Microbially Mediated Ore-Forming Processes and Cell Mineralization [PDF]

open access: yesFrontiers in Microbiology, 2019
Sedimentary black shale-hosted manganese carbonate and oxide ores were studied by high-resolution in situ detailed optical and cathodoluminescence microscopy, Raman spectroscopy, and FTIR spectroscopy to determine microbial contribution in metallogenesis. This study of the Urucum Mn deposit in Brazil is included as a case study for microbially mediated

Gut Microbiota‐Derived Indole‐3‐Propionic Acid Alleviates Diabetic Osteoporosis Through Nrf2‐Mediated Ferroptosis Suppression

open access: yesAdvanced Science, EarlyView.
Diabetes‐associated dysbiosis is accompanied by reduced Clostridium abundance, impaired microbial tryptophan metabolism, and lower circulating indole‐3‐propionic acid (IPA). Exogenous IPA improves trabecular microarchitecture and bone formation and restores Nrf2‐associated antioxidant signaling in bone marrow mesenchymal stem cells, limiting iron ...

Microbial biomass – not diversity – drives soil carbon and nitrogen mineralization in Spanish holm oak ecosystems

open access: yesGeoderma
Soil microbial communities drive essential ecosystem functions, catalyzing biogeochemical cycles and contributing to climate regulation. However, due to the complexity of microbial communities, the magnitude and direction of microbial biomass and ...

Enhanced Endophytic Colonization of Flavobacterium Promotes Plant Resistance to Fusarium Wilt

open access: yesAdvanced Science, EarlyView.
A natural microbial consortium employing a cross‐feeding strategy forms a stratified biofilm that promotes endophytic colonization of auxotrophic Flavobacterium. This enhanced colonization activates plant systemic resistance, effectively suppressing Fusarium wilt.

Biogeochemical sulfide mineralization in the volcanic-hosted Tongguan hydrothermal field, southern Mid-Atlantic Ridge

open access: yesFrontiers in Marine Science
Biogeochemical mineralization is increasingly recognized as a significant factor in the formation of submarine hydrothermal sulfide deposits. While several mechanisms by which hydrothermal organisms may facilitate metal deposition have been documented in

Towards a Compositional Framework for Describing Human Phenotypes

open access: yesAdvanced Science, EarlyView.
The Phenotype Assembly Method (PhenoAM) decomposes phenotype variables into measurable Features and typed Qualifiers, enabling standardized, machine‐readable Phenome Data Elements (PhenoDEs) that preserve measurement context. Applied in the International Human Phenome Project (IHPP), the framework yields 58 371 PhenoDEs and supports component‐level ...

Ammonification Process Is Limited by Transformation of Medium Molecular Weight Nitrogenous Organics but Not Hydrolysis of Proteins

open access: yesAdvanced Science, EarlyView.
A multi‐level analytical framework, integrating protein‐level persistence analysis, nontargeted HRMS formula tracking, peptide‐level proteomics, and targeted monomer quantification under varying redox conditions, together with FMO calculations reveal that ammonification is limited by medium molecular weight nitrogenous multimers.

Hierarchical Nanoplatform Integrating Oxidative–Acidic Microenvironment Remodeling and Bone Homeostasis Modulation for Diabetic Bone Defect Therapy

open access: yesAdvanced Science, EarlyView.
A hierarchical CM/LDH nanoplatform integrates ROS‐scavenging Ce‐MOF nanozymes with acid‐neutralizing CaAl‐LDH and is delivered within GelMA hydrogel to diabetic bone defects. By remodeling the oxidative‐acidic microenvironment, preserving mitochondrial homeostasis, and suppressing mtDNA–cGAS–STING inflammatory signaling, CM/LDH reduces proinflammatory ...

Long-term Impacts of Silvicultural Treatments on Soil Microbial Biomass, Community Composition, and N Mineralization

open access: yes, 2005
This study was conducted in a late-rotation loblolly pine (Pinus taeda L.) plantation to assess the effects of silvicultural treatments (site preparation and vegetation control) on (1) microbial biomass, (2) microbial community composition, and (3 ...
