Summary: Mealworms are capable of degrading polystyrene, but the molecular weight of polystyrene affects the degradation process and the response of mealworms. By feeding mealworms with polystyrene microplastics of different molecular weights, the study investigated the degradation of polystyrene, gut microbiome, and metabolome. The findings reveal that mealworms can degrade polystyrene through broad or limited depolymerization, and the degradation process leads to changes in their gut microbiome and metabolome.

Summary: The involvement of wood decay fungi in the degradation of low-density polyethylene (LDPE) has been studied and it has been found that these fungi play a significant role in LDPE degradation. The best performing fungi in LDPE degradation were identified, with Phlebiopsis flavidoalba showing the highest weight reduction and the lowest contact angle. Interestingly, all isolates exhibited higher LDPE degradation in the absence of wood compared to the presence of wood.

Summary: The involvement of wood decay fungi in the degradation of low-density polyethylene (LDPE) has been studied. 50 fungal samples isolated from decaying hardwoods were assessed for their wood degradation ability and depolymerization enzymatic activities, and 22 isolates were found to have both abilities. Among them, Phlebiopsis flavidoalba showed the highest percentage of weight reduction and the lowest contact angle in the absence of wood. A proposed mechanism for LDPE degradation by P. flavidoalba was also suggested.

Summary: Low molecular weight lignin (LMW-Lignin) has high phenolic hydroxyl content and excellent bioactivity, making it highly promising for energy storage and antibacterial materials. However, conventional lignin sources have large molecular weights and inactive functional groups, limiting their potential applications. This study found that methanol inhibits the recondensation of lignin fragments in a hydrothermal alkaline system. Optimized conditions resulted in the production of low molecular weight lignin.

Summary: Analysis of cis-diol compounds is crucial due to their important roles in various fields. Researchers have developed a matrix-assisted laser desorption/ionisation mass spectrometry (MALDI-MS) method to effectively analyse cis-diol compounds. This method utilizes a unique reactive matrix (BMQI) for in situ derivatization of cis-diol compounds, resulting in improved speed, reproducibility, and signal intensity, as well as reduced background interference. Additionally, the method has been successfully applied to the rapid screening and identification of sugar alcohols in different sugar-free foods.

Summary: Sulfonylurea herbicides are widely used in modern agriculture but have adverse effects on ecosystems and human health. Effective techniques, including biodegradation, have been explored to remove sulfonylurea residues from the environment. Microbial strains such as Talaromyces flavus LZM1 and Bacillus subtilis LXL-7 show high degradation capabilities. The molecular mechanisms of microbial degradation are not well studied, but enzymes such as hydrolase, oxidase, dehydrogenase, and esterase play important roles. This article provides a comprehensive discussion on the strains, pathways, and mechanisms of sulfonylurea biodegradation, as well as their toxic effects on aquatic and terrestrial animals, aiming to offer new ideas for remediation of sulfonylurea herbicide-polluted soil and sediments.

Summary: The functions of materials are highly dependent on their ordered molecular arrangements. Researchers have discovered a low molecular weight spiropyran that exhibits photochromism and powerful adhesion in a disordered solid state. The adhesion strength can be regulated by light, and the specific color state corresponds to different levels of adhesion strength. The isomer ratio and molecular packing density of the spiropyran are the key factors determining the adhesion ability. This discovery provides a new strategy for developing functional materials using low molecular weight compounds.

Summary: Mycotoxins, the most researched biological toxins, can contaminate food and feed, resulting in severe health implications for humans and animals. The use of microbial enzymes in biotransformation offers a promising method to mitigate mycotoxin contamination. Specific enzymes have advantages over whole microbial cells, including higher degradation rates and substrate specificity. However, there is a need to identify and utilize more novel microbial enzymes to effectively reduce mycotoxins.

Summary: This study explores the curing characteristics of low molecular weight melamine-urea-formaldehyde (MUF) resin within impregnated wood during the drying process. By analyzing the effects of resin solution concentration and wood on the curing process, the optimum curing temperature and kinetic parameters of the resin were obtained. The study found that moisture and wood hinder the curing and cross-linking of the resin, leading to an increase in curing time.
