Urban vegetation varies with socio-economic gradients, as lower-income neighborhoods often host sparser and less diverse green spaces. This disparity may affect respiratory health by influencing exposure to bioaerosols. Understanding the characteristics of this aerobiome could help anticipate ris ...

Phosphate-solubilizing bacteria (PSB) are well-known for their ability to convert nonbioavailable phosphates into bioavailable forms, however, research on PSB that possess both phosphate solubilization and crude oil degradation capabilities in marine environments has not yet been explored, and the role of these bacteria in microbial remediation of petrole ...

Endophytes asymptomatically infect virtually all plant species, yet little is known about endophyte community assembly and diversity within the woody tissues of forest trees. We utilised phylogenetic null models of alpha (ses.MNTDab and ses.MPDab) and beta diversity (ses.ßMNTDab and ses.ßMPDab) to infer the role of deterministic and stochastic ecological ...

Inefficient electron transfer is one of the main challenges in practical denitrification applications. To address this issue, a novel ternary mediator functional material (Mxene@Fe-TA) was successfully synthesized, which exhibited pseudocapacitive properties to facilitate electron mediation and distribution. Batch experiments revealed that 50 mg/L MXene@F ...

The heteroresistance phenotype refers to the presence of bacterial subpopulations with reduced antibiotic susceptibility compared with the main population. Mathematical modelling and computer simulations suggest that heteroresistance can lead to negative treatment outcomes and finally, treatment failure. Due to the low frequency and resistance level of re ...

Due to the oligotrophic marine environment, the lack of phosphorus is one of the key factors limiting the oil biodegradation ability of microorganisms after the oil spill occurs. Overcoming phosphorus deficiency has become an urgent problem. In this study, a phosphate-solubilizing bacteria, named Bacillus subtilis PSB-1, with the crude oil degradation eff ...

Human activities such as agriculture and urban development are linked to water quality degradation. Canada represents a large and heterogeneous landscape of freshwater lakes, where variations in climate, geography and geology interact with land cover alteration to influence water quality differently across regions. In this study, we investigated the influ ...

Lakes are sentinels of environmental changes within their watersheds including those induced by a changing climate and anthropogenic activities. In particular, contamination originating from point or non-point sources (NPS) within watersheds might be reflected in changes in the bacterial composition of lake water. We assessed the abundance of potentially ...

Gut-microbiota membership is associated with diverse neuropsychological outcomes, including substance use disorders (SUDs). Here, we use mice colonized with Citrobacter rodentium or the human ?-Proteobacteria commensal Escherichia coli HS as a model to examine the mechanistic interactions between gut microbes and host responses to cocaine. We find that co ...

The incidence and of bacterial infections, and resulting mortality, among cancer patients is growing dramatically, worldwide. Several therapeutics have been reported to have dual anticancer and antibacterial activity. However, there is still an urgent need to develop new drug delivery strategies ...

Siderophores are high-affinity small-molecule chelators employed by bacteria to acquire iron from the extracellular environment. The Gram-negative bacterium Escherichia coli synthesizes and secretes enterobactin, a tris-catechol siderophore. Enterobactin is synthesized by six cytoplasmic enzyme activities: EntC, EntB (isochorismatase (IC) domain), EntA, E ...
