Complete genome sequence of Deinococcus maricopensis type strain (LB-34T)

Deinococcus maricopensis (Rainey and da Costa 2005) is a member of the genus Deinococcus, which is comprised of 44 validly named species and is located within the deeply branching bacterial phylum Deinococcus Thermus. Strain LB-34T was isolated from a soil sample from the Sonoran Desert in Arizona. Various species of the genus Deinococcus are characterized by extreme radiation resistance, with D. maricopensis being resistant in excess of 10 kGy. 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.

Permanent draft genome sequence of Vibrio tubiashii strain NCIMB 1337 (ATCC19106).

Vibrio tubiashii NCIMB 1337 is a major and increasingly prevalent pathogen of bivalve mollusks, and shares a close phylogenetic relationship with both V. orientalis and V. coralliilyticus. It is a Gram-negative, curved rod-shaped bacterium, originally isolated from a moribund juvenile oyster, and is both oxidase and catalase positive. It is capable of growth under both aerobic and anaerobic conditions. Here we describe the features of this organism, together with the draft genome and annotation. The genome is 5,353,266 bp long, consisting of two chromosomes, and contains 4,864 protein-coding and 86 RNA genes.

Complete genome sequence of Bacteroides salanitronis type strain (BL78T)

Bacteroides salanitronis Lan et al. 2006 is a species of the genus Bacteroides, which belongs to the family Bacteroidaceae. The species is of interest because it was isolated from the gut of a chicken and the growing awareness that the anaerobic microflora of the cecum is of benefit for the host and may impact poultry farming. The 4,308,663 bp long genome consists of a 4.24 Mbp chromosome and three plasmids (6 kbp, 19 kbp, 40 kbp) containing 3,737 protein-coding and 101 RNA genes and is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Complete genome sequence of Cellulophaga lytica type strain (LIM-21T)

Cellulophaga lytica (Lewin 1969) Johansen et al. 1999 is the type species of the genus Cellulophaga, which belongs to the family Flavobacteriaceae within the phylum 'Bacteroidetes' and was isolated from marine beach mud in Limon, Costa Rica. The species is of biotechnological interest because its members produce a wide range of extracellular enzymes capable of degrading proteins and polysaccharides. After the genome sequence of Cellulophaga algicola this is the second completed genome sequence of a member of the genus Cellulophaga. The 3,765,936 bp long genome with its 3,303 protein-coding and 55 RNA genes consists of one circular chromosome and is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Complete genome sequence of Hirschia baltica type strain (IFAM 1418T)

The family Hyphomonadaceae within the Alphaproteobacteria is largely comprised of bacte- ria isolated from marine environments with striking morphologies and an unusual mode of cell growth. Here, we report the complete genome sequence Hirschia baltica, which is only the second a member of the Hyphomonadaceae with a published genome sequence. H. bal- tica is of special interest because it has a dimorphic life cycle and is a stalked, budding bacte- rium. The 3,455,622 bp long chromosome and 84,492 bp plasmid with a total of 3,222 pro- tein-coding and 44 RNA genes were sequenced as part of the DOE Joint Genome Institute Program CSP 2008.

Complete genome sequence of the halophilic and highly halotolerant Chromohalobacter salexigens type strain (1H11T)

Chromohalobacter salexigens is one of nine currently known species of the genus Chromoha- lobacter in the family Halomonadaceae. It is the most halotolerant of the so-called mod- erately halophilic bacteria currently known and, due to its strong euryhaline phenotype, it is an established model organism for prokaryotic osmoadaptation. C. salexigens strain 1H11T and Halomonas elongata are the first and the second members of the family Halomonada- ceae with a completely sequenced genome. The 3,696,649 bp long chromosome with a total of 3,319 protein-coding and 93 RNA genes was sequenced as part of the DOE Joint Genome Institute Program DOEM 2004.

Complete genome sequence of Polynucleobacter necessarius subsp. asymbioticus type strain (QLW-P1DMWA-1T)

Polynucleobacter necessarius subsp. asymbioticus Hahn et al. 2009 is one of currently two subspecies of P. necessarius. While P. necessarius subsp. asymbioticus is a free-living bacterium, the closely related second subspecies, P. necessarius subsp. necessarius is an obligate endosymbiont living in the cytoplasm of freshwater ciliates of the genus Euplotes aediculatus. The two P. necessarius subspecies were the closest thus far reported phylogenetic neighbors that differ in their lifestyle as obligately free-living vs. obligate endosymbiontic, and they are the only members of the genus Polynucleobacter with completely sequenced genomes. The genome-sequenced strain represents a group of closely related strains not distinguishable by 16S rRNA, 16S-23S ITS or glnA sequences, which is persistent in the home habitat of the strain and frequently contributes > 10% of total bacterial numbers in water samples of the habitat. The 2,159,490 bp long chromosome with a total of 2,088 protein-coding and 48 RNA genes was sequenced as part of the DOE Joint Genome Institute Community Sequencing Program 2006.

Complete genome sequence of Halopiger xanaduensis type strain (SH6T)

Halopiger xanaduensis is the type species of the genus Halopiger and belongs to the euryarchaeal family Halobacteriaceae. H. xanaduensis strain SH-6, which is designated as the type strain, was isolated from the sediment of a salt lake in Inner Mongolia, Lake Shangmatala. Like other members of the family Halobacteriaceae, it is an extreme halophile requiring at least 2.5 M salt for growth. We report here the sequencing and annotation of the 4,355,268 bp genome, which includes one chromosome and three plasmids. This genome is part of a Joint Genome Institute (JGI) Community Sequencing Program (CSP) project to sequence diverse haloarchaeal genomes.

Complete genome sequence of the rapeseed plant-growth promoting Serratia plymuthica strain AS9

Serratia plymuthica are plant-associated, plant beneficial species belonging to the family Enterobacteriaceae. The members of the genus Serratia are ubiquitous in nature and their life style varies from endophytic to free-living. S. plymuthica AS9 is of special interest for its ability to inhibit fungal pathogens of rapeseed and to promote plant growth. The genome of S. plymuthica AS9 comprises a 5,442,880 bp long circular chromosome that consists of 4,952 protein-coding genes, 87 tRNA genes and 7 rRNA operons. This genome is part of the project entitled Genomics of four rapeseed plant growth promoting bacteria with antagonistic effect on plant pathogens awarded through the 2010 DOE-JGI Community Sequencing Program (CSP2010).

Complete genome sequence of Dehalogenimonas lykanthroporepellens type strain (BL-DC-9T) and comparison to Dehalococcoides strains

Dehalogenimonas lykanthroporepellens is the type species of the genus Dehalogenimonas, which belongs to a deeply branching lineage within the phylum Chloroflexi. This strictly anaerobic, mesophilic, non spore forming, Gram negative staining bacterium was first isolated from chlorinated solvent contaminated groundwater at a Superfund site located near Baton Rouge, Louisiana, USA. D. lykanthroporepellens was of interest for genome sequencing for two reasons: (a) its unusual ability to couple growth with reductive dechlorination of environmentally important polychlorinated aliphatic alkanes and (b) its phylogenetic position distant from previously sequenced bacteria. The 1,686,510 bp circular chromosome of strain BL-DC-9{sup T} contains 1,720 predicted protein coding genes, 47 tRNA genes, a single large subunit rRNA (23S-5S) locus, and a single, orphan, small unit rRNA (16S) locus.
