We report here the complete genome sequence of Pseudomonas sp. strain NC02, isolated from soil in eastern Massachusetts. We assembled PacBio reads into a single closed contig with 132× mean coverage and then polished this contig using Illumina MiSeq reads, yielding a 6,890,566-bp sequence with 61.1% GC content.

We report here the complete genome sequence of Escherichia coli strain ML35. We assembled PacBio reads into a single closed contig with 169× mean coverage and then polished this contig using Illumina MiSeq reads, yielding a 4,918,774-bp sequence with 50.8% GC content. Copyright © 2018 Casale et al.
Thermoanaerobacterium sp. strain RBIITD was isolated from contaminated rich growth medium at 55°C in an anaerobic chamber. It primarily produces butyrate as a fermentation product from plant biomass-derived sugars. The whole-genome sequence of the strain is 3.4 Mbp, with 3,444 genes and 32.48% GC content.
Alternaria brassicicola causes dark spot (or black spot) disease, which is one of the most common and destructive fungal diseases of Brassicaceae spp. worldwide. Here, we report the draft genome sequence of strain Abra43. The assembly comprises 29 scaffolds, with an N50 value of 2.1 Mb. The assembled genome was 31,036,461 bp in length, with a G+C content of 50.85%.
Bacillus caldolyticus NEB414 is the original source strain for the restriction enzyme BclI. Its complete sequence and full methylome were determined using single-molecule real-time sequencing. Copyright © 2018 Fomenkov et al.
We report here the complete genome sequence of Streptococcus thermophilus DGCC 7710. S. thermophilus is widely used in industrial dairy production.
As a part of the ELIXIR-EXCELERATE efforts in capacity building, we present here 10 steps to facilitate researchers getting started in genome assembly and genome annotation. The guidelines given are broadly applicable, intended to be stable over time, and cover all aspects from start to finish of a general assembly and annotation project. Intrinsic properties of genomes are discussed, as is the importance of using high quality DNA. Different sequencing technologies and generally applicable workflows for genome assembly are also detailed. We cover structural and functional annotation and encourage readers to also annotate transposable elements, something that is often omitted from annotation workflows. The importance of data management is stressed, and we give advice on where to submit data and how to make your results Findable, Accessible, Interoperable, and Reusable (FAIR).
Many bacteria in the environment have adopted to the presence of toxic heavy metals. Here we present the complete genome sequence of a heavy metal resistant bacterium, Maribacter cobaltidurans B1T (=CGMCC 1.15508T=KCTC 52882T=MCCC 1K03318T), which was isolated from a deep-sea sediment sample collected from the South Atlantic Ocean. Strain B1T is able to resist high concentrations of Co2+ (10.0mM) in Marine Agar 2216. The genome of strain B1T comprises 4,639,957bp in a circular chromosome with G+C content of 39.7mol%. Resistance to Co2+ is mainly based on efflux system in the genome of stain B1T, including czcCBA operons, czcD genes, corC genes, etc. Comparing with the closely related species M. orientalis DSM 16471T, the genome of B1T harbors twenty more copies of genes in czcCBA operon and two copies of the czcD genes related to Co2+ efflux. The function of these genes may contribute to the high level of cobalt resistance, revealing its potential application in biotechnological industry.
Halomonas aestuarii Hb3, a moderately halophilic bacterium belonging to the class Gammaproteobacteria, was isolated from a tidal flat. Herein, we report the complete genome sequence of its strain Hb3. Its size is estimated at 3.54Mbp with a mean G+C content of 67.9%. The genome includes 3238 open reading frames, 65 transfer RNAs, and four ribosomal RNA gene operons. Genes related to the degradation of monoaromatic compounds, detoxification of arsenic, and production of polymers were identified. These features indicate that this strain may be important for ecological and industrial application.
Granulosicoccus, the only genus of the family Granulosicoccaceae, occupies a distinct phylogenetic position within the order Chromatiales of the Gammaproteobacteria. The genus has been found in various marine regions, especially associated with diverse marine macroalgae. No genomes have been reported for the genus Granulosicoccus thus far, hampering studies on physiology and lifestyles of this genus. Here we report the complete genome sequence of strain IMCC3135T, the type strain of Granulosicoccus antarcticus isolated from Antarctic coastal seawater. The genome was 7.78Mbp long and harbored many genes involved in sulfur metabolism. In particular, a gene for dimethylsulfoniopropionate (DMSP) demethylase was found in the genome, rendering strain IMCC3135T one of the few marine gammaproteobacteria equipped with the potential for DMSP demethylation.
We present the genome sequence of Kushneria marisflavi KCCM 80003T isolated from Yellow Sea in Korea. The complete genome of KCCM 80003T consisted of a single, circular chromosome of 3,667,185bp, with an average G+C content of 59.05%, and 3287 coding sequences, 12 rRNAs, and 66 tRNAs. Kushneria marisflavi KCCM 80003T, belonging to the family Halomonadaceae, exhibited resistance to high salt concentrations and possessed potassium metabolism- or osmotic stress-related coding sequences, including potassium homeostasis, ectoine biosynthesis and regulation, choline and betaine uptake, and betaine biosynthesis features in the genome. These results provide a basis for understanding resistance strategies to osmotic stress at the genetic level and accordingly have implications for genetic engineering and biotechnology.
