TITLE: Lithium isotope behaviour during basalt weathering experiments amended with organic acids –ABSTRACT: Lithium (Li) isotopes are a tracer of silicate weathering processes, but how they react to different components of organic and plant-assisted weathering is poorly known. To examine

TITLE: Strategies of organic phosphorus recycling by soil bacteria: Acquisition, metabolism, and regulation –ABSTRACT: Critical to meeting cellular phosphorus (P) demand, soil bacteria deploy a number of strategies to overcome limitation in inorganic P (Pi) in soils. As a significant

TITLE: Analogous Metabolic Decoupling in Pseudomonas putida and Comamonas testosteroni Implies Energetic Bypass to Facilitate Gluconeogenic Growth –ABSTRACT: Gluconeogenic carbon metabolism is not well understood, especially within the context of flux partitioning between energy generation and biomass production, despite the

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
