Summary: This study presents a catalogue of approximately 50,000 prokaryotic viruses from six WWTPs, significantly increasing the known diversity of AS viruses. Most viral genera are found in multiple AS systems, spanning various archaeal and bacterial phyla, and linked with functional microorganisms controlling nitrogen/phosphorous removal. Notably, Mycobacterium, associated with AS foaming, is connected with 402 viral genera. These findings expand the current AS virus catalogue and provide insights for phage treatment in controlling undesired microorganisms in WWTPs.

Summary: By mining published rumen metagenomes, we constructed a global rumen virome database (RVD) and analyzed its diversity, virus-host linkages, and potential roles in affecting rumen functions. RVD, containing 397,180 species-level viral operational taxonomic units (vOTUs), significantly improves the detection rate of rumen viruses compared with other databases. The rumen virome is predicted to infect core members of the rumen microbiome, carry diverse auxiliary metabolic genes, and likely impact the rumen ecosystem.

Summary: Diverse temperate bacteriophages, including both Siphoviridae and Myoviridae family-types, were found in Pasteurella multocida isolates from different domesticated animal species, potentially playing key roles in the evolution and virulence of this pathogen. Some bacterial hosts were found to harbor multiple prophages, indicating a diverse phage spectrum. Analysis of phage DNA revealed that closely-related strains may have phages with identical restriction endonuclease types, while others may have acquired phages with different types recently.

Summary: Food contamination caused by foodborne pathogens is a major public health concern globally, leading to significant food loss annually. The emergence of antimicrobial resistant bacteria has reignited interest in bacteriophages as antibacterial agents, with their application showing promise in various food production settings. Despite considerable success, challenges remain in terms of technology, environmental safety, and administrative policy for the further development of phage-based antibacterial products.

Summary: In this study, a novel Salmonella phage PS3-1 was identified with high lytic activity against Salmonella Typhimurium. PS3-1 belonged to the class Caudoviricetes with a broad host range, and had relatively short latent period, large burst size, high pH stability and thermal tolerance. Genome sequencing analysis showed that PS3-1 genome consisted of 107,110 bp DNA, without antibiotic resistance and virulence related genes.

Summary: The study found that predation by protozoa and bacteriophage positively correlated with the formation of aerobic granules. The increase in abundance of filamentous phages may promote the structural formation of granules, while the absence of protozoa after chemical treatment delayed the initiation of granules formation.

Summary: Prophages derived from bacteria-infecting viruses play a significant role in influencing bacterial virulence, potentially offering unexplored biotechnological potential. Utilizing designer bacteriophages to target virulence, developing small molecules mimicking phage-derived proteins, and engineering bacteria with phage-derived synthetic circuits could lead to novel therapies against infectious diseases and address antibiotic resistance. Further research into prophage-derived virulence control mechanisms and the mutualistic relationship between temperate phages and bacteria, as well as advancements in synthetic biology, will be crucial for the development and utilization of these antibacterial strategies.

Summary: This study constructed a combination of allicin and Enterobacter cloacae bacteriophage, which effectively lowered the dosage of allicin and overcame bacterial drug-resistance. Allicin interacts with bacterial DNA and disrupts it by cleaving phosphate diester bonds, while the bacteriophage destroys the cell wall and membrane of bacteria. The synergistic effect of this combination improves antibacterial efficiency and avoids drug-resistance.

Summary: Microbial community diversity is correlated with physical environmental stresses. This study investigated bacterial communities in thermal spring sediments and found that both species diversity and metagenomic functional diversity decrease with increasing temperatures. The relationship between the two diversities follows a power function, indicating a quantitatively different manner in which temperature stress limits both taxonomic and functional diversity of microbial communities. The study also highlights the distinct temperature ceilings of various metabolic functions.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
