Poly(hydroxyalkanoate)s from Waste Biomass: A Combined Chemical–Biological Approach

Abstract

The synthesis of polyhydroxyalkanoates (PHAs) utilizing methane and alkenoates derived from recycled PHAs is reported. Medium‐chain length (C 6 – C 9 ) and short‐chain length (C 4 – C 5 ) polyhydroxyalkanoates were catalytically pyrolyzed to generate a range of 2‐alkenoates. The microbial copolymerization of the recovered alkenoates with methane in the presence of methanotrophic bacteria generated poly(3‐hydroxybutyrate) homopolymers from even‐numbered alkenoates and, significantly, poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) copolymers with tunable compositions from odd‐numbered alkenoates.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Methanotrophic bacteria that produce PHAs can be found at wastewater treatment plants, which are often geographically close to sources of waste methane.

  • Catalytic pyrolysis using Mg(OH)2 as the catalyst was used to recycle a variety of short- and medium-chain length PHAs and proved the utility of the recovered monomers as feedstocks for microbial synthesis of PHAs.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
