Summary: The study found that passive treatment of streams impaired by acid mine drainage is more effective at restoring microbial communities in water and leaf habitats, while sediment microbial communities show poorer recovery. Microbial community composition in different habitats is synergistically affected by habitat type and AMD impact, with community similarity increasing with AMD severity. The absence of certain microbial taxa in sediment communities at treated and untreated AMD sites corresponds to higher NH4+ concentrations, suggesting the presence of iron oxyhydroxide precipitate as a factor.

Summary: Free-living, particle attached, and biofilm marine microbial communities display distinct characteristics in terms of environmental conditions and sources of organisms. Different coastal areas show varied impacts of water quality and resources on the lifestyles of marine microbial communities.

Summary: Biofilm bioreactors have become increasingly popular in the wastewater industry due to their ability to achieve higher cell densities and reaction rates. A new method using a biocoating or living paint made from a synthetic biofilm has been introduced to improve the viability and formation speed of nitrifying bacteria. This method utilizes two colloid science phenomena to encapsulate and convert desiccation-sensitive nitrifying bacteria effectively.

Summary: Legionellales-infected water can cause outbreaks of Legionnaires' disease and Pontiac fever, and decontamination is difficult as Legionellales reproduce in eukaryotic microorganisms. Research suggests that Thecofilosea amoebae, particularly in soils and wastewater treatment plants, may serve as potential hosts for endosymbiotic Legionellales, including Legionella. The morphotype, rather than the evolutionary origin, of amoebae seems to determine their suitability as hosts for Legionellales, with a protocol provided for gnotobiotic cultivation of Legionellales and their hosts.

Summary: Graphene shows promise in biointerface applications, effectively restricting biogenic sulfide attack. Single-layered graphene may worsen the attack, while multilayered graphene offers better protection. Defects, such as double vacancy defects and grain boundaries, affect the protection ability of graphene layers.

Summary: HP-29, a newly developed halogenated phenazine, exhibits potent antimicrobial activity with a remarkable minimum inhibitory concentration of 0.08 mu M against methicillin-resistant Staphylococcus aureus (MRSA). In addition to eradicating preformed biofilm through iron starvation, HP-29 is also non-toxic to mammalian cell lines and efficacious in wound infection models.

Summary: The effectiveness of antibiotics is severely impacted by antimicrobial resistance, with multidrug-resistant pathogens being a major public health concern. The main mechanisms by which bacteria develop resistance to antibiotics include altering drug targets, preventing drug entry into cells, efflux pumps, or drug inactivation. Understanding and predicting resistance patterns can lead to better selection of active antibiotics for treating multidrug-resistant infections.

Summary: This study investigated the distribution characteristics and biodiversity of microbial communities in urban residential sewer pipes. The study found differences in spatial distribution of microbial communities, which were influenced by total nitrogen, sulfate, and oxidation-reduction potential. Corrosion differences in different sites were primarily attributed to variations in microbial communities in the upper parts, with sulfate-reducing bacteria and fermentation bacteria playing a major role in concrete corrosion in the bottom part, and sulfur-oxidizing bacteria in the upper part. The middle and end of the sewer pipes faced a greater risk of concrete corrosion compared to the beginning parts.

Summary: The study found that lytic phages can co-transport with bacteria, promoting bacterial colonization of new habitats. This co-transport is analogous to invasion processes in macroecology. In water-unsaturated systems, hyphal transport of bacteria and associated phages plays a crucial role in regulating microbial population fitness and composition.

Summary: Network models and community phylogenetic analyses were used to examine the temporal dynamics of network properties in microbial communities in activated sludge systems. The results showed that during the initial assembly stages, the microbial communities adapted to the activated sludge environment, leading to an increase in network modularity and co-exclusion proportion, and a decrease in network clustering. This suggests niche specialization as a result of the selective pressure of deterministic factors in wastewater treatment plants.

Summary: The research on microbial diversity of the northern pitcher plant Sarracenia purpurea reveals that climate variables, plant size, and midge abundance have direct and indirect effects on microbiome taxonomic and phylogenetic diversity. The results suggest that warmer, wetter sites have greater richness of microbial phylotypes due to the direct and indirect effects of climate and midge abundance.
