Conventional plastic can lead to endless pollution as it took millions of years be disposed of, hence an alternative using biodegradable replacing regular everyday has highly participated. Polyhydroxyalkanoates (PHA) have the characteristics a however, exhibits low heat distortion temperature. The objective this research is investigate effect nanosilver additions on thermal properties PHA compo...

Polyhydroxyalkanoate (PHA), produced by mixed microbial cultures (MMCs), is a biodegradable biopolyester that alleviates the global plastic crisis in nearest future. Even PHA has become research hotspot, reviews on composition determining thermodynamic and processing properties of products are rare. The primary focus evaluation relies factors affecting monomer MMC-PHA production. Besides, since...

Because of their lower environmental impact, biodegradable polymers such as polyhydroxyalkanoates (PHAs) produced within cultured bacteria represent promising alternatives to petroleum-based plastics. PHA production in flasks yielded optimal results with a carbon-to-nitrogen ratio 22. The 5-L scale experimental revealed that when glucose was used the carbon source, Cupriavidus necator could pro...

A novel strategy for micropatterning proteins on the surface of polyhydroxyalkanoate (PHA) biopolymer by microcontact printing (microCP) is described. The substrate binding domain (SBD) of the Pseudomonas stutzeri PHA depolymerase was used as a fusion partner for specifically immobilizing proteins on PHA substrate. Enhanced green fluorescent protein (EGFP) and red fluorescent protein (RFP) fuse...
