Poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate)-based biopolymer systems
Biochemistry (Moscow) Supplement Series B: Biomedical Chemistry, 2011Biodegradable biopolymers attract much attention in biology and medicine due to its wide application. The present review considers a biodegradable and biocompatible polymer of bacterial origin, poly(3-hydroxybutyrate), which has wide perspectives in medicine and pharmaceutics.

Anaerobic degradation of poly-3-hydroxybutyrate and poly-3-hydroxybutyrate-co-3-hydroxyvalerate
Biodegradation, 1997The anaerobic degradation of the polyesters poly-3-hydroxybutyrate (PHB) and poly-3-hydroxybutyrate-co-3-hydroxyvalerate (PHBV) was investigated with special regard to intermediate products, kinetics, and yields. During the degradation of PHBV acetate, propionate, n-butyrate, and n-valerate were detected.

AbstractThe thermal decomposition mechanism of maleated poly(3‐hydroxybutyrate) (PHB) was investigated by FTIR and 1H NMR. The results of experiments showed that the random chain scission of maleated PHB obeyed the six‐membered ring ester decomposition process.

Polyhydroxyalkanoates (PHAs) represent a group of biopolymers that are synthesized by many bacteria as storage compounds and deposited as insoluble cytoplasmic inclusions. Because they have many putative technical and medical applications, PHAs may play an important role in human life in the future.

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, 2010Abstract 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.

Biodegradable poly‐3‐hydroxybutyrate as a fertiliser carrier
Journal of the Science of Food and Agriculture, 2016AbstractBACKGROUNDIncreasing use of mineral fertilisers can lead to accumulation of fertilisers in soil, water and foodstuffs. One of the approaches to preventing these problems is to develop controlled release forms of fertilisers.RESULTSExperimental formulations of the nitrogen fertiliser urea loaded in a degradable matrix of the natural polymer poly‐

Phase behavior of poly(3-hydroxybutyrate)/poly(3-hydroxybutyrate-co-3-hydroxyvalerate) blends
Fluid Phase Equilibria, 2007Miscibility, molecular interactions and crystallinity of blends of poly(3-hydroxybutyrate) [P(3HB)] with poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [P(3HB-co-3HV)] were studied in this work. P(3HB)/P(3HB-co-3HV)-6%3HV blends were prepared by casting and characterized by differential scanning calorimetry (DSC) and X-ray diffraction (XRD).
