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).

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

Relationship of Blood Acetoacetate and 3-Hydroxybutyrate in Diabetes
Diabetes, 1971The ratio of blood ketone bodies 3-hydroxybutyrate to acetoacetate, once thought to be fairly constant, has been shown to vary from 0.6:1 to 4.8:1. In untreated, ketoacidotic patients, it is directly related to the plasma free fatty acid level. Administration of insulin lowers the ratio because the fall of blood 3-hydroxybutyrate occurs earlier and ...

Thermochimica Acta, 2006
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 ...

Polymer, 1994
Abstract The hydrolytic degradation behaviour and some other properties were analysed for blends of microbial poly(3-hydroxybutyrate) [P(3HB)] with microbial poly(3-hydroxybutyrate- co -3-hydroxyvalerate) [P(3HB- co -3HV); 3HV content, 22.3 mol%].

On the lack of formation of l-(+)-3-hydroxybutyrate by liver
Archives of Biochemistry and Biophysics, 1982Abstract The terminal carbon of palmitic acid, traced with 14C, is preferentially incorporated into carbon 4 of hydroxybutyrate formed by hepatocytes and perfused livers from 18- to 19-day-old rats and perfused livers from fasted adult rats. However, 14C from [13-14C]palmitic acid is incorporated into carbon 1 of the hydroxybutyrate to the same ...

Enzymes of l-(+)-3-hydroxybutyrate metabolism in the rat
Archives of Biochemistry and Biophysics, 1980Abstract The three enzymes required for the production and utilization of l -(+)-3-hydroxybutyrate were sought in various tissues of the rat. All tissues examined contained substantial amounts of (No. 1) l -(+)-3-hydroxybutyryl CoA dehydrogenase (EC 1.1.1.35). The specific activity of (No.

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.
