Abstract

The type strain of Tessaracoccus lapidicaptus was isolated from the deep subsurface of the Iberian Pyrite Belt (southwest Spain). Here, we report its draft genome, consisting of 27 contigs with a ~3.1-Mb genome size. The annotation revealed 2,905 coding DNA sequences, 45 tRNA genes, and three rRNA genes.

Highlights

  • Members of the genus Tessaracoccus are Gram-positive, nonmotile, nonsporulating, and facultative anaerobic actinobacteria [1]

  • T. lapidicaptus was recently isolated from a 297-m-deep sample obtained from a drilling project that aimed to intersect the groundwater interacting with the massive pyrite minerals present in the Iberian Pyrite Belt subsurface [4]

  • This environment is of special interest, as underground microbial oxidation of pyrite has been hypothesized to be responsible for the unique characteristics of Río Tinto (“Red River”), a natural extremely acidic stream with high concentrations of heavy metals [5]

Summary

Introduction

Members of the genus Tessaracoccus are Gram-positive, nonmotile, nonsporulating, and facultative anaerobic actinobacteria [1]. T. profundi and T. lapidicaptus, have been isolated from deep-subsurface samples [2, 3]. T. lapidicaptus was recently isolated from a 297-m-deep sample obtained from a drilling project that aimed to intersect the groundwater interacting with the massive pyrite minerals present in the Iberian Pyrite Belt (southwest Spain) subsurface [4].
