Skeletonema costatum has been widely used both in extensive and intensive hatchery systems of Marsupenaeus japonicus (Hudinaga, 1942; 1969) and Penaeus monodon (Su et al., 1990). Skeletonema costatum The morphology of strains of Skeletonema Greville emend Sarno et Zingone was examined in LM, TEM, and SEM and compared with sequence data from nuclear small subunit rDNA and partial large subunit rDNA. Toggle navigation. The distribution and speciation of total mercury (THg) and methylmercury (MeHg) were profiled by employing Geobacter metallireducens (G. metallireducens GS-15) as the methylating bacteria. At the end of the culture, the biomass corresponded to 40 ±5 ,gChlall.These cells were considered N-deficient andusedfor nitrate uptakeassays.
