Second‐Generation Polyhydroxybutyrate Production From Pretreated Corn Lignocellulosic Fraction as a Strategy to Repurpose by Products From the Corn‐Processing Chain

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Lignocellulosic residues are non‐cost, non‐edible, renewable feedstocks that can be used in polyhydroxybutyrate (PHB) production. PHB is a bioplastic synthetized by microorganisms, formed intracellularly under stressful growth conditions; however, its production costs are high, representing the major drawback for fossil‐based plastics ...

Valorization of Textile Waste: Enzymatic Upcycling of Terephthalic Acid Toward a Sustainable PET Value Chain

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT The rapid expansion of the global textile industry, driven by the fast‐fashion paradigm, which is characterized by low‐cost, short‐lived garments made from inexpensive synthetic fibers, has intensified environmental pressures through increased waste generation, resource depletion, microplastic pollution, and greenhouse gas emissions ...

Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms

BMEMat, EarlyView.
This review highlights critical “translational gaps” in understanding micro‐ and nanoplastics impacts on gastrointestinal diseases, bridging exposure, detecting, and mechanistic toxicology. Abstract Micro‐ and nanoplastics (MNPs) have become pervasive environmental contaminants with increasing evidence linking them to adverse health outcomes.

Mimicking the Fungal Decay Strategy for Promoting the Bacterial Production of Polyhydroxyalkanoate from Kraft Lignin

Fermentation, 2023
Producing polyhydroxyalkanoate (PHA) from lignin through biological conversion has great further potential, but is held by its high heterogeneous characteristic toxicity of the depolymerized products, and low bioconversion of the depolymerized products ...

Improving the Mechanical Properties of Biodegradable Polyhydroxyalkanoates via PHA–PHA Block‐Copolymer Synthesis

Chemistry – A European Journal, EarlyView.
Covalent linkage of a highly crystalline PHBV with a ductile P3HB4HB is shown to produce block copolymers with markedly enhanced extensibility and toughness, outperforming equivalent blends. The results demonstrate that polymer architecture, not composition alone, governs mechanical response, offering a route to biodegradable materials that combine ...
