Metagenomic characterization of Candidatatus Defluviicoccus tetraformis TFO71, a tetrad-forming organism, predominant in an anaerobic-aerobic membrane bioreactor with deteriorated biological phosphorus removal
… to the synthesis and degradation of glycogen and polyhydroxyalkanoate (PHA), which function as energy and carbon storage compounds. Both TFO71 and Candidatus Accumulibacter phosphatis (CAP) UW-1, a representative polyphosphate-accumulating organism (PAO), have PHA metabolism-related genes with …

Extracting transcriptional regulatory information from DNA microarray expression data
… commercially interesting, biodegradable polymer polyhydroxyalkanoate (PHA). We have created DNA microarrays with [approximately]97% of the Synechocystis genome represented in duplicate to monitor the cellular transcriptional profile. These arrays are used in time-series experiments of differing …

Mechanistic investigation of polyhydroxybutyrate (PHB) synthases and elucidation of PHB biosynthesis and degradation process in Wautersia eutropha H16
Polyhydroxyalkanoate (PHA) synthase from various bacterial organisms is able to catalyze the polymerization of (R)-hydroxyalkanoate-CoAs into high molecular weight PHAs under nutrient- limited conditions in the presence of a carbon source. PHA synthases are representative of enzymes involved in …

Advancing wastewater valorization using anaerobic membrane bioreactors with bioaugmentation and ion-exchange, and bio-plastic production
… namely enhanced methane recovery in a novel two-phase anaerobic membrane bioreactor (AnMBR) process incorporating bioaugmentation and ion-exchange resins, as well as bio-polymer recovery via mixed microbial culture (MMC) polyhydroxyalkanoate (PHA) production. The first study presented in this …

Ruminal Degradation of Polyhydroxyalkanoate and Poly(butylene succinate-co-adipate)
… plastic impaction in domestic ruminants. Using polyhydroxyalkanoate (PHA) and poly(butylene succinate-co-adipate) (PBSA) biodegradable materials for feed storage products such as bale netting could reduce the incidences and effects of polyethylene-based plastic impaction in ruminants. The …

Effects of Fused Filament Fabrication Process Variables on Microstructural Alignment and Intra-layer Properties in PLLA
… a multi-material transition from dual PLLA and polyhydroxyalkanoate (PHA)/PLLA blend layers to a single PLLA layer, orientating the interface towards the printing direction. This transition was imaged using polarised light microscopy, and had a total thickness of ≈ 125 μm. The results confirmed …
