Abstract

Here, we report the complete genome sequence of Moorella thermoacetica DSM 2955T, an acetogenic bacterium, which uses the Wood–Ljungdahl pathway for reduction of H2 + CO2 or CO. The genome consists of a single circular chromosome (2.62 Mb).

Highlights

  • We report the complete genome sequence of Moorella thermoacetica DSM 2955T, an acetogenic bacterium, which uses the Wood–Ljungdahl pathway for reduction of H2 ؉ CO2 or CO

  • We determined the genome sequence of one of the type strains of Moorella thermoacetica DSM 2955T, originally named Clostridium thermoaceticum, which was isolated from horse feces in 1942 [1]

  • Since isolation of M. thermoacetica, the strains DSM 521T and ATCC 39073 were used as model acetogens for elucidating the biochemistry of the Wood-Ljungdahl pathway [3, 4]

Summary

Introduction

We report the complete genome sequence of Moorella thermoacetica DSM 2955T, an acetogenic bacterium, which uses the Wood–Ljungdahl pathway for reduction of H2 ؉ CO2 or CO. We determined the genome sequence of one of the type strains of Moorella thermoacetica DSM 2955T, originally named Clostridium thermoaceticum, which was isolated from horse feces in 1942 [1]. About 40 years later, Kerby and Zeikus [2] obtained the original isolated strain from Elizabeth McCoy as a “dried spore stock in soil” and showed that this strain uses H2 ϩ CO2 as its sole carbon and energy source. These were major differences from the previously submitted type strain (DSM 521T), and M. thermoacetica DSM 2955T was deposited in “Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH” (DSMZ) as the second type strain of the species.
