Abstract

© 2017 The Author(s). Archaeoglobus fulgidus is the type species of genus Archaeoglobus Stetter 1998, a hyperthermophilic sulfate reducing group within the Archaeoglobi class of the euryarchaeota phylum. Members of this genus grow heterotrophically or chemolithoautotrophically with sulfate or thiosulfate as electron acceptors. Except for A. fulgidus strain 7324 and the candidate species "Archaeoglobus lithotrophicus", which both originate from deep oil-fields, the other members of this genus have been recovered from marine hydrothermal systems. Here we describe the features of the A. fulgidus strain 7324 genome as compared to the A. fulgidus VC16 type strain. The 2.3 Mbp genome sequence of strain 7324 shares about 93.5% sequence identity with that of strain VC16T but is about 138 Kbp longer, which is mostly due to two large 'insertions' carrying one extra cdc6 (cell-cycle control protein 6) gene, extra CRISPR elements and mobile genetic elements, a high-GC ncRNA gene (hgcC) and a large number of hypothetical gene functions. A comparison with four other Archaeoglobus spp. genomes identified 1001 core Archaeoglobus genes and more than 2900 pan-genome orthologous genes.
