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

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%].

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.

Carboxylate-Induced Degradation of Poly(3-hydroxybutyrate)s
Biomacromolecules, 2007This communication shows that thermal degradation of poly(3-hydroxybutyrate)s (PHBs) is induced by carboxylate groups via a newly proposed E1cB mechanism. In PHBs with end groups in the form of carboxylic acid salts with Na+, K+, and Bu4N+ counterions, the proposed mechanism explains the dependence of thermal stability on the size of the counterion ...
