Desulfotomaculum carboxydivorans sp. nov., a novel sulfate-reducing bacterium capable of growth at 100% CO.

International journal of systematic and evolutionary microbiology 55 (Pt 5)
PMID : 16166725 DOI  :   10.1099/ijs.0.63780-0    
Abstract >>
A moderately thermophilic, anaerobic, chemolithoheterotrophic, sulfate-reducing bacterium, strain CO-1-SRB(T), was isolated from sludge from an anaerobic bioreactor treating paper mill wastewater. Cells were Gram-positive, motile, spore-forming rods. The temperature range for growth was 30-68 degrees C, with an optimum at 55 degrees C. The NaCl concentration range for growth was 0-17 g l(-1); there was no change in growth rate until the NaCl concentration reached 8 g l(-1). The pH range for growth was 6.0-8.0, with an optimum of 6.8-7.2. The bacterium could grow with 100% CO in the gas phase. With sulfate, CO was converted to H(2) and CO(2) and part of the H(2) was used for sulfate reduction; without sulfate, CO was completely converted to H(2) and CO(2). With sulfate, strain CO-1-SRB(T) utilized H(2)/CO(2), pyruvate, glucose, fructose, maltose, lactate, serine, alanine, ethanol and glycerol. The strain fermented pyruvate, lactate, glucose and fructose. Yeast extract was necessary for growth. Sulfate, thiosulfate and sulfite were used as electron acceptors, whereas elemental sulfur and nitrate were not. A phylogenetic analysis of 16S rRNA gene sequences placed strain CO-1-SRB(T) in the genus Desulfotomaculum, closely resembling Desulfotomaculum nigrificans DSM 574(T) and Desulfotomaculum sp. RHT-3 (99 and 100% similarity, respectively). However, the latter strains were completely inhibited above 20 and 50% CO in the gas phase, respectively, and were unable to ferment CO, lactate or glucose in the absence of sulfate. DNA-DNA hybridization of strain CO-1-SRB(T) with D. nigrificans and Desulfotomaculum sp. RHT-3 showed 53 and 60% relatedness, respectively. On the basis of phylogenetic and physiological features, it is suggested that strain CO-1-SRB(T) represents a novel species within the genus Desulfotomaculum, for which the name Desulfotomaculum carboxydivorans is proposed. This is the first description of a sulfate-reducing micro-organism that is capable of growth under an atmosphere of pure CO with and without sulfate. The type strain is CO-1-SRB(T) (=DSM 14880(T)=VKM B-2319(T)).

Abstract >>
Desulfotomaculum nigrificans and D. carboxydivorans are moderately thermophilic members of the polyphyletic spore-forming genus Desulfotomaculum in the family Peptococcaceae. They are phylogenetically very closely related and belong to 'subgroup a' of the Desulfotomaculum cluster 1. D. nigrificans and D. carboxydivorans have a similar growth substrate spectrum; they can grow with glucose and fructose as electron donors in the presence of sulfate. Additionally, both species are able to ferment fructose, although fermentation of glucose is only reported for D. carboxydivorans. D. nigrificans is able to grow with 20% carbon monoxide (CO) coupled to sulfate reduction, while D. carboxydivorans can grow at 100% CO with and without sulfate. Hydrogen is produced during growth with CO by D. carboxydivorans. Here we present a summary of the features of D. nigrificans and D. carboxydivorans together with the description of the complete genome sequencing and annotation of both strains. Moreover, we compared the genomes of both strains to reveal their differences. This comparison led us to propose a reclassification of D. carboxydivorans as a later heterotypic synonym of D. nigrificans.
