Polyhydroxyalkanoates, challenges and opportunities
Current Opinion in Biotechnology, 2014Microbial polyhydroxyalkanoates (PHA) have been developed as biodegradable plastics for the past many years. However, PHA still have only a very limited market. Because of the availability of large amount of shale gas, petroleum will not raise dramatically in price, this situation makes PHA less competitive compared with low cost petroleum based ...

Biodegradation of polyhydroxyalkanoic acids
Applied Microbiology and Biotechnology, 1996Stimulated by the commercial availability of bacteriologically produced polyesters such as poly[(R)-3-hydroxybutyric acid], and encouraged by the discovery of new constituents of polyhydroxyalkanoic acids (PHA), a considerable body of knowledge on the metabolism of PHA in microorganisms has accumulated.

Polyhydroxyalkanoate-based Multiphase Materials
2014This chapter deals with polyhydroxyalkanoate (PHA)-based multiphase materials, their preparation, properties, and possible applications. After a brief introduction to the different PHAs and their main physical properties, their limitations and weaknesses are exposed and possible solutions arising from PHA-based multiphase systems are introduced.

Polyhydroxyalkanoates in Packaging
2019Synthetic plastics have been very well recognized for the packaging industry. An evident inclination towards development of biodegradable Bioplastics based on biological material and, particularly for bulk packaging applications has been perceived as a strategy to overcome the dependency of packaging sector on fossil fuels and diminish the biospheric ...

Polysaccharide und Polyhydroxyalkanoate
2013Polymere nehmen eine zentrale Rolle im Kohlenstoffkreislauf der Natur ein und werden in ungeheuer grosen Mengen synthetisiert. Es wird geschatzt, dass Pflanzen jahrlich z. B. ca. 50 bis 100 Gigatonnen Cellulose und in etwa die gleiche Menge Lignin produzieren. Bezogen auf die Masse ist dies ein Vielfaches der jahrlichen Erdolforderung (ca.
