TABLE 3.

Percentage of total DAPI cells that are either autofluorescent (NP = no probe), labeled with fluorescent probes (CON = control probe; ARC = Archaea probe mix; BAC = Bacteria probe), labeled by microautoradiography (MAR) with ³H-labeled amino acids, or simultaneously labeled with both (probe and ³H-labeled amino acids) for surface and 200-m-deep Mediterranean Sea samples^a
