Summary: Phloretin from apple inhibits the growth and virulence of Pectobacterium brasiliense (Pb1692), an emerging soft-rot pathogen of potato, by reducing motility, biofilm formation, enzyme secretion, AHL signaling molecule production, and infection. The compound inhibits ExpI activity and downregulates virulence-related genes associated with quorum sensing. Docking simulations suggest a likely mode of action for phloretin's inhibition of virulence.

Summary: The study found that regulating AHLs in marine planktonic assemblages can impact both hydrolytic activities and bacterial community composition. Specific enzymatic activities were impacted as early as 6 hours after AHL amendments in both experiments; after 48 hours, the BCC was significantly affected and correlated with the expression of hydrolytic activities, indicating changes in hydrolytic intensities may drive changes in BCC.

Summary: Quorum sensing (QS) plays a crucial role in phage-host interactions. Shewanella baltica lacks the ability to produce N-acyl-homoserine lactones (AHLs) signal molecules, but it can eavesdrop on exogenous AHLs through its LuxR receptor. However, the involvement of AHLs-mediated QS systems in regulating phage infection in S. baltica remains uncertain. In this study, we found that AHLs modulated phage resistance in S. baltica OS155 by decreasing lipopolysaccharide (LPS)-mediated phage adsorption. Our findings highlight the importance of QS in virus-host interactions and provide valuable insights for developing novel phage strategies for food spoilage control.

Summary: In this study, a QS circuit, ComQXPA-P-srfA, was constructed to dynamically regulate the production of plipastatin. By mutating the original promoter P-srfA, two QS promoters MuP(srfA) and MtP(srfA) were obtained, leading to a 3.5-fold increase in plipastatin yield. Integration of ComQXPA into plipastatin mono-producing M-24 resulted in the highest reported yield of 3850 mg/L. Furthermore, four new plipastatins, including a new type with double bonds in the fatty acid side chain, were identified through analysis of fermentation products.

Summary: In the bacterium Pseudomonas aeruginosa, quorum sensing (QS) can activate the expression of dozens to hundreds of genes. In this study, the researchers investigated how the size and content of the QS regulon can evolve during long-term growth of P. aeruginosa. They found that the QS regulon can undergo a reductive adaptation in response to continuous QS-dependent growth. These findings provide insights into the strain-to-strain variability in the size and content of the P. aeruginosa QS regulon.

Summary: The intermittent electric field stimulated reduction-oxidation coupled process can enhance the biodegradation of azo dyes. Weak intermittent electrostimulation can boost anaerobic cathodic reduction and micro-oxygen-assisted anodic oxidation, promoting the generation of organic compounds to drive biocathode decolorization. Compared to continuous electrostimulation, intermittent electrostimulation exhibits better electron transfer capability and creates a more favorable oxidation-reduction potential. Intermittent electrostimulation also enriches functional consortia with electroactivity and azo dye metabolism capabilities.

Summary: This study found that microplastic exposure significantly affected the microbial reductive dechlorination activities of 2,4,6-trichlorophenol. Different types and sizes of microplastics showed varying effects on dechlorination performance, with PET being the most promoted and PP being the most inhibited. Bio-enrichment on hydrophilic surfaces of microplastics was speculated to be responsible for the favored dechlorination activity. However, extended exposure to microplastics resulted in overall inhibited dechlorination performance.

Summary: The mechanism of microbiome assembly and function driven by cathode potential in an electro-stimulated microbial reductive dechlorination system was investigated. The study found that lower cathode potentials resulted in higher dechlorination rate and increased methane production. The taxonomic and functional structure of the core microbiome also significantly shifted with different cathode potentials. The findings suggest that cathode potential plays an important role in controlling the assembly of the microbiome and its functions.

Summary: Wastewater treatment plants (WWTPs) play a crucial role in removing microplastics (MPs) from urban wastewater. However, there is currently a lack of reliable and efficient methods for extracting MPs, especially in organic-rich matrices such as sludge samples. In this study, a two-step digestion process was developed and optimized, allowing for over 90% extraction efficiency of MPs from sludge samples. The recommended dosage of digestion reagents was found to be 100 ml 30% H2O2 + 100 ml 1 M HNO3 for samples with mixed liquid volatile suspended solids (MLVSS) levels lower than approximately 0.43 g. This study also examined the characteristics of MPs in two WWTPs in Shenzhen, revealing high concentrations of MPs in influent, effluent, and dewatered sludge, with rayon and polyester being the dominant polymers.

Summary: Biofilms are an efficient way of wastewater treatment, but little is known about their formation and development in industrial settings. The interplay between different microhabitats is important for sustaining biofilm formation. SourceTracker analysis showed that the majority of initial biofilm originated from the aggregate, but independent evolution was led by anammox species later on. The microbial interaction pattern and community variation displayed similar trends, but the unknown source proportion of interaction was high throughout the incubation, suggesting different relationships within the distinct microhabitats.

Summary: In this study, a novel coupling strategy of Fe(II)-activated PDS pretreatment with SRB was explored to enhance methane yield from WAS during AD. Results showed that Fe(II)_PDS + SRB and ZVI_PDS + SRB had a similar methane yield, which was higher than other groups. The hydrolysis rate constant in Fe(II)_PDS + SRB was also higher than that in ZVI_PDS + SRB. The concentration of SCFAs and the ultimate utilization efficiency of SCFAs were higher in the Fe(II)_PDS + SRB group, providing a more ideal substrate for methanogens. Furthermore, the study revealed the intrinsic interaction of functional microbial consortia in the Fe(II)_PDS + SRB group.

Summary: The authors prepared a new straw decomposition agent using three fungi (Trichoderma viride, Penicillium, and Phanerochaete chrysosporium burdsall) for lignin, cellulose, and hemicellulose decomposition. The highest efficiency was achieved when the three fungi were mixed in a mass ratio of 1:1:1, resulting in a straw decomposition rate of 45.2% in a 10-day continuous reaction. The depth of straw in soil and the application of composite fertilizer were found to play important roles in straw decomposition. Nutrient release from straw decomposition was observed, with maximum release rates of 48.3% for N, 60.3% for P, and 72.1% for K after 90 days of reaction. The novel straw decomposition agent showed comparable performance to commercial straw decomposition agents, indicating its great potential in practical applications.

Summary: In recent years, biological sulfur (bio-S) has been used in sulfur autotrophic denitrification (SAD) with autotrophic Thiobacillus denitrificans and heterotrophic Stenotrophomonas maltophilia. The growth pattern of T.denitrificans and S.maltophilia showed a linear relationship between OD600 and CFU below certain thresholds. S.maltophilia's DsrA could produce sulfide as an alternative electron donor for T.denitrificans. The interaction of T.denitrificans and S.maltophilia reduced nitrite accumulation and improved denitrification efficiency.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
