Desulfotomaculum acetoxidans Widdel and Pfennig 1977 was one of the first sulfate-reducing bacteria known to grow with acetate as sole energy and carbon source. It is able to oxidize substrates completely to carbon dioxide with sulfate as the electron acceptor, which is reduced to hydrogen sulfide. All available data about this species are based on strain 5575T, isolated from piggery waste in Germany. Here we describe the features of this organism, together with the complete genome sequence and annotation. This is the first completed genome sequence of a Desulfotomaculum species with validly published name. The 4,545,624 bp long single replicon genome with its 4370 protein-coding and 100 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Strain 5575T, also known as “Göttingen” strain (= DSM 771 = ATCC 49208 = VKM B-1644 = KCTC 5769) is the type strain of the species Desulfotomaculum acetoxidans [1]. Strain 5575T is the only strain of the species that is available from public culture collections. It was isolated from piggery waste in Göttingen, Germany. Widdel and Pfennig [2] reported the isolation of additional strains from animal manure, rumen content and dung-contaminated freshwater habitats and concluded that members of D. acetoxidans are primarily intestinal bacteria. Unclassified strains with rather high 16S rRNA gene sequence similarity to strain 5575T were reported from rice field soil (AJ012600 and AJ012601, 98%) and from a freshwater sediment in The Netherlands [3]. A complete genome sequence of the strain ‘Desulfotomaculum reducens’ MI-1 was recently determined by the DOE Joint Genome Institute (GenBank accession number NC_009253). However, this strain is only distantly related with D. acetoxidans 5575T, both sharing a 16S rRNA sequence similarity of only 86%, and has no taxonomic status, because the species epithet was never validly published. Here we present a summary classification and a set of features for D. acetoxidans strain 5575T together with the description of the complete genomic sequencing and annotation.

Classification and features

The genus Desulfotomaculum currently represents a rather heterogeneous taxon. The available 16S rRNA gene sequences (GenBank accession numbers AB294139 and NR_026409) of the type strain of Desulfotomaculum guttoideum, DSM 4024, appear to be unrelated to the type species of the genus, but show high similarity to Clostridium sphenoides and C. celerescens, which both belong to cluster XIVa of the clostridia [4]. An investigation of the phenotypic traits of D. guttoideum strain DSM 4024 indicated its affiliation to the species C. sphenoides, which was also confirmed by a DNA-DNA reassociation value above 70% with the type strain of C. sphenoides (unpublished results). This indicates that either the published species description of D. guttoideum is erroneous or the originally described strain is not identical with the culture that was deposited in culture collections. Apart from this species, the genus Desulfotomaculum is paraphyletic and comprises several distinct phenotypic types including mesophilic species, like D. acetoxidans, moderate thermophiles (e.g. D. thermosubterraneum), halophiles (D. halophilum) and alkaliphiles (D. alkaliphilum). The type species of the genus, D. nigrificans, is a moderate thermophile and shares only 85% 16S rRNA gene sequence similarity with D. acetoxidans, indicating that the latter species might have been misclassified. The members of the genus Desulfotomaculum are affiliated to the family Peptococcaceae of the order Clostridiales, within the phylum Firmicutes.

Figure 1 shows the phylogenetic neighborhood of D. acetoxidans strain 5575T in a 16S rRNA based tree. The ten 16S rRNA gene copies in the genome of strain 5575T differ by up to 41 nucleotides (2.6%) from each other, and by up to 35 nucleotides (2.2%) from the previously published 16S rRNA sequence generated from DSM 771 (Y11566). D. guttoideum, DSM 4024, has not been included in the phylogenetic analysis for reasons given above.

The tree was inferred from 1294 aligned characters [5,6] of the 16S rRNA sequence under the maximum likelihood criterion [7] and rooted with the type strain of the type species of the family Peptococcaceae. The branches are scaled in terms of the expected number of substitutions per site. Numbers above branches are support values from 1000 bootstrap replicates if larger than 60%. Lineages with type strain genome sequencing projects registered in GOLD [8] are shown in blue, published genomes in bold.

