Summary: This study explored the adsorption and degradation capability of four Lactobacillus strains on ZEN, finding that they exhibited good adsorption and degradation effects on ZEN in a certain salt solution. Furthermore, heat-treated Lactobacillus strains showed better reduction of ZEN, making them potential natural adsorbents for removing ZEN from food products and feedstuffs.

Summary: In this study, the newly reported NiB monolayer with topological metal properties exhibited excellent catalytic activity and high selectivity for NO-to-NH3 conversion. The unique building blocks of Ni-B triangles and tetragons facilitated NO adsorption and activation. The optimal reduction pathway for NH3 synthesis was identified, and the hydrogen evolution reaction (HER) and partial reduction channel were found to be less competitive. These findings expand the potential application of two-dimensional topological materials in electrocatalysis.

Summary: This paper provides a comprehensive analysis of the physical properties of Al-doped ZnO and H-Al co-doped materials, showing that the H-Al co-doped material exhibits better physical properties compared to Al-doped ZnO, such as smaller lattice distortion, higher carrier mobility, and increased conductivity. In addition, the H-Al co-doped material has higher transmittance in the visible region.

Summary: The oral cavity is a highly concentrated environment of microorganisms on the human body, and maintaining its balance is essential for oral health. Studies have shown that the probiotic strain Bifidobacterium animalis subsp. lactis (B. lactis) HN019 can reduce pathogenicity and immune inflammation in the oral cavity, making it a potential treatment for periodontitis and peri-implant mucositis.

Summary: We investigate the performance of caching schemes based on two coding techniques. A heterogeneous network is assumed, with cache-aided relays connected to a primary node through a backhaul link, while users have no direct connection to the primary node. The first scheme fills the cache with encoded content, while the second scheme encodes the content during delivery. We compare the schemes by analyzing the average transmission load when users request content from the network. We derive an approximation for the average load expression, enabling a quick evaluation of each scheme's network behavior. Additionally, we consider a capacity constraint on the backhaul link and derive the expression for the outage probability, indicating the likelihood of the system failing to serve all user demands. Finally, we explore scaling the analysis of a two-relay scenario to study networks with varying numbers of relays.

Summary: A comparative controlled study was conducted to evaluate the performance of Saccharomyces cerevisiae var. boulardii as brewer's yeast for potential probiotic beer production. Changes in malt concentration and temperature profile were made to improve the yeast metabolism, with survival in beer indicating potential probiotic properties. Further research is needed to fully understand the metabolism of Saccharomyces cerevisiae var. boulardii and optimize conditions for wort recipe and temperature profile.

Summary: The addition of probiotics to non-dairy frozen desserts can be impacted by raw material, ingredients, and processing steps, which may affect probiotic viability. Suitable characteristics were observed for probiotic non-dairy frozen desserts made from vegetable extracts or fruits, but further studies are needed to determine the health effects after consumption.

Summary: There is a need for standardized in vitro models of the human intestinal tract to study intestinal health without using animals. The Caco-2 cell line is a widely accepted and characterized model for studying intestinal drug transport, host-microbe interactions, and toxicity. We investigated the effect of different experimental variables on gene expression using transcriptome analysis of Caco-2 cells grown on permeable membranes. Our analysis revealed a weak association between experimental variables and gene expression, possibly due to heterogeneity in cell culture practice and inadequate reporting. This highlights the need for improved reporting protocols and serves as a template for future comparative studies.

Summary: Recent reviews have shown that sponge-associated bacteria are valuable sources of structurally diverse secondary metabolites with potent biological activities, making these microbial communities promising for new drug candidates. However, accessing the overall diversity of secondary metabolite biosynthetic potential in bacteria is challenging due to the difficulty in culturing the majority of bacteria in the laboratory. This study investigates the diversity of secondary metabolite biosynthetic gene clusters in metagenomes of bacterial communities associated with three different sponge species and identifies numerous potential gene clusters for the production of novel compounds.

Summary: The infant gut microbiota is influenced by antibiotic exposures and prebiotic oligosaccharides found in breast milk. This study analyzed the stool microbiota of 1023 one-month-old infants and found that breastfeeding and antibiotic exposure both decrease gut microbial diversity, but have different effects on microbiota composition. Other factors such as C-section, homebirth, siblings, and exposure to animals also impact microbiota composition. Understanding these factors can help protect and promote a healthy infant gut microbiota.

Summary: Optimizing bioreactor performance is crucial for sustainable and energy-efficient removal of micropollutants in tertiary treatment. The resident microbial community plays a significant role in bioreactor performance, hence a deeper understanding of community dynamics is essential. By characterizing the microbial communities in three different bioreactors used for organic matter removal, an interdependency between bioreactor performance and microbial community profile was observed. A generalized Lotka-Volterra model was established to understand the interactions in the microbial community and develop strategies for improving bioreactor performance.

Summary: The study investigated the development of gut microbiota in children during the first 14 years of life and its relation to mental health problems in puberty. The analysis of fecal microbiota composition revealed the presence of four distinct microbial clusters in puberty. Prevotella 9 and Faecalibacterium were found to be associated with externalizing behavior and social anxiety, respectively. Further studies are needed to validate these findings and explore the underlying mechanisms.

Summary: A systematic review was conducted to estimate normal reference values for defecation frequency and stool consistency in healthy children up to age 4. The results showed that younger infants have a higher frequency of defecation compared to young children, and the type of feeding and age also have an impact on defecation frequency and stool consistency.

Summary: Antibiotic exposure disrupts infant gut microbiota, but the ability to recover from this disruption depends on the type of antibiotic. This study investigated the effect of two common infant prebiotics, 2'-fucosyllactose (2'-FL) and galacto-oligosaccharides (GOS), on the resilience of the gut microbiota after exposure to amoxicillin/clavulanate. The results showed that the prebiotics supported the recovery of the microbiota and restored the production of beneficial fatty acids.

Summary: Groundwater in The Netherlands is the main source of drinking water, but pesticide presence threatens its quality. Biodegradation is a natural process that can help remove pesticides. However, the oligotrophic groundwater conditions may limit biodegradation due to the lack of microbial communities capable of degrading pesticides. In this study, bioaugmentation with enriched mixed inocula was used to enhance pesticide biodegradation, and the effect of different redox conditions on biodegradation was observed.

Summary: Using genome-centric metagenomics, researchers revealed the phylogenomic placement of the candidate phylum Dadabacteria and predicted the metabolism of sponge-associated members. The results showed that these strains are aerobic heterotrophs capable of synthesizing amino acids, vitamins and cofactors, degrading complex carbohydrates, and exhibiting host-specific gene adaptations. Additionally, fluorescence in situ hybridization revealed the morphology and lifestyle of a member of Ca. Desulfobacterota.

Summary: The imprudent use of antibiotics in food production contributes to the spread of antibiotic resistance. This review emphasizes the need for collaborative efforts and preventive measures to mitigate the problem. Strategies such as heightened awareness, strengthened governance, and integrated surveillance systems are proposed to alleviate the burden of antibiotic resistance.
