The quest for sustainable solutions to plastic pollution has driven research into plastic-degrading enzymes, offering promising avenues for polymer recycling applications. However, enzymes derived from natural sources often exhibit suboptimal thermostability, hindering their industrial viability. Protein engineering techniques have emerged as a powerful approach to enhance the desired properties of these biocatalysts.

The objective of this study was to examine the residue elimination patterns of seven antibiotics in the eggs of Taihang chickens under free-range conditions and develop suitable withdrawal times (WDTs). A total of 240 healthy Taihang chickens, aged 180 days, were randomly divided into eight groups of 30 birds each. The first seven groups were administered oxytetracycline, chlortetracycline, erythromycin, tylosin, tylvalosin, lincomycin, and tiamulin, respectively, in accordance with the maximum dosages and longest durations of treatment recommended by the Veterinary Pharmacopoeia of the People's Republic of China.

The interest and demand for active food packaging made from all natural materials have increased significantly, driven by the intent to minimize the ecological impact. Green electrospinning from biopolymers with antimicrobial compounds is considered an ideal candidate for constructing ultrathin, excellent performance, and effective antibacterial fibrous films (FFs). Here, a green electrospinning from zein (Z) ethanol-aqueous solution with varied theaflavin (TF) concentrations (0.

The efficient design of novel enzymes has been attainable only by a combination of theoretical approaches and experimental refinement, suggesting inadequate performance of de novo design protocols. Based on the analysis of the evolutionary trajectory of a designed organophosphate hydrolase, this work aimed at developing and validating the improved theoretical models describing the catalytic activity of five enzyme variants (including wild-type as well as theoretically derived and experimentally refined enzymes) performing the hydrolysis of diethyl 7-hydroxycoumarinyl phosphate. The following aspects possibly important for enzyme design were addressed: the level of theory sufficient for a reliable description of enzyme-reactant interactions, the issue of ground state (GS) destabilization versus transition state (TS) stabilization, and the derivation of the proper side chain rotamers of amino acid residues.

Article Synopsis
  • Environmental residues of the fungicide difenoconazole (DFZ) can harm mammals, but its effects on cultured carp are poorly understood, prompting this study to explore the impact on carp liver and underlying mechanisms.
  • The research found that DFZ causes significant liver damage, including structural issues and mitochondrial dysfunction, by promoting calcium transfer and increasing reactive oxygen species (ROS), leading to cell death.
  • Treatment with 2-APB showed potential in mitigating DFZ-induced damage by restoring mitochondrial function and metabolic balance, emphasizing the need for understanding the consequences of agricultural chemicals on aquatic ecosystems.
