A First Analysis of Metallome Biosignatures of Hyperthermophilic Archaea

Figure 3

Pie charts depicting relative microbial abundances of reported metals other than Fe. Iron, as the most abundant metal in all cells, has not been included here to show the apparent differences in the cellular abundances of minor trace metals. The percentages are based on the whole cell acid digest fraction of the NM experiments. The trace metal pattern for the methanogen M. jannaschii is particularly distinct when compared to the other two microorganisms and may be useful as a potential biosignature.
