over the years, the use of plastics has complicated the problem of disposal of solid wastes. one strategy to reduce plastic waste is the use of biodegradable plastics. a group of these plastics are polyhydroxyalkanoates (phas). to date more than 250 different microorganisms are known to synthesize and accumulate pha. most pseu-domonas strains are able to accumulate mcl-pha. in previous studies,...

Abstract Polyhydroxyalkanoates (PHA) produced by many bacteria have been investigated by microbiologists, molecular biologists, biochemists, chemical engineers, chemists, polymer experts, and medical researchers over the past many years. Applications of PHA as bioplastics, fine chemicals, implant biomaterials, medicines, and biofuels have been developed. Companies have been established or invol...

We examine the effectiveness of asset markets when the final outcome upon which the asset payout is based maybe affected by the unobservable actions of the traders. Players participate in a minimum effort coordination game preceeded by an information market where the asset payoffs are determined by the observed minimum effort level in the subsequent game. We examine both the informativeness of ...

Polyhydroxyalkanoates (PHA) are diverse polyesters synthesized by a variety of bacteria as intracellular carbon and energy storage compounds. As bio-renewable and biodegradable materials with diverse properties, PHA have drawn industrial attentions for their potential applications in many fields. This review focuses on recent strain developments for PHA production via cofactor engineering and m...

The thermophile Cupriavidus sp. strain S-6 accumulated polyhydroxybutyrate (PHB) from glucose at 50°C. A 9.0-kbp EcoRI fragment cloned from the genomic DNA of Cupriavidus sp. S-6 enabled Escherichia coli XL1-Blue to synthesize PHB at 45°C. Nucleotide sequence analysis showed a pha locus in the clone. The thermophilic polyhydroxyalkanoate (PHA) synthase (PhaC(Csp)) shared 81% identity with mesop...

Although polyhydroxyalkanoate (PHA) accumulation and mobilization are one of the most general mechanisms for haloarchaea to adapt to the hypersaline environments with changeable carbon sources, the PHA mobilization pathways are still not clear for any haloarchaea. In this study, the functions of five putative (R)-specific enoyl-CoA hydratases (R-ECHs) in Haloferax mediterranei, named PhaJ1 to P...

Polyhydroxyalkanoate (PHA) production was achieved using tomato cannery waste coupled with a mixed microbial culture during wastewater treatment. The two-stage PHA production process comprised a sequencing batch reactor (SBR), operating under a periodic feast-famine regime, to accomplish simultaneously wastewater treatment and selection of PHA-accumulating microbes, followed by a batch reactor ...

BACKGROUND The number of elderly people on dialysis is increasing rapidly. Fluid overload and malnutrition status are serious problems in elderly dialysis patients. We aimed to compare the hydration and nutritional status through bioimpedance analysis (BIA) between young and elderly hemodialysis (HD) patients and to analyze risk factors related to fluid overload and malnutrition status in these...

Short-chain-length/medium-chain-length (SCL/MCL) polyhydroxyalkanoate (PHA) was produced in the plastids of Arabidopsis thaliana. Phe87Thr (F87T) mutated 3-ketoacyl-acyl carrier protein (ACP) synthase III (FabH) from Escherichia coli , and Ser325Thr/Gln481Lys (ST/QK) mutated polyhydroxyalkanoate (PHA) synthase (PhaC1) from Pseudomonas sp. 61-3, along with the beta-ketothiolase (PhaA) and acetoa...
