Effects of environmental factors dimethylated sulfur compounds their potential role antioxidant system coral holobiont
2014/4/2
Biogenic dimethylsulfide (DMS) and its main precursors, dimethylsulfoniopropionate (DMSP) and dimethylsulfoxide (DMSO), are potential scavengers of reactive oxygen species in marine algae, and these d...
Seasonal change in microbial sulfur cycling in monomictic Lake Fukami-ike, Japan
Seasonal change microbial sulfur cycling monomictic Lake Fukami-ike Japan
2014/4/4
Sulfur budgets and seasonal progression of sulfur cycling processes were investigated in Lake Fukami-ike, a small monomictic lake in Japan. The sulfur isotopic mass balance shows that the main sulfur ...