Vegetative cells of D. acetoxidans 5575T are straight to slightly curved rods with pointed ends and dimensions of 1.0-1.5 µm ×3.5-9.0 µm (Table 1 and Figure 2). Motility is conferred by a single polar flagellum [1]. Cells were originally described to stain Gram-negative [1], which is a typical trait among Desulfotomaculum species, but all Desulfotomaculum strains examined so far by electron microscopy have a cell wall structure of the Gram-positive type [20]. Spherical spores of 1.5 µm diameter are located in a subterminal position and cause a swelling of cells resulting in a typical spindle shaped morphology. Spores are preferentially formed in agar colonies upon prolonged incubation with acetate as substrate. Formation of spores is often accompanied by the production of gas vacuoles that appear as conic refractile areas adjacent to the spores in sporulating mother cells. Growth occurs between 20 and 40°C with an optimum at 36°C. The pH range for growth is 6.6–7.6, with an optimum at 7.1 [1]. The salinity optimum for growth of D. acetoxidans is 1 g/l NaCl and growth is inhibited above 7 g/l NaCl, which is typical for strains showing an adaptation to freshwater habitats [2].

Substrates allowing good growth were found to be acetate and butyrate, whereas long chain fatty acids or carbohydrates were not utilized [2]. In addition, ethanol, n-butanol, iso-butyrate and n-valerate were identified as suitable substrates. With acetate as substrate, only sulfate was reported to be used as electron acceptor, but not sulfite, thiosulfate or fumarate [2]. No fermentative growth on organic substrates in media without sulfate was observed [1]. Biotin was identified as sole growth factor in defined media [2].


Redox difference spectra indicate the presence of membrane bound b-type cytochromes, whereas no cytochromes c or soluble cytochromes were detected. The CO-difference spectrum of the soluble cell fraction revealed presence of a dissimilatory sulfite reductase of the type P582 [1,2]. D. acetoxidans contains only menaquinones, mainly of the MK-7 type and small amounts of MK-6 [21]. Dowling et al. [22] determined the whole-cell fatty acid pattern of D. acetoxidans strain 5575T and found a dominance of straight-chain, even-numbered fatty acids, whereas neither 10-methyl nor cyclopropyl fatty acids were present. The predominant fatty acids this organism were 16:0 (34.0%), 16:1 ω7c (24.4%) and 18:1 ω7c (24.1%), followed by 16:1 ω9 (5.9%) and 16:1 ω5 (4.8%). The abundance of distinct fatty acids in this species apparently depends strongly on the medium composition: It was found that supplementation of the growth medium with volatile fatty acids led to a decreased proportion of even-numbered fatty acids from 99 to 67% [22]; in addition, Londry et al. reported that under conditions of autotrophic growth the proportion of 16:1 fatty acids decreased, whereas 18:1 fatty acids increased compared to growth on acetate as carbon source [23].

Growth conditions and DNA isolation

D. acetoxidans strain 5575T, DSM 771, was grown anaerobically in DSMZ medium 124 [24]at 37°C. DNA was isolated from 1-1.5 g of cell paste using Qiagen Genomic 500 DNA Kit (Qiagen, Hilden, Germany) following the manufacturer's instructions, with a modified protocol for cell lysis (modification LALMP), as described in [25].

Genome sequencing and assembly

The genome of D. acetoxidans strain 5575T was sequenced using a combination of 8 kb and fosmid genomic libraries on a Sanger sequencing platform. The Phred/Phrap/Consed software package (Web Site) was used for sequence assembly and quality assessment. Possible mis-assemblies were corrected with Dupfinisher or transposon bombing of bridging clones [26]. Gaps between contigs were closed by editing in Consed, custom primer walk or PCR amplification. A total of 3,281 Sanger finishing reads were produced to close gaps, to resolve repetitive regions, and to raise the quality of the finished sequence. The error rate of the completed genome sequence is less than 1 in 100,000. Together all sequence types provided 9.2× coverage of the genome. The completed genome sequences of D. acetoxidans contains 46,605 reads.

