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‐

Abstract With the objective of developing new biodegradable materials, the miscibility and the crystallinity of blends of poly(3-hydroxybutyrate), P(3HB), and poly(3-hydroxybutyrate-co-3-hydroxyvalerate), P(3HB-co-3HV), have been studied. P(3HB) (300 kg mol−1)/P(3HB-co-3HV)–10% 3HV (340 kg mol−1) blends were prepared by casting in a wide range of ...

Poly-3-hydroxybutyrate production byAzotobacter chroococcum
Folia Microbiologica, 2001Thirty-seven soil isolates and mutants of Azotobacter chroococcum tested for poly-3-hydroxybutyrate (PHB) production using Sudan black B staining method were found to be positive. One mutant showed a higher number of PHB-producing cells and maximum number of granules per cell. Using 2% glucose and 15 mmol/L ammonium acetate, PHB production was found to

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).

Journal of Environmental Polymer Degradation, 1994
The microbial degradation of tensile test pieces made of poly(3-hydroxybutyrate) [P(3HB)] or copolymers with 10% [P(3HB-co-10%3HV)] and 20% [P(3HB-co-20%3HV)] 3-hydroxyvaleric acid was studied in small household compost heaps. Degradation was measured through loss of weight (surface erosion) and changes in molecular weight and mechanical strength.

The biodegradation of samples of poly(3-hydroxybutyrate) (P(3HB)), poly(3-hydroxybutyrate-co-10%-3-hydroxyvalerate) (P(3HB-co-10%-3HV)), and poly(3-hydroxybutyrate-co-20%-3-hydroxyvalerate) (P(3HB-co-20%-3HV)) was investigated in situ in natural waters. The degradation was studied by decrease in mass, molecular weight, and tensile strength.
