TITLE: Quantitative Spectroscopic Analysis of Water Populations in the Hydrated Nanopore Environments of a Natural Montmorillonite –ABSTRACT: Smectite clays are implicated in solute trapping in natural and engineered processes. Here we evaluated 23Na solid-state nuclear magnetic resonance (NMR) and thermogravimetric

TITLE: Effects of Phosphonate Herbicides on the Secretions of Plant-Beneficial Compounds by two Plant Growth-Promoting Soil Bacteria: A Metabolomics Investigation –ABSTRACT: Plant growth-promoting rhizobacteria (PGPR) that colonize plant roots produce a variety of plant-beneficial compounds, including plant-growth regulators, metal-scavenging compounds,

TITLE: Phosphonate Herbicide Interactions with Quartz, Montmorillonite, and Quartz-Enriched Agricultural Soil: Molecular Modeling Simulations and Adsorption-Desorption Experiments –ABSTRACT: Phosphonate-based herbicides are extensively used in agriculture. Glyphosate was long considered immobile in soils due to strong complexation with metal oxides, but

TITLE: Molecular Coordination, Structure, and Stability of Metal-Polyphosphate Complexes Resolved by Molecular Modeling and X-ray Scattering: Structural Insights on the Biological Fate of Polyphosphate –ABSTRACT: Polyphosphate-accumulating organisms (PAOs), which can store high levels of phosphate (Pi) in the form of

TITLE: Probing the Fate of Different Structures of Beta-Lactam Antibiotics: Hydrolysis, Mineral Capture, and Influence of Organic Matter –ABSTRACT: Beta-lactam antibiotics, which are used extensively in human and veterinary applications, are commonly detected in surface waters. To examine how the

TITLE: Redox-Related Metabolic Dynamics Imprinted on Short-Chain Carboxylic Acids in Soil Water Extracts: A 13C-Exometabolomics Analysis –ABSTRACT: Soil microbial metabolism is critical to carbon cycling, but direct annotation of metabolic activities is challenging. Here, we present an exometabolomics approach coupled

TITLE: Hierarchical reactivity of enzyme-mediated phosphorus recycling from organic mixtures by Aspergillus niger phytase –ABSTRACT: Biological recycling of inorganic phosphorus (Pi) from organic phosphorus (Po) compounds by phosphatase-type enzymes, including phytases, is an important contributor to the pool of bioavailable

TITLE: Hierarchical routing in carbon metabolism favors iron-scavenging strategy in iron-deficient soil Pseudomonas species –ABSTRACT: High-affinity iron (Fe) scavenging compounds, or siderophores, are widely employed by soil bacteria to survive scarcity in bioavailable Fe. Siderophore biosynthesis relies on cellular carbon

TITLE: Ecophysiological study of Paraburkholderia sp. 1N under soil solution conditions: Dynamic substrate preferences and characterization of carbon use efficiency –ABSTRACT: We used time-resolved metabolic footprinting, an important technical approach used to monitor changes in extracellular compound concentrations during microbial

TITLE: Syntrophic splitting of central carbon metabolism in host cells bearing functionally different symbiotic bacteria –ABSTRACT: Insects feeding on the nutrient-poor diet of xylem plant sap generally bear two microbial symbionts that are localized to different organs (bacteriomes) and provide
