Abstract

Tolumonas auensis Fischer-Romero et al. 1996 is currently the only validly named species of the genus Tolumonas in the family Aeromonadaceae. The strain is of interest because of its ability to produce toluene from phenylalanine and other phenyl precursors, as well as phenol from tyrosine. This is of interest because toluene is normally considered to be a tracer of anthropogenic pollution in lakes, but T. auensis represents a biogenic source of toluene. Other than Aeromonas hydrophila subsp. hydrophila, T. auensis strain TA 4T is the only other member in the family Aeromonadaceae with a completely sequenced type-strain genome. The 3,471,292 bp chromosome with a total of 3,288 protein-coding and 116 RNA genes was sequenced as part of the DOE Joint Genome Institute Program JBEI 2008.

Highlights

  • Strain TA 4T (= DSM 9187) is the type strain of the species Tolumonas auensis [1], which is the type species of the monotypic genus Tolumonas [1,2]

  • The one yielding the highest score was Cronobacter sakazakii (NC_009778), which corresponded to an identity of 91.8% and an HSP coverage of 100.0%. (Note that the Greengenes database uses the INSDC (= EMBL/National Center for Biotechnology Information (NCBI)/DDBJ) annotation, which is not an authoritative source for nomenclature or classification.) The highest-scoring environmental sequence was GQ479961 ('changes during treated process sewage wastewater treatment plant clone BXHA2'), which showed an identity of 99.2% and an HSP coverage of 97.9%

  • Sequencing, finishing, and annotation were performed by the DOE Joint Genome Institute (JGI)

Summary

Introduction

Strain TA 4T (= DSM 9187) is the type strain of the species Tolumonas auensis [1], which is the type species of the monotypic genus Tolumonas [1,2]. (Note that the Greengenes database uses the INSDC (= EMBL/NCBI/DDBJ) annotation, which is not an authoritative source for nomenclature or classification.) The highest-scoring environmental sequence was GQ479961 ('changes during treated process sewage wastewater treatment plant clone BXHA2'), which showed an identity of 99.2% and an HSP coverage of 97.9%. The most frequently occurring keywords within the labels of environmental samples which yielded hits were 'reduc' (7.7%), 'sludg' (5.6%), 'activ' (4.8%), 'treatment, wastewat' (4.2%) and 'comamonadacea' (4.1%) (31 hits in total).
