Unraveling Mechanisms in Environmental Organic Processes by Mineral and Biological Catalysts
TITLE: Disproportionate carbon dioxide efflux in bacterial metabolic pathways for different organic substrates leads to variable contribution to carbon use efficiency —ABSTRACT: Microbial organic matter turnover is an important contributor to terrestrial carbon dioxide (CO2) budget. Partitioning of organic carbons
TITLE: Phosphorus recycling by mineral‑catalyzed ribonucleotide cleavage on iron and manganese oxides —ABSTRACT: Phosphorus is an essential element influencing both food security via plant fertilization, and water pollution through excessive phosphorus use, yet the phosphorus cycle in ecosystems is poorly
TITLE: Electrostatic coupling and water bridging in adsorption hierarchy of biomolecules at water–clay interface —ABSTRACT: Clay minerals are implicated in the retention of biomolecules within soil organic matter in many soil environments. Spectroscopic studies have proposed several mechanisms for biomolecule
TITLE: Microbially induced precipitation of silica by anaerobic methane-oxidizing consortia and implications for microbial fossil preservation —ABSTRACT: Authigenic carbonate minerals can preserve biosignatures of microbial anaerobic oxidation of methane (AOM) in the rock record. It is not currently known whether
TITLE: An integrated systems-biology approach reveals differences in formate metabolism in the genus Methanothermobacter —ABSTRACT: Methanogenesis allows methanogenic archaea to generate cellular energy for their growth while producing methane. Thermophilic hydrogenotrophic species of the genus Methanothermobacter have been recognized as
TITLE: Physiological and evolutionary contexts of a new symbiotic species from the nitrogen-recycling gut community of turtle ants —ABSTRACT: While genome sequencing has expanded our knowledge of symbiosis, role assignment within multi-species microbiomes remains challenging due to genomic redundancy and
TITLE: Complex regulation in a Comamonas platform for diverse aromatic carbon metabolism –ABSTRACT: Critical to a sustainable energy future are microbial platforms that can process aromatic carbons from the largely untapped reservoir of lignin and plastic feedstocks. Comamonas species present
TITLE: Selectivity in Enzymatic Phosphorus Recycling from Biopolymers: Isotope Effect, Reactivity Kinetics, and Molecular Docking with Fungal and Plant Phosphatases –ABSTRACT Among ubiquitous phosphorus (P) reserves in environmental matrices are ribonucleic acid (RNA) and polyphosphate (polyP), which are, respectively, organic
TITLE: Metabolomics analysis of unresolved molecular variability in stoichiometry dynamics of a stream dissolved organic matter –ABSTRACT: Broad molecular classification based on stoichiometric ratio relationships has been used extensively to characterize the chemical diversity of aquatic dissolved organic matter (DOM).
TITLE: Dynamic utilization of low-molecular-weight organic substrates across a microbial growth rate gradient –Aim: Low-molecular-weight organic substances (LMWOSs) are at the nexus between microorganisms, plant roots, detritus, and the soil mineral matrix. Nominal oxidation state of carbon (NOSC) has been
