Polyhydroxyalkanoates: an overview

Bioresource Technology, 2003
Polyhydroxyalkanoates have gained major importance due to their structural diversity and close analogy to plastics. These are gaining more and more importance world over. Different sources (natural isolates, recombinant bacteria, plants) and other methods are being investigated to exert more control over the quality, quantity and economics of poly(3 ...

Polyhydroxyalkanoates

2020
Human dependence on number of chemicals or chemical derivatives has increased alarmingly. Among the commodity chemicals, plastics are becoming independent for our modern lifestyle, as the usage of plastics is increasing worryingly. However, these synthetic plastics are extremely persistent in nature and accumulate in the environment, thereby leading to

Bacterial polyhydroxyalkanoates

Biotechnology and Bioengineering, 1996
Polyhydroxyalkanoates (PHAs) are polyesters of hydroxyalkanoates (HAs) synthesized by numerous bacteria as intracellular carbon and energy storage compounds and accumulated as granules in the cytoplasm of cells. More than 80 HAs have been detected as constituents of PHAs, which allows these thermoplastic materials to have various mechanical properties ...

Polyhydroxyalkanoates based copolymers

International Journal of Biological Macromolecules, 2019
Polyhydroxyalkanoates (PHAs) belong to a family of natural polyesters and are produced under unbalanced growth conditions as intracellular carbon and energy reserves by a wide variety of microorganisms. Being biodegradable, biocompatible and environmental friendly thermoplastics, the PHAs are considered as future polymers to replace petrochemicals ...

Hydrolytic degradation of blends of polyhydroxyalkanoates and functionalized polyhydroxyalkanoates

Polymer Degradation and Stability, 2004
Abstract The hydrolytic degradation of poly(3-hydroxyalkanoates), PHA, blends with low and high molecular weight additives was examined. The PHA films were characterised by Differential Scanning Calorimetry, DSC, and Atomic Force Microscopy, AFM. The DSC and AFM results revealed that hydrolyzable PLA and hydrophilic PEG, selected as additives which ...

Microbial Degradation of Polyhydroxyalkanoates

Annual Review of Microbiology, 2002
▪ Abstract  Polyesters such as poly(3-hydroxybutyrate) (PHB) or other polyhydroxyalkanoates (PHA) have attracted commercial and academic interest as new biodegradable materials. The ability to degrade PHA is widely distributed among bacteria and fungi and depends on the secretion of specific extracellular PHA depolymerases (e-PHA depolymerases), which ...
