Elevated production of dimethylsulfide resulting from viral infection of cultures of Phaeocystis pouchetii
Article Abstract:
The marine phytoplankton Phaeocystis pouchetii plays a major role in the biogeochemical cycle of dimethyl sulfide (DMS). Viral lysis of the phytoplankton cells can be a significant factor affecting DMS concentrations in sea-water. Batch cultures of P. pouchetii were infected with a strain-specific viral isolate, and 20 hours later, DMS concentrations were four times higher than in control cultures. After 45 hours, the DMS concentrations were eight times higher in the virally infected cultures than in the controls.

Characterization of dissolved organic phosphorus in coastal seawater using ultrafiltration and phosphohydrolytic enzymes
Article Abstract:
Ultrafiltration and phosphohydrolytic enzymes have been used to characterize dissolved organic phosphorus (DOP) in samples from river and coastal areas of Tokyo Bay, Japan. Topics discussed include the applicability of ultrafiltration and enzymatic hydrolysis for characterization of DOP and possible forms of nonreactive DOP.
