Polyhydroxyalkanoates (PHA) producers have been found in a variety of ecological niche’s that are naturally or unintentionally exposed to high organic matter growth limiting substances such as dairy wastes, hydrocarbon contaminated sites, pulp and paper mill agricultural activated sludges treatment plants, rhizosphere, industrial effluents. Few them also create extracellular byproducts rhamnoli...

In the context of circular economy and sustainable production materials, this project investigated feasibility producing polyhydroxyalkanoates (PHA) from microalgae sludge used in treatment municipal wastewater. The overall process was studied looking at main steps: production, fermentation biomass, characterization PHAs. It possible to obtain blends hydroxybutyrate-hydroxyvalerate copolymers w...

Polyhydroxyalkanoates (PHAs) are a group of microbial biodegradable polymers having potential to replace synthetic plastics. Several factors are known to influence PHA biosynthesis e.g., bacterial strain used, carbon and nitrogen sources provided, culture conditions, etc. These factors interact with each other during productionand their interaction can be assessed using statistical methods. In ...

Polyhydroxyalkanoates (PHA) are natural polyesters stored by a wide range of bacteria as carbon source reserve. Due to its chemical characteristics and biodegradability PHA can be used in chemical, medical and pharmaceutical industry for many human purposes. Over the past years, few Burkholderia species have become known for production of PHA. Aside from that, these bacteria seem to be interest...

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...

Medium-chain-length polyhydroxyalkanoates (PHAs) are polyesters having properties of biodegradable thermoplastics and elastomers that are naturally produced by a variety of pseudomonads. Saccharomyces cerevisiae was transformed with the Pseudomonas aeruginosa PHAC1 synthase modified for peroxisome targeting by the addition of the carboxyl 34 amino acids from the Brassica napus isocitrate lyase....

Polyhydroxyalkanoates (PHA) are efficient, renewable and environment friendly polymeric esters. These polymers are synthesized by a variety of microbes under stress conditions. This study was carried out to check the suitability of waste frying oil in comparison to other oils for economical bioplastic production. Six bacterial strains were isolated and identified as Bacillus cereus (KF270349), ...

The regulation of medium-chain-length polyhydroxyalkanoates (mcl-PHA) metabolism in Pseudomonas putida GPo1 was studied by analysis of enzymes bound to PHA granules and enzymes involved in fatty acid oxidation. N-terminal sequencing of granule-bound enzymes revealed the presence of PHA polymerase (PhaC) and PHA depolymerase (PhaZ) and an acyl-CoA synthetase (ACS1), which recently was found to b...

The use of polyhydroxyalkanoates (PHA) as slow-release electron donors for environmental remediation represents a novel and appealing application that is attracting considerable attention in the scientific community. In this context, here, fermentation pattern different types PHA-based materials has been investigated batch continuous-flow experiments. Along with commercially available materials...
