Starch-Filled PHB and PHB/HV Copolymer

Polymer International, 1996
The structure and mechanical properties of melt-pressed sheets of bacterially produced poly-3-hydroxybutyrate (PHB) and poly-3-hydroxybutyrate-co-3-hydroxyvalerate (PHB/HV) filled with various amounts of particulate maize starch granules have been investigated.

PHA/PHB

2011
Polyhydroxyalkanoates (PHAs) are a family of bacterially synthesized biopolyesters with biodegradability, biocompatibility, thermoprocessibilty, and flexible strengths. Poly-(R)-3-hydroxybutyrate (PHB) was the first PHA discovered and has been the best-studied PHA member.

Study on Synthesis of PHB by Moderate Halophile and Aqueous Extraction of PHB

Applied Mechanics and Materials, 2013
PHB (Poly-β-hydroxybutyrate) has been widely in the areas of industrial packaging, pharmacy and agriculture. Currently, its production cost, especially in extraction and purification are high. A moderate halophilic bacterium was used for PHB synthesis and an aqueous extraction method based on osmotic downshock was investigated in this paper to further ...

Improvement of polyhydroxybutyrate (PHB) plate-based screening method for PHB degrading bacteria using cell-grown amorphous PHB and recovered by sodium dodecyl sulfate (SDS).

International Journal of Biological Macromolecules, 2021
Poly(3-hydroxybutyrate) (PHB) is a biobased and biodegradable plastic. Considering the environmental issues of petroleum-based plastics, PHB is promising as it can be degraded in a relatively short time by bacteria to water and carbon dioxide ...

Hydrolysis of native poly(hydroxybutyrate) granules (PHB), crystalline PHB, and artificial amorphous PHB granules by intracellular and extracellular depolymerases

International Journal of Biological Macromolecules, 1999
Native poly(hydroxybutyrate) (PHB) granules, purified PHB and artificial amorphous PHB granules were examined as putative substrates for hydrolysis by the intracellular depolymerase system of Rhodospirillum rubrum and the extracellular depolymerase of Pseudomonas lemoignei. The R.

Biodegradability of Thermally Aged PHB, PHB-V, and PCL in Soil Compostage

Journal of Polymers and the Environment, 2004
The biodegradability of poly-β-hydroxybutyrate (PHB), poly-β-hydroxybutyrate-co-valerate (PHB-V) and poly-ɛ-caprolactone (PCL) were examined following thermal aging in an oven for 192, 425 and 600 h. Different temperatures, 100, 120 and 140°C for PHB and PHB-V and 30, 40 and 50oC for PCL were used to assess the influence of this parameter on ...
