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.

Production of Short-Chain-Length/Medium-Chain-Length Polyhydroxyalkanoate (PHA) Copolymer in the Plastid of Arabidopsis thaliana Using an Engineered 3-Ketoacyl-acyl Carrier Protein Synthase III

, 2016
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 ...

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 ...

Increased Production and Molecular Weight of Artificial Polyhydroxyalkanoate Poly(2-hydroxybutyrate) Above the Glass Transition Temperature Threshold

Frontiers in Bioengineering and Biotechnology, 2019
Poly(2-hydroxybutyrate) [P(2HB)] is an artificial polyhydroxyalkanoate (PHA) synthesized using engineered 2-hydroxyalkanoate-polymerizing PHA synthase. In the present study, the effect of temperature on P(2HB) synthesis was investigated.

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.

Alveolar Bone Regeneration: Smart Biomaterials and Physical Stimulation

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 4, April 2026.
ABSTRACT Large‐area bone loss from disease, trauma, or congenital defects requires surgical procedures and bone grafting. Alveolar bone loss from severe periodontal disease and non‐unions often demands immediate grafting. Treating large alveolar bone defects using grafts and substitutes is challenging due to the complex oral environment, infection ...
