© Standards in Genomic Sciences, 2014. Thermotoga thermarum Windberger et al. 1989 is a member to the genomically well charac-terized genus Thermotoga in the phylum 'Thermotogae'. T. thermarum is of interest for its origin from a continental solfataric spring vs. predominantly marine oil reservoirs of other members of the genus. The genome of strain LA3T also provides fresh data for the phylogenomic positioning of the (hyper-)thermophilic bacteria. T. thermarum strain LA3T is the fourth sequenced genome of a type strain from the genus Thermotoga, and the sixth in the family Thermotogaceae to be formally described in a publication. Phylogenetic analyses do not reveal significant discrepancies between the current classification of the group, 16S rRNA gene data and whole-genome sequences. Nevertheless, T. thermarum significantly dif-fers from other Thermotoga species regarding its iron-sulfur cluster synthesis, as it contains only a minimal set of the necessary proteins. Here we describe the features of this organism, together with the complete genome sequence and annotation.

Strain DLT (= DSM 2154 = ATCC 23193 = NCIMB 8452) is the type strain of the species Desulfotomaculum ruminis [1], one out of current-ly 30 species with validly published names in the paraphyletic genus Desulfotomaculum [2,3]. Strain DLT was initially isolated by G. S. Coleman in the 1950s from the rumen of hay-fed sheep [4]. Dissimilatory reduction of sulfate to sulfide in the rumen was first demonstrated by Lewis [5], who dosed fistulated sheep with sulfate and deter-mined the amount of sulfide produced. As high amounts of sulfide may be toxic to animals, bacte-rial sulfate-reduction in ruminants was a concern due to the presence of sulfate in grass and hay. D. ruminis represented the first pure culture of a sul-fate-reducing bacterium isolated from the rumen. The genus name was derived from the Latin words 'de', from, ‘sulfur’, sulfur, and 'tomaculum', a kind of sausage, meaning 'a sausage-shaped sul-fate reducer' [2,6]. The species epithet is derived from the Latin word 'rumen', throat, first stomach (rumen) of a ruminant, meaning of a rumen [1,2]. Here, we present a summary classification and a set of features for D. ruminis strain DLT, together with the description of the complete genomic se-quencing and annotation. The complete genome sequence of strain DLT will provide valuable in-formation for defining a more adequate descrip-tion of the currently paraphyletic genus Desulfotomaculum

Fluviicola taffensis O'Sullivan et al. 2005 belongs to the monotypic genus Fluviicola within the family Cryomorphaceae. The species is of interest because of its isolated phylogenetic location in the genome-sequenced fraction of the tree of life. Strain RW262(T) forms a monophyletic lineage with uncultivated bacteria represented in freshwater 16S rRNA gene libraries. A similar phylogenetic differentiation occurs between freshwater and marine bacteria in the family Flavobacteriaceae, a sister family to Cryomorphaceae. Most remarkable is the inability of this freshwater bacterium to grow in the presence of Na(+) ions. All other genera in the family Cryomorphaceae are from marine habitats and have an absolute requirement for Na(+) ions or natural sea water. F. taffensis is the first member of the family Cryomorphaceae with a completely sequenced and publicly available genome.

Even though the genomes of three Deinococcus species, D. radiodurans, D. geothermalis and D. deserti, have already been published, no special physiological characteristic is currently known that is unique to this group. It is therefore of special interest to analyze the genomes of additional species of the genus Deinococcus to better understand how these species adapted to gamma- or UV ionizing-radiation. The 3,498,530 bp long genome of D. maricopensis with its 3,301 protein-coding and 66 RNA genes consists of one circular chromosome and is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Desulfurococcus mucosus Zillig and Stetter 1983 is the type species of the genus Desulfurococcus, which belongs to the crenarchaeal family Desulfurococcaceae. The species is of interest because of its position in the tree of life, its ability for sulfur respiration, and several biotechnologically relevant thermostable and thermoactive extracellular enzymes. This is the third completed genome sequence of a member of the genus Desulfurococcus and already the 8(th) sequence from a member the family Desulfurococcaceae. The 1,314,639 bp long genome with its 1,371 protein-coding and 50 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Bacteroides coprosuis Whitehead et al. 2005 belongs to the genus Bacteroides, which is a member of the family Bacteroidaceae. Members of the genus Bacteroides in general are known as beneficial protectors of animal guts against pathogenic microorganisms, and as contributors to the degradation of complex molecules such as polysaccharides. B. coprosuis itself was isolated from a manure storage pit of a swine facility, but has not yet been found in an animal host. The species is of interest solely because of its isolated phylogenetic location. The genome of B. coprosuis is already the 5(th) sequenced type strain genome from the genus Bacteroides. The 2,991,798 bp long genome with its 2,461 protein-coding and 78 RNA genes and is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Stackebrandtia nassauensis Labeda and Kroppenstedt (2005) is the type species of the genus Stackebrandtia, and a member of the actinobacterial family Glycomycetaceae. Stackebrandtia currently contains two species, which are differentiated from Glycomyces spp. by cellular fatty acid and menaquinone composition. Strain LLR-40K-21(T) is Gram-positive, aerobic, and nonmotile, with a branched substrate mycelium and on some media an aerial mycelium. The strain was originally isolated from a soil sample collected from a road side in Nassau, Bahamas. Here we describe the features of this organism, together with the complete genome sequence and annotation. This is the first complete genome sequence of the actinobacterial suborder Glycomycineae. The 6,841,557 bp long single replicon genome with its 6487 protein-coding and 53 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