Genome annotation

Genes were identified using Prodigal [27] as part of the Oak Ridge National Laboratory genome annotation pipeline, followed by a round of manual curation using the JGI GenePRIMP pipeline [28]. The predicted CDSs were translated and used to search the National Center for Biotechnology Information (NCBI) nonredundant database, UniProt, TIGRFam, Pfam, PRIAM, KEGG, COG, and InterPro databases. Additional gene prediction analysis and functional annotation was performed within the Integrated Microbial Genomes Expert Review (IMG-ER) platform [29].

Genome properties

The genome is 4,545,624 bp long with a 41.6% GC content (Table 3 and Figure 3). Of the 4470 genes predicted, 4370 were protein coding genes, and 100 RNAs; 302 pseudogenes were also identified. The majority of the protein-coding genes (65.6%) were assigned with a putative function while the remaining ones were annotated as hypothetical proteins. The distribution of genes into COGs functional categories is presented in Table 4.

Insights from the genome sequence

Heterotrophic substrate utilization

It has been shown that in D. acetoxidans acetate is oxidized to CO2 via the acetyl-CoA/carbon monoxide dehydrogenase (CODH) pathway [30] and all necessary genes required for this pathway have been annotated in the finished genome sequence. Interestingly, a core set of genes that is specific for this pathway shows the same arrangement in D. acetoxidans (Dtox_1269 to 1276) as in the distantly related homoacetogenic bacterium Moorella thermoacetica (cooC/acsE) [31]. A cluster of genes (Dtox_1697 to 1703) that is probably required for growth with butyrate as substrate could be also identified. It has been reported that acetate accumulates upon growth on butyrate and that acetate is only further metabolized to CO2 under conditions of carbon substrate limitation [2]. This could indicate that the acetyl-CoA/CODH pathway in this strain is only induced under conditions of energy limitation. For the utilization of primary alcohols several putative alcohol dehydrogenases may be used that are encoded at various sites in the genome of D. acetoxidans.

Strain 5575T exhibits a prolonged lag phase upon transfer from media with acetate or butyrate as carbon source to media supplied with other organic substrates [2]. Hence, the identification of additional growth substrates might have been hampered by requiring elongated incubation times of several weeks. This could explain why the utilization of lactate is discussed controversially in the literature. According to Widdel and Pfennig [1,2] this strain is unable to use lactate, whereas Pawłowska-Ćwięk and Pado have repeatedly postulated growth on lactate as sole carbon source [32]. The genome here reported encodes a putative D-lactate dehydrogenase gene (Dtox_0988), which is however only distantly related to genes encoding enzymes known to be involved in the respiration or fermentation of lactate. Hence, it is unclear if this enzyme could be involved in the utilization of lactate by D. acetoxidans. In our experiments strain 5575T did not show any visible growth on lactate after an incubation period of four weeks.

It was also stated that glucose, fructose, maltose and cellobiose are unsuitable electron donors for this species [2]. However, all necessary genes encoding enzymes of the Embden-Meyerhof-Parnas pathway for the conversion of sugars to pyruvate (glycolysis) were identified in the genome sequence. Hence, it is possible that this pathway is used only for the internal metabolism of carbohydrates and that a transport system for the efficient uptake of sugars is not expressed.

Autotrophic growth

Londry and Des Marais [17] reported that D. acetoxidans can grow autotrophically with H2 as the electron donor and CO2 as carbon source, which is contradictory to the original species description [1,2]. Genes for several subunits of a putative Fe-only hydrogenase (Dtox_0168, Dtox_0169 and Dtox_0172 to 0178) and a [NiFe]-hydrogenase (Dtox_0791 to 0796) were detected in the genome of D. acetoxidans, which would confirm the finding of H2 utilization in this species.

The acetyl-CoA/CODH pathway is fully reversible and it was shown that in D. autotrophicum it is used for both the cleavage and formation of acetyl-CoA [33]. Hence, Londry and Des Marais [17] proposed that D. acetoxidans uses the acetyl-CoA/CODH pathway for the fixation of CO2 under lithoautotrophic growth conditions. They reported that during growth on H2/CO2 and sulfate, small amounts of acetate were excreted, which would confirm that the reductive acetyl-CoA pathway is used as mechanism for CO2 assimilation.

