Download scientific diagram | | Cellular fluorescence intensity and cell size as a function of enrichment substrate on a subset of basalt enrichments (sample 30R-1A). The circle size indicates the average cellular area (mm 2 ) as measured by epi-fluorescence microscopy. The standard deviation for the cellular area of each sample is roughly 46% based on the following number of cells counts for each treatment: Host Rock (n = 28); No addition (n = 41); CH 3 COONa (n = 38); CH 4 (n = 62); NaHCO 3 (n = 43); NaHCO 3 + NH 4 Cl (n = 39); NaHCO 3 + NaNO 3 (n = 36); NH 4 Cl (n = 35); NaNO 3 (n = 38). Symbols ++ and + indicate analysis of variance P-values of <0.01 and <0.05, respectively, versus Host rock or No addition; and * * indicate P < 0.01 versus CH 3 COONa, CH 4 or NaHCO 3 . from publication: Nitrogen Stimulates the Growth of Subsurface Basalt-associated Microorganisms at the Western Flank of the Mid-Atlantic Ridge | Oceanic crust constitutes the largest aquifer system on Earth, and microbial activity in this environment has been inferred from various geochemical analyses.
