Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Polyhydroxyalkanoate (PHA) Synthesis by Class IV PHA Synthases EmployingRalstonia eutrophaPHB⁻4 as Host Strain [PDF]

Bioscience, Biotechnology, and Biochemistry, 2011
Class IV polyhydroxyalkanoate (PHA) synthase from Bacillus cereus YB-4 (PhaRC(YB4)) or B. megaterium NBRC15308(T) (PhaRC(Bm)) was expressed in Ralstonia eutropha PHB(-)4 to compare the ability to produce PHA and the substrate specificity of PhaRCs. PhaRC(YB4) produced significant amounts of PHA and had broader substrate specificity than PhaRC(Bm).

Phosphate Limitation Modulates Vibrio Cholerae Outer Membrane Vesicle Formation, Composition and Toxicity

Journal of Extracellular Biology, Volume 5, Issue 5, May 2026.
ABSTRACT Vibrio cholerae inhabits phosphorus‐poor aquatic environments and host intestine, where it expresses genes regulated by the PhoB/PhoR two‐component system in response to inorganic phosphate (Pi) limitation. Like other Gram‐negative bacteria, V.

Polyhydroxyalkanoates as Sustainable Agricultural Plastics: Processing Strategies, Performance, and Environmental Perspectives

Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
This review highlights polyhydroxyalkanoates (PHAs) as biodegradable materials for agricultural plastics. It outlines how composition, processing, and formulation strategies shape material properties and end‐of‐life behavior. Applications in films and foams are discussed alongside current limitations in cost and scalability, emphasizing emerging ...

Skeletal muscle mitochondrial marker responses to a single bout and 6 weeks of high load versus high volume resistance training in previously trained men

Experimental Physiology, Volume 111, Issue 5, Page 2564-2574, 1 May 2026.
Abstract The effects of high‐load (HL) versus high‐volume (HV) resistance training (RT) on various molecular outcomes are similar. However, mitochondrial responses remain understudied. Therefore, the purpose of this study was to interrogate mitochondrial mRNA and protein responses to acute and chronic HL versus HV RT.

Inactivation of type I polyhydroxyalkanoate synthase in Aeromonas hydrophila resulted in discovery of another potential PHA synthase

Journal of Industrial Microbiology & Biotechnology, 2006
Aeromonas hydrophila CGMCC 0911 possessing type I polyhydroxyalkanoate (PHA) synthase (PhaC) produced only PHBHHx from lauric acid but not from glucose. Medium-chain-length (mcl) PHA was produced from lauric acid or glucose only when PhaC of A. hydrophila was inactivated, indicating the existence of another PHA synthase in the wild type.

In vivo immobilization of an organophosphorus hydrolyzing enzyme on bacterial polyhydroxyalkanoate nano-granules

Microbial Cell Factories, 2019
Background Polyhydroxyalkanoate (PHA) are nano-granules naturally produced by bacteria. Two types of proteins, PHA synthase (PhaC) and phasins (PhaPs), are attached to the PHA surface by covalent and hydrophobic interactions.

Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

Advanced Functional Materials, Volume 36, Issue 33, 23 April 2026.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles

Production of functionalized polyhydroxyalkanoates by genetically modified Methylobacterium extorquens strains

Microbial Cell Factories, 2010
Background Methylotrophic (methanol-utilizing) bacteria offer great potential as cell factories in the production of numerous products from biomass-derived methanol. Bio-methanol is essentially a non-food substrate, an advantage over sugar-utilizing cell
