Fine-scale metabolic discontinuity in a stratified prokaryote microbiome of a Red Sea deep halocline

摘要

Additional data provided in Supplementary Table 1. a Black circles, temperature; red triangles, oxygen concentration. b Black circles, salinity obtained from the fractions; red triangles, Salinity obtained from an independent CTD cast. c Black circles, prokaryotic cell count; red triangles, pH. d Black circles, nitrate concentration; red triangles, urea concentration. e Black circles, ammonia concentration; red triangles, nitrite concentration. f Black circles, TDN concentration; red triangles, DOC concentration. g Black circles, isotopic composition of oxygen (δ18O) in nitrate; red triangles, isotopic composition of nitrogen in nitrate. The horizontal dash line represents the limits of the BSI. h Relationship between sodium, manganese, ammonia, nitrate, and sulfate in function of salinity. The oblique dash line represents the correlation between sodium and salinity for visualization purpose.
