Polyhydroxyalkanoates (PHAs) are biobased and biodegradable polymers that offer a sustainable alternative to conventional plastics, addressing the escalating concerns over plastic pollution. While their environmental advantages well-documented, efficient degradation of PHAs in natural engineered environments remains critical component lifecycle. This review provides comprehensive overview PHA-degrading bacteria isolated from diverse ecosystems highlights pivotal role PHA depolymerases achieving circularity. Microbial adaptation conditions, such as extreme temperatures, salinity, pH, significantly influences enzymes properties, including stability, activity, substrate specificity enzymes. These adaptations often enhance enzyme, performance, enabling functionality under challenging conditions. Consequently, extremophilic microorganisms invaluable resources for discovering engineering robust industrial applications. underscores urgent need further research improve ecological economic sustainability waste management.

Ischemia-reperfusion (I/R) injury following skin flap transplantation is a critical factor leading to necrosis and transplant failure. Antagonizing inflammatory responses oxidative stress are regarded as crucial targets for mitigating reperfusion enhancing survival. In this study, caffeic acid-vanadium metal polyphenol nanoparticles (CA-V NPs) were prepared the treatment of ischemia reperfusion. This study was conducted using one-step method prepare new types CA-V NPs with uniform sizes stable structures. vitro, exhibited CAT-like SOD-like activities could effectively scavenge ROS, generate oxygen, alleviate stress. H2O2-induced cellular model, reduced ROS levels inhibited apoptosis through XIAP/Caspase-3 pathway. inflammation model induced by LPS combined IFN-γ, reprogrammed macrophage polarization toward M2 phenotype reducing expression chemokines CCL4 CXCL2. addition, animal experiments have shown that can in tissues, inhibit apoptosis, promote angiogenesis, ultimately improve survival rate flaps. provide target strategy I/R injury.

Achieving precise control over the construction of efficient charge transport channels through self-assembly engineering represents a highly effective strategy for synthesis organic supramolecular photocatalysts. Herein, tetragonal zinc meso-5,10,15,20-tetra(4-pyridyl) porphyrin (ZnTPyP) nanorods (T-ZnTPyPs) and hexagonal ZnTPyP nanowires (H-ZnTPyPs) were synthesized by varying assembly temperature. H-ZnTPyPs demonstrated photocatalytic hydrogen production rate (183 mmol/g/h) that was 14.62 times greater than T-ZnTPyP (13 mmol/g/h). This significantly enhanced activity is primarily attributed to distinct well-defined molecular arrangements H-ZnTPyPs, which support continuous linear long-range electron transfer pathways π-π stacking. Conversely, heat manipulation used in T-ZnTPyPs limits participation water molecules crystalline stacking arrangements, leading lattice distortions disrupt interactions impede pathways. research presents novel modulating optimize

Biodegradation is an advanced method for reducing plastic waste in the environment, involving participation of microbial communities with plastic-degrading properties. Our study presents a novel halophilic community isolated from plastic-contaminated region Burgas Lake, Bulgaria. In medium containing 15% sodium chloride, can degrade significant amount polycaprolactone (PCL) as sole carbon source, well plastics polystyrene (PS) and polypropylene (PP), albeit to lesser extent. The showed high hydrophobicity ability form biofilm on PCL beads, esterase activity biodegradation capacity, demonstrated by measuring weight material after cultivation 4 8 weeks. Moreover, scanning electron microscopy (SEM) analysis revealed visible cracks, craters, holes surface polymer particles. metagenomic that Halomonas profundus dominated proportion 95.13%, followed Alloalcanivorax venustensis (2.73%), Chromohalobacter marismortui (0.72%), caseinilytica (0.78%). However, most species were not previously known PCL-degrading. Thus, studying diversity halophile significantly improve our fundamental understanding clarify their potential applications environmental water–plastic remediation.
