Summary: The study focuses on coating cotton yarn with poly(vinyl alcohol) to provide temporary tensile strength. Crosslinking processes using UV-C radiation and glutaraldehyde were investigated to increase the strength of the coating layer. Results showed that glutaraldehyde crosslinking reduced polymer crystallinity, affecting yarn performance, while PVA coating and UV-C radiation crosslinking increased tensile strength by up to 56% due to the creation of a new crystalline network. UV-C radiation offers promise by eliminating the use of chemical reagents and toxic waste generation.

Summary: High elongation and transparent PVA/MMT nanocomposites with high MMT content are prepared by evaporation-induced assembly with micro-crosslinking, inhibiting the formation of rod-shaped arrays and resulting in a more ordered layered microstructure. This approach provides a potential compromise between high strength and excellent elongation at the same MMT content, while also improving the transparency of the eventual films.

Summary: This study investigates the influence of glucose addition on the structure and mechanical properties of alginate solutions and calcium-alginate hydrogels. It is found that the addition of glucose can increase the gel strength and elasticity. The nanostructure of the gel remains unchanged at low glucose concentrations but undergoes changes at high concentrations. This has relevance for the design of alginate hydrogels for food and pharmaceutical applications.

Summary: In this study, the properties of hydrogels produced from fish-derived collagen cross-linked with varying concentrations of glutaraldehyde (GA) were evaluated. The results showed that the water absorbency, swelling, porosity, pore size, and water retention of the hydrogels were influenced by the level of cross-linking. Additionally, the active peptides from salmon gelatin and tilapia gelatin exhibited a high binding affinity to the alpha-glucosidase enzyme, indicating their potential as antidiabetic agents and alternatives to mammalian-derived gelatin.

Summary: This study aims to fabricate a collagen-like extracellular matrix (ECM) analog using green electrospinning methods for tissue culture and disease research. The results demonstrate that by optimizing crosslinking and using the green electrospinning solvent acetic acid, collagen-like mesh structures with nano- and micro-scale cues and continuous fibrous architecture can be produced, and they exhibit stability in both dry and wet conditions. These collagen-like mesh structures support the in vitro expansion of cells and the production of mineralized matrix.

Summary: Bacteria generate and release extracellular reactive oxygen species (eROS), which significantly contribute to the natural ROS pool and play a crucial role in metabolic interactions of bacteria with their environment. Understanding the behavior of eROS-generating bacteria and its environmental implications is of great importance in the cycling of biogeochemical elements, transformation of organic matter, and regulation of antibiotic resistance genes.

Summary: Plastics and microplastics are widely present and accumulating in the environment, leading to increasing public attention. In addition to packaging plastics, materials from industries such as electronics, space and aviation are also accumulating, but receiving less attention. The production of degradable and biodegradable plastics is seen as a way to reduce environmental impacts, but enhancing the non-degradability of functional polymers is also a feasible option. Microbial colonization and deterioration pose significant challenges to these materials.

Summary: This study evaluated the keratinolytic activity of 37 strains of Trichophyton ajelloi and found that pigmented strains isolated from loamy soil were more efficient in degrading native feather keratin, while non-pigmented strains isolated from chernozem showed better abilities. The keratinolytic activity increased over time, as evidenced by the increase in extracellular keratinase activity and release of soluble proteins and peptides. Protease activity peaked in the first 7 days and again on day 28 of culture. The release of ammonium and sulfate ions, associated with an increase in pH, reached its maximum on day 21. Three pigment-producing strains were among the most active in releasing large amounts of ammonium and sulfate ions. The biodegradation of feather waste by Trichophyton ajelloi strains can be used to produce fertilizers suitable for plants with high sulfur requirements.

Summary: The incomplete recycle of residual mulch film (RMF) in recent years has led to an increase in plastic fragments in soil, posing a serious threat to the soil ecological environment. In this study, seven potential plastic-degrading microorganisms were screened and identified from film-mulched vegetable fields. The degradation ability experiments showed that both single strains and mixed strains demonstrated varying levels of degradation of RMF.

Summary: This study investigated the degradation of heat-treated wood by brown rot fungi and found that the decay increased the hygroscopicity of wood in the decaying state. Furthermore, it was observed that heat-treated samples were more susceptible to fungal decay compared to untreated samples, which may be related to the increase in moisture content.

Summary: This study investigated the phenomenon of Centimetric circular areas Uncolonized by Microbial Biofilms (CUMBs) on natural and heritage stone surfaces. The analysis revealed a compatibility in distribution and size between CUMBs and lichen thalli, suggesting a lichen origin for some CUMBs. Microscopic analysis also showed similar modifications in marble layers beneath CUMBs and lichens, indicating a possible alteration of stone properties by lichens.
