Summary: This study investigated the symbiotic relationship between microalgae and bacteria in the nitrogen cycle through batch cultivation experiments with different concentrations of digestate, using 16S rRNA sequencing and functional gene analysis. The results indicate that microalgae-microbial consortia contribute to the removal of NH4+ and NO2- and accumulation of NO3- in digestate. The study demonstrates the critical role of symbiotic relationships between microalgae and bacteria in biorefinery concepts.

Summary: This study examined the diversity, assembly processes, and functional profiles of bacterial communities in marine sediments of the subtropical Beibu Gulf. Proteobacteria was found to be the dominant phylum, and deterministic processes played a major role in shaping the bacterial communities. The functional groups related to the carbon cycle were the most abundant, followed by nitrogen and sulfur. The composition of the bacterial community was significantly influenced by TC, TP, and TS.

Summary: This study investigated the bacterial diversity and composition of canopy leaves in six dominant tree species in deciduous broad-leaved forests in northeastern China. The results showed that tree species with closer evolutionary distances had similar phyllosphere microbial alpha diversity. The dominant phyla of phyllosphere bacteria were Proteobacteria, Actinobacteria, and Firmicutes. Functional genes of phyllosphere bacteria were mainly involved in amino acid metabolism and carbohydrate metabolism processes. Plant nutrient acquisition and resistance to diseases and pests were found to be the main factors influencing the community structure of phyllosphere bacteria.

Summary: Hospital wastewater contains a variety of human antibiotics and pathogens, with a lack of research on pollutants at treatment plants. Different hospitals showed varying levels of antibiotics and ARGs in their wastewater. The study revealed the co-occurrence of antibiotics, ARGs, and antibiotic-resistant pathogens in hospital wastewater.

Summary: This study tracked the biofilm-dispersed microbial communities of a full-scale drinking water distribution system (DWDS) for three years, before and after the removal of monochloramine. The removal of monochloramine increased total cell counts and led to the emergence of predatory bacteria Bdellovibrio, as well as the replacement of the nitrifying core community with a community potentially metabolizing small organic compounds. However, no increased abundance of Mycobacterium or Legionella was observed in the drinking water distribution system. Co-occurrence analysis revealed a network of bacteria, including Nitrosomonas, Nitrospira, Sphingomonas, and Hyphomicrobium, suggesting that monochloramine supported this biofilm community.

Summary: This study investigated the response of coral bacteria during bleaching by studying bacterial communities from semi-bleached coral in the South China Sea. The results showed that bleaching caused significant changes in coral bacterial communities and increased the abundance of potentially pathogenic bacteria while decreasing the abundance of core probiotics in corals. The study also revealed that bacterial interactions in bleaching coral were more complex than in unbleached coral, leading to significant changes in the coral microenvironment.

Summary: The orientational order of building blocks is a defining property of liquid crystals, which also exists in various biological systems. However, the physical mechanisms behind the orientational order in biological systems have often been overlooked. This study reveals how biological activity leads to orientational ordering in fluid and gel analogs of soft matter systems, and shows the evolution of these ordered structures during biological-activity-driven, disorder-order transformations. The findings have implications for both technological applications and fundamental science.

Summary: This study analyzed the bacterial and eukaryotic microbiota in shrimp aquaculture ponds. The results showed that the bacterial communities in the water were distributed uniformly and relatively stable, while the eukaryotic plankton in the water changed dynamically. The bacterial compositions in the digestive tracts of shrimp differed between ponds and locations.

Summary: A comprehensive understanding of bacterial communities in metal(loid)-contaminated estuarine-coastal habitats is important for improving ecosystem functions. This study collected sediment samples from different sites in Liaoning Province, China to evaluate the relationship between microbial community and metal(loid) contamination. The results showed significant variations in community diversity and composition, primarily influenced by salinity and metal(loid) concentrations. Metal(loid) stress increased metal(loid)-resistant genes, but decreased denitrification genes. Stochastic processes dominated community assembly in estuary offshore sites, while deterministic processes dominated river community assembly mechanisms.

Summary: This study investigated the temporal stability of microbial contamination during cheddar cheese production and found that the timing of processing within a production day can affect the microbial composition of the finished cheese. Furthermore, bacterial growth on food contact surfaces and routine changes in the starter culture may contribute to microbial differences in cheese.

Summary: In this study, the texture properties of Ayran, a Kazakh artisanal fermented milk in Xinjiang, China, were investigated. Six Ayran samples with different texture features were characterized, and their microbiota were analyzed. Lactobacillus and Lactococcus were identified as the core genera influencing the coagulation quality of milk. Additionally, specific genes of Lactobacillus helveticus, Limosilactobacillus fermentum, and Lactococcus lactis were found to be associated with the coagulation quality of fermented milk.

Summary: Due to the high toxicity and bio-accumulation in the food chain, controlling cadmium pollution in wastewater is urgent. In this study, Phragmites australis-activated carbon (PAAC) was modified with mannitol to improve its adsorption efficiency for Cd(II). The modification increased the adsorption capacity of PAAC by 58.59% through the formation of complexes with oxygen-containing functional groups. Precipitation with minerals was found to be a crucial factor for Cd(II) adsorption on activated carbon.

Summary: Candida Tropicalis was used to improve the dewaterability of activated sludge (AS) by degrading EPS in AS, resulting in a decrease in protein, polysaccharide, and hydrophilic amino acids in EPS. The yeast degraded macromolecular organics into smaller molecular ones and direct addition of yeast to AS was more effective in EPS degradation. Addition of 0.75 g/L of wet yeast cells and 24 h of aeration enhanced the dewaterability of AS with a reduction in CST and MLSS. After 30 days of operation, lab-scale continuous SBRs reduced CST and MLSS of AS. FTIR spectroscopy showed a decrease in hydrophilic functional groups. This study presents a new approach for in-situ reduction of AS in wastewater treatment plants.

Summary: Higher cell density has a strong antagonistic effect on filamentous induction, leading to better cell flocculation and settleability. Additionally, the cell density significantly influences yeast cell metabolism, affecting the utilization of phenylalanine and the production of extracellular substances and metabolites. The presence of phenethyl alcohol in metabolites suggests the involvement of quorum sensing in regulating yeast cell transformation in wastewater treatment.
