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.

Dilemma in Carotenoids Versus Polyhydroxyalkanoates (PHAs) Synthesis Using Haloarchaea as Cell Factories

Chemistry – A European Journal, EarlyView.
Production of PHAs by haloarchaea: the production of carotenoids and PHAs is concomitant, and consequently, various metabolic pathways compete for the carbon source. This results in a loss of PHA production efficiency. Efficient control of carbon source utilization (favoring certain metabolic pathways at the expense of others) is the key to the ...

A lumped modelling framework for the epoxidation of vegetable oils and fatty acid methyl esters

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Epoxidized vegetable oils and fatty acid methyl esters are promising bio‐based alternatives to phthalates for plasticizer applications. Their synthesis typically involves the reaction of unsaturated double bonds with peracetic acid in a biphasic liquid–liquid system, where the simultaneous occurrence of reaction and phase partitioning makes ...
