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.

Lactic acid containing polymers produced in engineered Sinorhizobium meliloti and Pseudomonas putida.

PLoS ONE, 2020
This study demonstrates that novel polymer production can be achieved by introducing pTAM, a broad-host-range plasmid expressing codon-optimized genes encoding Clostridium propionicum propionate CoA transferase (PctCp, Pct532) and a modified Pseudomonas ...

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 ...

Control of D-lactic acid content in P(LA-3HB) copolymer in the yeast Saccharomyces cerevisiae using a synthetic gene expression system

Metabolic Engineering Communications, 2022
The fully biobased polyhydroxyalkanoate (PHA) polymers provide interesting alternatives for petrochemical derived plastic materials. The mechanical properties of some PHAs, including the common poly(3-hydroxybutyrate) (PHB), are limited, but tunable by ...

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 ...

Robust Bioconjugated Antigens Induce Immune Responses Preventing Malaria Infection and its Transmission

Small, Volume 22, Issue 28, 18 May 2026.
Engineered malaria antigens enable in vivo bioconjugation to submicron biopolymer particles in E. coli. Two antigens are co‐tethered at high density and defined stoichiometry. The resulting thermostable particles elicit strong, durable antibody and T‐cell responses, conferring robust protection and blocking mosquito transmission.

Characterization Of A Highly Active Polyhydroxyalkanoate Synthase [PDF]

, 2012
Polyhydroxyalkanoate (PHA) synthase from a locally isolated Chromobacterium sp. USM2 (PhaCCs) exhibited superior polymerizing ability and broad in vivo substrate specificity with preferences for short chain length (SCL) [3-hydroxybutyrate (3HB) and 3 ...
