Long-term photochemical and microbial decomposition of wetland-derived dissolved organic matter with alteration of13 C:12C mass ratio
photochemical microbial decomposition wetland-derived dissolved organic matter alteration of13 C:12C mass ratio
2014/4/18
We investigated the long-term photochemical and microbial decomposition of biologically recalcitrant humiclike dissolved organic matter (DOM) leached from a vascular wetland plant, the common rush (Ju...
Photochemical control of copper complexation by dissolved organic matter in Rocky Mountain streams, Colorado
Photochemical control of copper complexation dissolved organic matter Rocky Mountain streams Colorado
2014/4/23
We investigated photochemical, seasonal, and source effects on copper (Cu) complexation by dissolved organic matter (DOM). Cu-DOM complexation regulates Cu toxicity by decreasing the activity of the c...
Microbial and photochemical reactivity of fluorescent dissolved organic matter in a coastal upwelling system
Microbial and photochemical reactivity fluorescent dissolved organic matter coastal upwelling system
2014/5/4
We observed significant changes in the dissolved oxygen content and the fluorescence of humic substances and dissolved aromatic amino acids after 24 h light and dark incubations in the coastal upwelli...
Biological and photochemical production of dissolved gaseous mercury in a boreal lake
Biological and photochemical production dissolved gaseous mercury boreal lake
2014/5/19
We used in situ experiments and measured depth profiles of dissolved gaseous mercury (DGM) to investigate the relative contribution of photochemical versus biological processes on the production of DG...
Photochemical effects on the interaction of enzymes and dissolved organic matter in natural waters
enzymes dissolved organic matter natural waters
2014/5/21
Extracellular enzymes such as phosphatase (Pase) and glucosidase (Gase) can be inactivated in natural waters through photochemical processes. In this study, we examined the mechanisms involved in enzy...
Photochemical reactivity of siderophores produced by marine heterotrophic bacteria and cyanobacteria, based on characteristic Fe(III) binding groups
Photochemical reactivity siderophores produced marine heterotrophic bacteria cyanobacteria Fe(III) binding groups
2014/5/20
Siderophores, high-affinity Fe(III) ligands produced by microorganisms to facilitate iron acquisition, might contribute significantly to dissolved Fe(III) complexation in ocean surface waters. In prev...
