Summary: This study found that biofilm can enhance the adsorption capacity of microplastics to copper and lead, while the influence of UV radiation is minimal. According to modeling analysis, adsorption on V-PS is dominated by intra-particle diffusion, while the adsorption rate on UV-PS and Bio-PS is mainly controlled by binding diffusion. Bio-PS has the strongest adsorption capacity and the adsorption mechanisms include physical adsorption, chemisorption, and biosorption.

Summary: In modern sheep production systems, efforts are being made to reduce fat deposition costs by altering nutrient use to produce leaner carcasses. Limited research has been done on the effect of rumen microbiome on fat deposition, but this study identified variations in microbial populations in the rumen among sheep with different fat deposition phenotypes, which could help in developing strategies to manipulate rumen microbiota for improved production performance. Extensive study of sheep rumen microbiota has been conducted, but their role in regulating fat deposition remains unclear. This study aimed to identify correlations between fat deposition-related phenotypes and the impact of microbiota on changes in body fat accumulation, identifying 29 ruminal bacteria that may be key drivers of different fat deposition levels.

Summary: This study found that the microbial biofilm communities near mariculture areas can affect the settlement of coral larvae. The biofilm farthest from the mariculture area had a higher effectiveness in inducing the settlement of Acropora tenuis larvae. These biofilms were characterized by a greater proportion of crustose coralline algae and gammaproteobacterial taxa, while biofilms closer to the mariculture zone had a higher proportion of cyanobacteria and no crustose coralline algae. These findings suggest that nutrient enrichment from mariculture activities can alter the composition of biofilm-associated microbiome and indirectly affect coral larval settlement.

Summary: The study investigated the impact of biocides and nanoparticles on microbial diversity in a hydraulic fracturing impacted stream. The results showed that different types of nanoparticles led to a decrease in bacterial abundance, while biocide-amended treatments saw an increase in microbial abundance. Differentially enriched taxa were observed in biocide and nanoparticle treatments compared to controls, indicating that nanoparticles slightly altered the microbial community composition. The study suggests the potential use of nanoparticles as an alternative to biocides in certain settings.

Summary: This study compares the microbial communities and their functions in oxygen-depleted and oxygen-limited paddy soil. It finds that oxygen-limited soil has a higher concentration of methylmercury and enhances microbial activity, especially in metabolic pathways related to methylation. The research suggests that insufficient oxygen input in flooded paddy soil increases the risk of human exposure to methylmercury from rice consumption.

Summary: This study compared four different microbial community fingerprinting methods for characterizing the full-scale anaerobic digestion microbiome, with cytometric fingerprinting through flow cytometry proving to be a reliable, fast method for holistic monitoring. The complementary identification of key features through other methods could give rise to a direct interpretation of anaerobic digestion process performance.

Summary: This study analyzed the microbiota in the lung tissue and airway luminal mucus of PWCF patients and compared them to disease characteristics and lung damage. The results showed significant differences in microbial communities between different groups, but also overlap. The luminal mucus of PWCF had lower microbial diversity and higher dominance. Variability in ecological parameters was observed both between and within patients, but no clear relationship was found between ecological parameters and disease characteristics.

Summary: This study investigates the impact of long-term contamination on the soil microbiome composition and diversity at an urban brownfield in Los Angeles. The findings suggest that the presence of heavy metals and organic pollutants shape the soil microbiome diversity, and certain bacteria and fungi show tolerance to these contaminants. The study recommends incorporating DNA-based multi-marker microbial community profiling in brownfield site assessment and restoration.

Summary: Microbial communities in coral reef sediments reflect the environmental conditions and can be influenced by human activities. The study found high abundance of Pseudomonadota, Planctomycetota, and Bacteroidota in the sediments of Liuqiu Island, indicating eutrophic environments. The microbial communities showed temporal variations and potential response to strong climate events like typhoons or heavy rainfall.

Summary: This study investigated the degradation of SMX and the response of microbial communities to different initial concentrations of SMX in MFCs. It was found that the highest SMX removal efficiency was achieved at 5 mg/L, while high concentration of SMX inhibited electron transfer. The 16S rRNA high-throughput sequencing revealed significant shifts in anode biofilm communities with different initial SMX concentrations in MFCs.

Summary: Electrolytic manganese residue poses potential threats to the environment and requires eco-friendly treatment. Composting has been found to effectively passivate heavy metals and mitigate their ecotoxicity. Inoculation of Phanerochaete chrysosporium promotes the passivation of manganese, prolongs the thermophilic period, and enriches the microbial community structure.

The incorporation of silver ions reduced biofilm formation, leading to the highest maximum power density from SPEEK + 7.5% Ag membrane after three months of MFC operation. Microbial community analysis identified microbes contributing to electron transfer.

Summary: The study reveals that violet LED irradiation significantly reduces the relative abundance of Fusobacterium species in the oral microbiome, while leading to a significant increase in species such as Veillonella and Campylobacter. This method shows potential for adjusting the balance of the oral microbiome without inducing antibiotic resistance.

Summary: This study comprehensively characterizes the cavity of a 150 mm FPI with a novel symmetric design, showing that the design effectively limits the combined effects of pre-load and gravity forces. It also identifies a tilt variation between the plates of the interferometer during spectral scan, which can be corrected. The study demonstrates the satisfactory dynamical response of the new system to typical operational scenarios. It concludes that large, fully symmetric FPIs can be safely used in solar observations.

Summary: Observations suggest that carbon monoxide (CO) lines are formed at approximately 530-650 km in the quiet Sun, rather than at lower layers from the photosphere to the chromosphere. It was found that there were seven long-lived cooling events in the region surrounding a large pore, but they were not visible in the three atomic lines. These findings may be related to the magnetic canopy field surrounding the pore.

Summary: In this study, observations of a solar magnetic network region using ALMA and IBIS were presented. The measurements of local gas temperatures provided by ALMA were compared with the temperature diagnostics provided by non-LTE inversions using STiC. The use of column mass as the reference height scale and the treatment of non-LTE hydrogen ionization improved the accuracy of atmospheric profiles and the agreement between inferred chromospheric temperatures and ALMA measurements. However, the poor constraints on chromospheric electron density introduced uncertainties in determining the height(s) of formation of the millimeter continuum and the temperatures derived from spectral lines.

Summary: Microalgae are promising sources of fuels and chemicals. Efficient process control for microalgal cultivations requires on-line sensing of process variables. Optical sensors play a central role in monitoring the physical and chemical environment, while on-line sensors for biological variables are still in an earlier developmental stage and rely on indirect measurement and extensive data processing.
