TL;DR: Results directly demonstrate that HA and FA are capable of acting as reversible electron-transfer agents using different functional groups, some of which may not be quinones.

TL;DR: NMR analyses of hydrophobic dissolved organic matter (DOM) fractions isolated from a landfill leachate contaminated groundwater near Norman, OK; the Colorado River aqueduct near Los Angeles, CA; Anaheim Lake, an infiltration basin for the Santa Ana River; and groundwater from the Tomago Sand Beds found branched methyl groups and quaternary aliphatic carbon structures that are indicative of terpenoid hydrocarbon precursors.

TL;DR: The pH-dependent equilibrium between NH4+ and NH3, and not the pH- dependent electrostatic attraction between NH 4+ and the TiO2 surface, is responsible for the increase in rates of NH4/NH3 photocatalytic oxidation with increasing pH.

TL;DR: The acid-precipitated (AP) and acid-soluble (AS) fractions of the combined hydrophobic neutral and hydrophilic acid dissolved organic carbon (DOC) were isolated from leachate collected from three municipal landfills of different age and redox conditions as discussed by the authors.

TL;DR: Results are consistent with the hypothesis that ring reduction during syntrophic benzoate metabolism involves a four- or six-electron reduction step and that once cyclohex-1-ene carboxyl-CoA is made, it is metabolized in a manner similar to that in R. palustris.