Interestingly, a cluster of nitrogenase genes (Dtox_1023 to 1030) could be detected within the annotated genome sequence, so that D. acetoxidans likely has the capacity to use dinitrogen as nitrogen source. However, the fixation of molecular nitrogen has not been analyzed by laboratory experiments in this species so far.

Electron transport phosphorylation

The oxidation of carbon sources by dehydrogenases leads to the formation of reduced pyridine nucleotides that are most likely reoxidized in D. acetoxidans by a proton-translocating NADH dehydrogenase complex, which reduces menaquinones. The structure of the NADH dehydrogenase seems to be similar to complex I in the electron transport chain of E. coli and mitochondria. Most genes for this complex are located in a single operon (Dtox_1205 to 1215), but genes for the subunits E, F, and G are located elsewhere in the genome and often found in close proximity to genes involved in energy metabolism. Several genes encoding heterodisulfide reductases were annotated and also found close to genes involved in electron transport. Hence, it can be assumed that besides the NADH dehydrogenase complex, heterodisulfide reductases play a role in the generation of a proton gradient, as has been previously proposed for the homoacetogenic bacterium Moorella thermoacetica [31]. An established proton gradient could then be utilized by an ATP synthase of the F0F1-type, which is encoded in a single gene cluster (Dtox_4164 to 4172).

Besides genes involved in sulfate reduction no other genes encoding known enzymes for alternative pathways of anaerobic respiration were detected in the genome, so that in this species the utilization of electron acceptors seems to be restricted to oxidized sulfur species for sulfate reduction and CO2 for the synthesis of acetyl-CoA. So far, no homoacetogenic growth of D. acetoxidans with H2 or organic compounds as electron donor could be shown, so that apparently the reduction of CO2 is not coupled to the generation of energy in this species.

Defense against oxidative stress

Widdel and Pfennig reported in the original species description of D. acetoxidans an inhibition of growth in media that were not fully reduced [1], which would indicate a high sensitivity against oxygen. Most known sulfate-reducers tolerate exposure to oxygen for at least short intervals without any recognizable cellular damage. Aerobic respiration was identified as one principal mechanism for the detoxification of oxygen in cultures of Gram-negative sulfate-reducers [34]. Accordingly, quinol oxidases of the cytochrome bd type that are characterized by a high-affinity to oxygen were identified in several Gram-negative sulfate-reducers [35-38] and ‘D. reducens’ (this study). However, no genes encoding a potential terminal oxidase could be identified in the genome of D. acetoxidans. Only genes encoding enzymes representing a second line of defense against reactive oxygen species were identified, for example superoxide dismutase (Dtox_4195) and catalase (Dtox_1104).

Thus, a peculiarity of the D. acetoxidans metabolism could be its strategy against oxidative stress. In this species other reactions may be involved in the scavenging of oxygen, so that highly sensitive compounds within the cytoplasm are protected. A potential mechanism could be the chemical reaction of oxygen with ferrous iron or iron sulfides. It was shown that cells of D. acetoxidans produce hydroxamic siderophores (probably deferoxamine) and accumulate large amounts of ferrous sulfide (FeS) or pyrite (FeS2) in their cell wall [39]. Previously, it was demonstrated in vitro that freshly precipitated ferrous sulfide is highly effective in the protection of strictly anaerobic cells against oxygen [40]. On the other hand, it was reported that large amounts of sulfide (above 7 mM) produced during sulfate-reduction can inhibit growth of certain Desulfotomaculum species [41], so that ferrous iron could also prevent toxic effects of sulfide by precipitation at the cell exterior. Several genes encoding ferrous iron transport proteins as well as subunits of ABC-type transporters specific for the uptake of Fe3+ siderophores were annotated in the genome of D. acetoxidans, which emphasizes the importance of iron in the metabolism of this species.
