Poly $ = hydroxybutyrate ( PHB ) biosynthetic genes in Rhizobium meliloti 41
2 Dipartimento di Biotecnologie Agrarie, Universita di Padova, Via Gradenigo 6, 35131 Padova, Italy Genes encoding fiketothiolase (phaA), acetoacetyl-CoA reductase (phaB) and PHB-synthase (phaC) from R. meliloti 41, together with a fourth gene, referred to as ORF1, presumed to be involved in PHB biosynthesis, have been cloned and sequenced. phaA, phaB and ORFl were identified by heterologous hy...
متن کاملEffects of Poly-β-hydroxybutyrate (PHB) and PHB degrading bacteria (Acidovorax sp.) on the growth performance, body composition and bacterial metabolic activity in Siberian Sturgeon (Acipenser baerii) fingerlings
Five hundred and ninety two Siberian sturgeon fingerlings (average weight, 11.1±0.9 g) were randomly distributed in 16 tanks (150 L) at a density of 35 fish per tank and fed different treatments (Control, degrading bacteria, 2% PHB, degrading bacteria + 2%PHB) for 60 days. At the end of the experiment, no significant difference was observed in case of final weight in fingerlings but fish fed PH...
متن کاملAdsorption of Human Immunoglobulin G to Poly (β-hydroxybutyrate) (phb), Poly (l- Lactic Acid) (plla) and Phb/plla Blends
Biodegradable polymeric materials can be used as temporary implants and may be able to carry out specific functions for a pre-determined period prior to their degradation in vivo. In order to be used they must present characteristics of biocompatibility. When a material comes into contact with blood, the instantaneous adsorption of protein occurs on its surface. Coverage of the surface by γ-glo...
متن کاملThe "intracellular" poly(3-hydroxybutyrate) (PHB) depolymerase of Rhodospirillum rubrum is a periplasm-located protein with specificity for native PHB and with structural similarity to extracellular PHB depolymerases.
Rhodospirillum rubrum possesses a putative intracellular poly(3-hydroxybutyrate) (PHB) depolymerase system consisting of a soluble PHB depolymerase, a heat-stable activator, and a 3-hydroxybutyrate dimer hydrolase (J. M. Merrick and M. Doudoroff, J. Bacteriol. 88:60-71, 1964). In this study we reinvestigated the soluble R. rubrum PHB depolymerase (PhaZ1). It turned out that PhaZ1 is a novel typ...
