The first methanotrophic syntheses of polyhydroxyalkanoates (PHAs) that contain repeating units beyond 3-hydroxybutyrate and 3-hydroxyvalerate are reported. New PHAs synthesized by methanotrophs include poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P(3HB-co-4HB)), poly(3-hydroxybutyrate-co-5-hydroxyvalerate-co-3-hydroxyvalerate) (P(3HB-co-5HV-co-3HV)), poly(3-hydroxybutyrate-co-6-hydroxyhexanoate-co-4-hydroxybutyrate) (P(3HB-co-6HHx-co-4HB)). This was achieved from a pure culture...
Thermoplastic blends are applied for three-dimensional (3D) printing to obtain improved functionality. While thermal, chemical, and mechanical properties of 3D-printed typically examined, biodegradability the plastics has rarely been focus research. In this study, we evaluated biodegradation behavior prototypes fabricated from various blends, including biodegradable polylactic acid (PLA), poly(3-hydroxybutyrate) (PHB), non-biodegradable high-density polyethylene (HDPE), polypropylene (PP)....
The boric acid-crosslinked polyvinyl alcohol coating on paper remarkably improves barrier properties and mechanical robustness without compromising biodegradability biocompatibility, a green advance in sustainable packaging.
Sepia melanin, a biopigment extracted from the ink sac of cuttlefish, is relevant to sustainable organic electronics. In this work, we flexographically print films an melanin including shellac as bio-sourced binder on silver electrode-patterned paper. We examine electrical response in high humidity and ambient conditions (here electronic conductivity 10−4 S/cm). Additionally, study biodegradation printed their individual constituents based mineralization into CO2 under composting conditions....
The coupled aerobic–anoxic nitrous decomposition operation is a new process for wastewater treatment that removes nitrogen from and recovers energy the in three steps: (1) NH4+ oxidation to NO2–, (2) NO2– reduction N2O, (3) N2O conversion N2 with production. Here, we demonstrate type II methanotrophic enrichments can mediate step two by coupling of poly(3-hydroxybutyrate) (P3HB) reduction. Enrichments grown were subject alternating 48-h aerobic anoxic periods, which CH4 added together...
Long-term operation of wastewater-fed, microbial fuel cells (MFCs) with cathodes made activated carbon and stainless steel (SS) current collectors can result in decreased performance due to cathode fouling.
Abstract The synthesis of polyhydroxyalkanoates (PHAs) utilizing methane and alkenoates derived from recycled PHAs is reported. Medium‐chain length (C 6 – C 9 ) short‐chain 4 5 were catalytically pyrolyzed to generate a range 2‐alkenoates. microbial copolymerization the recovered with in presence methanotrophic bacteria generated poly(3‐hydroxybutyrate) homopolymers even‐numbered and, significantly, poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) copolymers tunable compositions odd‐numbered alkenoates.
Methanotrophs are crucial in keeping environmental CH
Aquatic environments account for half of global CH4 emissions, with freshwater wetlands being the most significant contributors. These fluxes can be partially offset by aerobic oxidation driven methanotrophs. Additionally, some methanotrophs convert into polyhydroxyalkanoate (PHA), an energy storage molecule as well a promising bioplastic polymer. In this study, we investigate how PHA-accumulating methanotrophic communities enriched from were shaped varying resource availability (i.e., C and...
ABSTRACT Methanotrophs are crucial in keeping environmental CH 4 emissions check. However, how different groups of methanotrophs contribute to this important role settings remain ambiguous. Here, a simplified laboratory setting well-mixed batch reactors fed continuous flow -containing gas, methanotrophic microbiomes were enriched from paddy soils under six incubation conditions prepared as combinations two mixing ratios (0.5% and 10% v/v) three supplemented Cu 2+ concentrations (0, 2, 10...
