Starch-Filled PHB and PHB/HV Copolymer
Polymer International, 1996The 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.

PHB recovery by hypochlorite digestion of non-PHB biomass
Biotechnology Techniques, 1989Hypochlorite digestion of bacterial biomass from intracellular poly-β-hydroxybutyrate (PHB) has not been used on a large scale since it has been reported to severely degrade PHB. In this study, to minimize degradation, the initial biomass concentration, digestion time and pH of the hypochlorite solution were optimized.

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, 2013PHB (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 ...

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, 2004The 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 ...

The “PHB Depolymerase Inhibitor” of Paucimonas lemoignei Is a PHB Depolymerase
Biomacromolecules, 2002A approximately 35 kDa protein that has been described to be secreted by Paucimonas lemoignei during growth on succinate and to inhibit hydrolysis of denatured (crystalline) poly(3-hydroxybutyrate) (dPHB) by extracellular PHB depolymerases of P. lemoignei (PHB depolymerase inhibitor (PDI)) was purified and characterized.

2005 12th International Symposium on Electrets, 2006
Flexible standing films of piezoelectric composite made of lead zirconate titanate (PZT) ceramic powder and poly(3-hydroxybutyrate) (PHB) in powder form were obtained by mixing both polymers mechanically and pressed at 180 /spl deg/C. The piezoelectric coefficient d/sub 33/ were investigated as function of PZT content, poling temperature and electric ...

China has made rapid progress from fundamental research to industrial translation in polyhydroxyalkanoates (PHA) biomanufacturing, with polyhydroxybutyrate (PHB) and its copolymers as representative products. Propelled by the national "dual carbon" strategy, Chinese researchers and enterprises have developed unconventional halophilic chassis and next ...

Applied Microbiology and Biotechnology, 2018
The biodegradation of polyhydroxybutyrate (PHB) has been broadly investigated, but studies typically focus on a single strain or enzyme and little attention has been paid to comparing the interaction of different PHB depolymerase (PhaZ)-producing strains with this biopolymer.
