Effects of alkylene spacer length of 2-pyrone-4,6-dicarboxylic acid polyesters on biodegradability and metal adhesive properties

NPG Asia Materials
2-Pyrone-4,6-dicarboxylic acid (PDC) is a lignin-derived biometabolic intermediate that can be produced on a large scale by using transforming bacteria and can be directly polymerized by polycondensation with diols to produce biomass polyesters.

Deep Learning‐Driven Discovery and Engineering of an Efficient PETase for Depolymerization and Detoxification of PET Microplastics Under Physiological Conditions

Advanced Science, EarlyView.
A deep learning–driven pipeline mining 246 million protein sequences uncovers AhPETase, an evolutionarily distinct PET hydrolase. Engineered variant AhPETaseM1 degrades post‐consumer PET microplastics under physiological conditions and reverses microplasticinduced cytotoxicity in human lung and colon cells, establishing enzymatic microplastic ...
