Palaeococcus ferrophilus Takai et al. 2000, sp. nov. (Type species of the genus.)
Type strain: (see also StrainInfo.net) DMJ = ATCC BAA-128 = DSM 13482 = JCM 10417.
Sequence accession no. (16S rRNA gene) for the type strain: AB019239.
Etymology: L. n. ferrum, iron; N.L. adj. philus -a -um (from Gr. adj. philos -ê -on), friend, loving; N.L. masc. adj. ferrophilus, iron-loving, indicating that it requires iron for growth in the absence of sulfur.