Sulfurospirillum deleyianum Schumacher et al. 1993 is the type species of the genus Sulfurospirillum. S. deleyianum is a model organism for studying sulfur reduction and dissimilatory nitrate reduction as an energy source for growth. Also, it is a prominent model organism for studying the structural and functional characteristics of cytochrome c nitrite reductase. Here, we describe the features of this organism, together with the complete genome sequence and annotation. This is the first completed genome sequence of the genus Sulfurospirillum. The 2,306,351 bp long genome with its 2,291 protein-coding and 52 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

Intrasporangium calvum Kalakoutskii et al. 1967 is the type species of the genus Intrasporangium, which belongs to the actinobacterial family Intrasporangiaceae. The species is a Gram-positive bacterium that forms a branching mycelium, which tends to break into irregular fragments. The mycelium of this strain may bear intercalary vesicles but does not contain spores. The strain described in this study is an airborne organism that was isolated from a school dining room in 1967. One particularly interesting feature of I. calvum is that the type of its menaquinone is different from all other representatives of the family Intrasporangiaceae. This is the first completed genome sequence from a member of the genus Intrasporangium and also the first sequence from the family Intrasporangiaceae. The 4,024,382 bp long genome with its 3,653 protein-coding and 57 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Thermosediminibacter oceani (Lee et al. 2006) is the type species of the genus Thermosediminibacter in the family Thermoanaerobacteraceae. The anaerobic, barophilic, chemoorganotrophic thermophile is characterized by straight to curved Gram-negative rods. The strain described in this study was isolated from a core sample of deep sea sediments of the Peruvian high productivity upwelling system. This is the first completed genome sequence of a member of the genus Thermosediminibacter and the seventh genome sequence in the family Thermoanaerobacteraceae. The 2,280,035 bp long genome with its 2,285 protein-coding and 63 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Halorhabdus utahensis Wainø et al. 2000 is the type species of the genus, which is of phylogenetic interest because of its location on one of the deepest branches within the very extensive euryarchaeal family Halobacteriaceae. H. utahensis is a free-living, motile, rod shaped to pleomorphic, Gram-negative archaeon, which was originally isolated from a sediment sample collected from the southern arm of Great Salt Lake, Utah, USA. When grown on appropriate media, H. utahensis can form polyhydroxybutyrate (PHB). Here we describe the features of this organism, together with the complete genome sequence, and annotation. This is the first complete genome sequence of the a member of halobacterial genus Halorhabdus, and the 3,116,795 bp long single replicon genome with its 3027 protein-coding and 48 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

Denitrovibrio acetiphilus Myhr and Torsvik 2000 is the type species of the genus Denitrovibrio in the bacterial family Deferribacteraceae. It is of phylogenetic interest because there are only six genera described in the family Deferribacteraceae. D. acetiphilus was isolated as a representative of a population reducing nitrate to ammonia in a laboratory column simulating the conditions in off-shore oil recovery fields. When nitrate was added to this column undesirable hydrogen sulfide production was stopped because the sulfate reducing populations were superseded by these nitrate reducing bacteria. Here we describe the features of this marine, mesophilic, obligately anaerobic organism respiring by nitrate reduction, together with the complete genome sequence, and annotation. This is the second complete genome sequence of the order Deferribacterales and the class Deferribacteres, which is the sole class in the phylum Deferribacteres. The 3,222,077 bp genome with its 3,034 protein-coding and 51 RNA genes is part of the Genomic Encyclopedia of Bacteria and Archaea project.

Nocardiopsis dassonvillei (Brocq-Rousseau 1904) Meyer 1976 is the type species of the genus Nocardiopsis, which in turn is the type genus of the family Nocardiopsaceae. This species is of interest because of its ecological versatility. Members of N. dassonvillei have been isolated from a large variety of natural habitats such as soil and marine sediments, from different plant and animal materials as well as from human patients. Moreover, representatives of the genus Nocardiopsis participate actively in biopolymer degradation. This is the first complete genome sequence in the family Nocardiopsaceae. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 6,543,312 bp long genome consist of a 5.77 Mbp chromosome and a 0.78 Mbp plasmid and with its 5,570 protein-coding and 77 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.
