A First Analysis of Metallome Biosignatures of Hyperthermophilic Archaea

Table 1

Metal concentrations measured in the NM (no metal) growth medium for each microorganism. The values are the initial or starting concentrations in each medium, prior to cell inoculation. Concentrations were measured via ICP-MS. E. coli aerobic Ec (a); E. coli grown under anaerobic conditions Ec (an); P. furiosus; methanogen, M. jannaschii. Some values are below detection (BD): M. jannaschii detection limits for Zn and Cu are 5 and 0.05 μg/L, respectively.

Microbial growth medium	Metal concentration (μg/L)
	Zn	Fe	Mn	Cu	Mo	Ni	Co	W
E. coli (a)	488.13	260.08	7.59	6.18	4.95	3.71	3.56	0.93
E. coli (an)	404.00	258.18	7.66	0.53	3.99	4.30	3.35	0.88
P. furiosus	352.55	24.63	1.84	0.19	10.14	3.10	2.27	0.28
M. jannaschii	BD	614.60	1229.63	BD	71.76	94.74	79.27	0.90
