Thermoplastic polyurethane (TPU) has been used to toughen Poly (3-hydroxybutyrate-co-4-hydroxybutyrate) (P34HB) and increase its cold-resistance. The compatibility of P34HB/TPU blends was predicted by solubility parameter, then investigated by appearance and transparence, Dynamic Mechanical Analysis (DMA) and Scanning Electron Microscopy (SEM) analysis.

A recombinant Escherichia coli strain has been developed that produces poly(3-hydroxybutyrate-co-4-hydroxybutyrate) when grown in complex medium containing glucose. This has been accomplished by introducing into E. coli DH5 alpha separate plasmids harboring the polyhydroxyalkanoate (PHA) biosynthesis genes from Ralstonia eutropha (formerly named ...

In the present work, a series of Zein/Poly(3-hydroxybutyrate-co-4-hydroxybutyrate) blend fiber scaffolds have been prepared by electrospinning method. The electrospun fibers showed a circular and uniform morphology with random distribution. The blend fiber scaffolds possessed well interconnected porous fibrous network structure with high porosity and ...

Membranes used in guided bone regeneration (GBR) are required to exhibit high mechanical strength, biocompatibility, biodegradation, osteogenic and osteoinductive potential. In our study, poly(3-hydroxybutyrate-co-4-hydroxybutyrate)(P(3HB-co-4HB))/octacalcium phosphate (OCP) (P(3HB-co-4HB)/OCP) nanofibrous membranes were fabricated by electrospinning ...

Poly(3-hydroxybutyrate-co-4-hydroxybutyrate), short as P(3HB-co-4HB), was successfully produced by engineered Halomonas bluephagenesis TD01 grown in glucose and γ-butyrolactone under open non-sterile conditions. Gene orfZ encoding 4HB-CoA transferase of Clostridium kluyveri was integrated into the genome to achieve P(3HB-co-4HB) accumulation comparable

Random copolymers of 3-hydroxybutyrate (3HB) and 4-hydroxybutyrate (4HB) with a wide range of compositions varying from 0 to 83 mol% 4HB were produced by Alcaligenes latus from the mixed carbon substrates of 3-hydroxybutyric and 4-hydroxybutyric acids.

Solution-grown single crystals of poly(3-hydroxybutyrate-co-4-hydroxybutyrate) [P(3HB-co-4HB)] were hydrolyzed by polyhydroxybutyrate (PHB) depolymerase from Ralstonia pickettii T1. Enzymatic degradation proceeded from the edges of lamellar crystals, yielding serrated contour and small crystal fragments.
