Bioelectrochemical treatment of oil sands process‐affected water: A comparative study

The Canadian Journal of Chemical Engineering, Volume 103, Issue 12, Page 5819-5831, December 2025.
Comparative Efficiency of microbial fuel cell, microbial electrolysis cell, and microbial electrosynthesis cell systems for oil sands process‐affected water treatment. Abstract In this study, removal of dissolved organic carbon and naphthenic acids (NAs) from oil sands process‐affected water (OSPW) was evaluated in flow‐through microbial fuel cell (MFC)

Microbial Diversity and Connectivity in Deep-Sea Sediments of the South Atlantic Polar Front

Frontiers in Microbiology, 2019
Ultraslow spreading ridges account for one-third of the global mid-ocean ridges. Their impact on the diversity and connectivity of benthic deep-sea microbial assemblages is poorly understood, especially for hydrothermally inactive, magma-starved ridges ...

Influence of Plant Genotype on Nodule‐Associated Bacterial Community Composition and Function in Seasonal Field Pea Varieties

Legume Science, Volume 7, Issue 4, December 2025.
ABSTRACT Legume root nodules host symbiotic rhizobia that are essential for nitrogen fixation but also harbor diverse non‐rhizobial taxa that remain poorly characterized. Field pea (Pisum sativum) cultivars adapted to distinct seasonal growth (spring and winter) offer an opportunity to explore whether host genotype influences nodule‐associated ...

Characteristics of Microbial Diversity and Metabolic Versatility in Dynamic Mid-Okinawa Trough Subsurface Sediments

Journal of Marine Science and Engineering
Large-scale and multi-sample datasets have revealed that microbial diversity and geographic distribution patterns are distinct across various habitats, particularly between hydrothermal vent and cold seep ecosystems.

Dissecting Causal Relationships Between Gut Microbiota Imbalance, Inflammatory Cytokines, and Structural Connectivity in the Brain: A Mendelian Randomization Study

Brain and Behavior, Volume 15, Issue 11, November 2025.
This study identifies causal links between gut microbiota and brain structural connectivity using Mendelian randomization and mediation analyses. Inflammatory cytokines, including RANTES, HGF, and IL‐13, mediate these effects through immune pathways, revealing novel insights into the microbiota‐gut‐brain axis and potential therapeutic targets for ...

A Comprehensive Study of Biohopanoid Production in Alphaproteobacteria: Biosynthetic, Chemotaxonomical, and Geobiological Implications

Geobiology, Volume 23, Issue 6, November/December 2025.
ABSTRACT Bacteriohopanepolyol derivatives (BHPDs) and dia‐ and catagenetic products formed from these bacterial membrane modifiers are extensively used as biomarkers in molecular ecological and geoscience studies. Some BHPDs can be assigned to specific phylogenetic bacterial groups. With the vastly increasing availability of complete bacterial genomes,

Long‐Term Impact of the Largest Environmental Disaster in Latin America (Fundão Dam Failure) on Microbial Communities in Lakes of the Doce River Basin, Brazil

Environmental Microbiology, Volume 27, Issue 9, September 2025.
The collapse of the Fundão dam caused long‐term alterations in the microbiome of lakes in the Doce River basin, with microbial communities closely associated with heavy metals originating from the mining tailings. The findings also highlight potential microbial groups for biomonitoring and bioremediation efforts.

Enhanced understanding of nitrogen fixing bacteria through DNA extraction with polyvinylidene fluoride membrane

Scientific Reports
The rhizobiota, particularly nitrogen-fixing bacteria, play a crucial role in plant functioning by providing essential nutrients and defense against pathogens. This study investigated the diversity of nitrogen-fixing bacteria in a relatively understudied

Nitrous oxide reduction by members of the family Rhodospirillaceae and the nitrous oxide reductase of Rhodopseudomonas capsulata [PDF]

Journal of Bacteriology, 1985
After growth in the absence of nitrogenous oxides under anaerobic phototrophic conditions, several strains of Rhodopseudomonas capsulata were shown to possess a nitrous oxide reductase activity. The enzyme responsible for this activity had a periplasmic location and resembled a nitrous oxide reductase purified from Pseudomonas perfectomarinus. Electron

Farming System and Nematodes Affect the Rhizosphere Microbiome of Tropical Banana Plants

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
The banana crops showed a core microbiome of 77 ASV, mostly belonging to Proteobacteria, Actinobacteria, and Bacilli. Specific groups of bacteria and fungi were linked to each nematode species or feeding group, with a core microbiome of correlated taxa found only when considering nematodes by feeding groups.
