We report here the genome sequences of three Aquimarina megaterium strains isolated from the octocoral Eunicella labiata . We reveal a coding potential for versatile carbon metabolism and biosynthesis of natural products belonging to the polyketide, nonribosomal peptide, and terpene compound classes.
Here, we report the draft genome sequence of the siderophilic cyanobacterium Fischerella thermalis JSC-11, which was isolated from an iron-depositing hot spring. JSC-11 has bioremediation potential because it is capable of both extracellular absorption and intracellular mineralization of colloidal iron. This genomic information will facilitate the exploration of JSC-11 for bioremediation.
We report the genome sequence of a polyethylene-degrading bacterial strain identified as Stenotrophomonas maltophilia strain PE591, which was isolated from plastic debris found in savanna soil. The genome was assembled in 16 scaffolds with a length of 4,751,236 bp, a GC content of 66.5%, and 4,432 predicted genes.
The genome sequences of three extremely thermophilic, lignocellulolytic Caldicellulosiruptor species were closed, improving previously reported multiple-contig assemblies. All 14 classified Caldicellulosiruptor spp. now have closed genomes. Genome closure will enhance bioinformatic analysis of the species, including identification of carbohydrate-active enzymes (CAZymes) and comparison against other Caldicellulosiruptor species and lignocellulolytic microorganisms.
We report the complete genome sequence of Methanospirillum hungatei strain GP1 (DSM 1101). Strain GP1 oxidizes H 2 , formate, and secondary alcohols as the substrates for methanogenesis. Members of the genus are model organisms used to study syntrophic growth with bacterial partners, but secondary alcohol metabolism remains poorly studied.
Here, we report the complete genome sequence of the tetrachloroethene-to-trichloroethene dechlorinator Sulfurospirillum sp. strain ACS TCE . The genome consists of a 38.05-kb circular plasmid and a 2.69-Mb circular chromosome, which encodes 3 identical reductive dehalogenases with 91.47% amino acid identity to the PceA of Sulfurospirillum multivorans strain DSM 12446.
Here, we report the genome sequence of Tenacibaculum mesophilum strain ECR, which was isolated from the river/ocean interface at Trunk River, Falmouth, Massachusetts, USA. The isolation and sequencing were performed as part of the 2016 and 2018 Microbial Diversity courses at the Marine Biological Laboratory in Woods Hole, Massachusetts, USA.
This study describes the whole genome sequence of Dolosicoccus paucivorans 2991-95 (DSM 15742) isolated from human blood in Cleveland, Ohio. The genome length is approximately 1.8 Mbp with 107 contigs and a G + C content of 37.91%. Annotation identified 1,752 coding genes and multiple virulence factors.
This narrative was used for a draft genome of a Larkinella species. This genus contains 9 identified species, of which only 5 have genome sequence data. This specimen was collected from a root sample of an eastern cottonwood (Populus deltoides) from a field site in Bellville, Georgia.
As a leading cause of bacterial-derived gastroenteritis worldwide, Campylobacter jejuni has a significant impact on human health in both the developed and developing worlds. Despite its prevalence as a human pathogen, the source of these infections remains poorly understood due to the mutation frequency of the organism and past limitations of whole genome analysis. Recent advances in both whole genome sequencing and computational methods have allowed for the high-resolution analysis of intraspecies diversity, leading multiple groups to postulate that these approaches may be used to identify the sources of Campylobacter jejuni infection. To address this hypothesis, our group conducted a regionally and temporally restricted sampling of agricultural and environmental Campylobacter sources and compared isolated C. jejuni genomes to those that caused human infections in the same region during the same time period. Through a network analysis comparing genomes from various sources, we found that human C. jejuni isolates clustered with those isolated from cattle and chickens, indicating these as potential sources of human infection in the region.
Here, we report the annotated genome sequence for a heterokont alga from the class Xanthophyceae. This high-biomass-producing strain, Tribonema minus UTEX B 3156, was isolated from a wastewater treatment plant in California. It is stable in outdoor raceway ponds and is a promising industrial feedstock for biofuels and bioproducts.
ABSTRACT We report the draft genome sequence of a novel species, Exiguobacterium sp., isolated from a freshly harvested and untreated cantaloupe in North Carolina. The strain Exiguobacterium wild type exhibited inhibitory activity against the foodborne pathogen Listeria monocytogenes , including strains of diverse serotypes and genotypes, both on agar media and in biofilms.
Here, we present the draft genome sequence of a novel species of the genus Singulisphaera (phylum Planctomycetes , family Isosphaeraceae ) isolated from soil. Singulisphaera sp. strain GP187 has a relatively large mobilome and numerous novel genes that may contribute to the production of bioactive molecules.
Cupriavidus basilensis SRS was isolated from stream sediments from the Savannah River Site in South Carolina. Here, we report the draft genome sequence and annotation of Cupriavidus basilensis SRS. The genome contains 8,918,236 bp and 7,916 predicted protein-coding genes, with a total G+C content of 65.2%.
This Narrative was used for a complete genome sequence of a new strain of Terriglobus albidus. It is a heterotrophic bacterium associated with the rhizophere of the eastern cottonwood tree (Populus deltoides).
Pseudomonas strains DVZ6 and DVZ24 were isolated from a sediment trap incubated in an 129 I plume at the Hanford Site (Washington State, USA). Whole-genome sequencing of the strains revealed that both genomes are 5.77 Mb in size, with a G + C content of 64.75%.
Bacillus cereus strain CPT56D-587-MTF was isolated from nitrate- and toxic metal-contaminated subsurface sediment at the Oak Ridge Reservation (ORR) (Oak Ridge, TN, USA). Here, we report the complete genome sequence of this strain to provide genomic insight into its strategies for survival at this mixed-waste site.
Pseudenhygromyxa WMMC2535, a representative of the myxobacteria (family Nannocystaceae ), was isolated from a ragged sea hare in the Florida Keys, and its genome was sequenced using PacBio technology. The WMMC2535 genome sequence is the first of this genus and validates the notion that myxobacteria represent outstanding sources of structurally diverse natural products.
