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

2014/5/21
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
