Piezoelectric 3-D Fibrous Poly(3-hydroxybutyrate)-Based Scaffolds Ultrasound-Mineralized with Calcium Carbonate for Bone Tissue Engineering: Inorganic Phase Formation, Osteoblast Cell Adhesion, and Proliferation.

ACS Applied Materials and Interfaces, 2019
Elaboration of novel biocomposites providing simultaneously both biodegradability and stimulated bone tissue repair is essential for regenerative medicine. In particular, piezoelectric biocomposites are attractive because of a possibility to electrically

Chromosome engineering of the TCA cycle in Halomonas bluephagenesis for production of copolymers of 3-hydroxybutyrate and 3-hydroxyvalerate (PHBV).

Metabolic Engineering, 2019
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is a promising biopolyester with good mechanical properties and biodegradability. Large-scale production of PHBV is still hindered by the high production cost.

Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) production from engineered Ralstonia eutropha using synthetic and anaerobically digested food waste derived volatile fatty acids.

International Journal of Biological Macromolecules, 2019
Ralstonia eutropha Re2133/pCB81 is able to utilize various volatile fatty acids (VFAs) (acetate, butyrate, lactate, and propionate) for polyhydroxyalkanoates (PHAs) production.

Nonisothermal crystallization and melting behavior of poly(3-hydroxybutyrate) and maleated poly(3-hydroxybutyrate)

European Polymer Journal, 2002
Nonisothermal crystallization and melting behavior of poly(3-hydroxybutyrate) (PHB) and maleated PHB were investigated by differential scanning calorimetry using various cooling rates. The results show that the crystallization behavior of maleated PHB from the melt greatly depends on cooling rates and its degree of grafting.

Photodegradation of poly(3-hydroxybutyrate)

Polymer Degradation and Stability, 2010
Abstract The effect of ultraviolet radiation on the properties of poly(3-hydroxybutyrate) (PHB) was studied. The PHB investigated is produced from microbial fermentation using saccharose from sugarcane as the carbon source to the bacteria. The material was exposed to artificial UV-A radiation for 3, 6, 9 and 12 weeks.

The Oxidation of 3‐Hydroxybutyrate in Developing Rat Jejunum

Journal of Pediatric Gastroenterology and Nutrition, 1991
SummaryKetone bodies and glutamine are the primary oxidative substrates in the intestine of fasting adult rats. Because suckling rats consume the majority of their calories in the form of lipid and as a result have elevated blood ketone concentrations similar to fasting adult rats, we examined the role of ketone oxidation as a source of energy in the ...

Flow-injection determination of 3-hydroxybutyrate in serum with an immobilized 3-hydroxybutyrate dehydrogenase reactor and fluorescence detection

Talanta, 1994
A flow-injection system with an immobilized enzyme reactor is proposed for the determination of 3-hydroxybutyrate. 3-Hydroxybutyrate dehydrogenase is immobilized on aminated poly(vinyl alcohol) beads and packed into a stainless-steel column (4 cm x 4 mm I.D.). Serum is diluted and filtered.

Characterization of two 3-hydroxybutyrate dehydrogenases in poly(3-hydroxybutyrate)-degradable bacterium, Ralstonia pickettii T1

Journal of Bioscience and Bioengineering, 2006
Two D-(-)-3-hydroxybutyrate (3HB) dehydrogenases, BDH1 and BDH2, were isolated and purified from a poly(3-hydroxybutyrate) (PHB)-degradable bacterium, Ralstonia pickettii T1. BDH1 activity increased in R. pickettii T1 cells grown on several organic acids as a carbon source but not on 3HB, whereas BDH2 activity markedly increased in the same cells grown

Smart Piezoelectric Nanohybrid of Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and Barium Titanate for Stimulated Cartilage Regeneration.

ACS Applied Bio Materials, 2019
Piezoelectric materials strive to articulate smart materials and transduce electric fields by applying mechanical pressure and vice versa. This study demarcates augmented cartilage regeneration from the praxis of the smart material intervention that ...
