metabolism (?-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 ?-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.

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: The analysis of the literature on the methods of soluble organosolv lignins isolation, their physical-chemical study and on the method of their processing to porous aerogels and liquid hydrocarbons was carried out. A review of the literature allowed us to choice of the most important areas of research. For isolation from wood the soluble lignins free from sulfur the methods of catalytic peroxide delignification at mild conditions (temperature
