Fabrication of chitin/poly(3-hydroxybutyrate-co-3-hydroxyvalerate) hydrogel scaffold
Carbohydrate Polymers, 2012Regeneration of skin after a large area wound or burn is often difficult without the aid of a scaffold. In this work we developed a 3D macroporous chitin/poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) hydrogel blend by normal solution chemistry and lyophilized it to get the scaffold.

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) production by Haloarchaeon Halogranum amylolyticum
Applied Microbiology and Biotechnology, 2015Haloarchaea is an important group of polyhydroxyalkanoate (PHA)-accumulating organisms. However, few promising haloarchaeal species for economical and efficient PHA production have been reported. Here, we first discovered that Halogranum amylolyticum TNN58 could efficiently accumulate poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with a high 3 ...

In this study, a phaCR gene encoding PHA synthase was identified in Rhodoligotrophos defluvii which was adjacent to β-ketothiolase encoded by phaAR gene and acetoacetyl-CoA reductase encoded by phaBR gene. Amino acid comparison of PhaCR showed the highest homology of 65.98% with PhaC of R.

Biodegradability of poly (3-hydroxybutyrate-co-3-hydroxyvalerate) in activated sludge
Chemosphere, 1992Abstract The biodegradability of microbial copolyester of 3-hydroxybutyrate and 3-hydroxyvalerate, P(3HB-co-3HV), in activated sludge was studied by MITI test method to examine the applicability of the test to biodegradable plastics. The biodegradability after 28 days was 88% under standard condition and did not vary with the particle size of test ...

Cocrystallization of isothermally crystallized poly(3-hydroxybutyrate-co-3-hydroxyvalerate)
Macromolecules, 1992The crystalline lattices of random poly(3-hydroxybutyrate-co-3-hydroxyvalerate) were found to be independent of the crystallization temperature, whereas the composition in the crystalline phase changes. The rise in the crystallization temperature is accompanied by the decrease in the content of minor comonomer units in the crystalline phase.

Complex composition distribution of poly(3-hydroxybutyrate-co-3-hydroxyvalerate)
Macromolecules, 1995Four commercially available samples of bacterial poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [P(3HB-co-3HV)] containing from 6.5 to 21.8 mol % 3HV have been fractionated by chloroform/n-heptane mixed solvent. They have been separated into several fractions with wide composition ranges.

It is proposed that melt-extrusion of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) at varying processing temperatures and screw speeds causes changes in the atomic positioning of the oxygen atoms in the helix structure due to torsion of the main chain bonds.

Miscibility of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and poly(vinyl chloride) blends
Polymer, 1995Abstract The miscibility behaviour of biodegradable poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHB-HV) blended with poly(vinyl chloride) (PVC) was investigated by using differential scanning calorimetry, dynamic mechanical thermal analysis, Fourier-transform infra-red spectroscopy and a mechanical testing system. A blend of PHB-HV containing 8% HV

In this study, biodegradable poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films with 1.2-4.6 wt% of cellulose nanowhiskers (CNWs) were manufactured by solution casting using N,N-dimethylformide (DMF) as the solvent. Crystallization behaviors of PHBV/CNW composites were studied under isothermal conditions using differential scanning calorimetry ...
