Unraveling Mechanisms in Organic Processes by Natural Mineral and Biological Catalysts
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
TITLE: Advancements in 13C isotope tracking of synergistic substrate co-utilization in Pseudomonas species and implications for biotechnology applications –ABSTRACT: Pseudomonads are well-known to thrive in diverse and complex nutritional habitats, and these capabilities make Pseudomonas species attractive as whole-cell
TITLE: The Metabolome of Associations Between Xylem-Feeding Insects and their Bacterial Symbionts –ABSTRACT: Metabolomics has increasingly led to important insights in chemical ecology by identifying environmentally relevant small molecules that mediate inter-organismal interactions. Nevertheless, the application of metabolomics to
TITLE: A non-derivatized method for simultaneous quantitation of proteinogenic, urea-cycle, and acetylated amino acids by liquid chromatography–high-resolution mass spectrometry –ABSTRACT: The quantification of amino acids as freely dissolved compounds or from hydrolyzed peptides and proteins is a common endeavor
TITLE: Adverse Metabolic Outcomes in Soil Pseudomonas Species Exposed to Polyethoxylated Tallow Amine and Glyphosate –ABSTRACT: Polyethoxylated tallow amine (POEA) is a common surfactant used in glyphosate-based herbicide formulations to enhance the bioavailability of the active herbicide ingredient.
