Initial Reports Volume 187
Chapter 6, Table T2. Rock samples incubated for enrichment cultures and prepared for DNA analysis and electron microscope studies and microspheres evaluated for contamination.

Notes: * = Microcosm for iron and sulfur (Fe/S) or manganese (Mn) redox cycles; SEM = scanning electron microscope; TEM = transmission electron microscopy; ** = contamination test; X = sample prepared on board.
