Jung-Hyun Lee, Jong Bhak and their colleagues report the whole-genome sequencing de novo assembly of a male minke whale genome, as well genome sequences three additional whales, fin whale, bottlenose dolphin finless porpoise. Their comparative analysis across cetaceans provides insights into adaptation to an aquatic lifestyle. The shift from terrestrial life by whales was substantial evolutionary event. Here we Our genomic identified expansion in lineage gene families associated with...
A Gram-negative, yellow-pigmented, halophilic bacterial strain US6-1 T , which degrades high-molecular-mass polycyclic aromatic hydrocarbons of two to five rings, was isolated from muddy sediment Ulsan Bay, Republic Korea. The 16S rRNA gene the isolate showed high sequence similarity Novosphingobium subarcticum (96·23 %) and Sphingopyxis alaskensis (96·18 %); however, formed a distinct phyletic line within genus . DNA–DNA relatedness between closest N. revealed that independent this species....
ABSTRACT Members of the genus Thermococcus , sulfur-reducing hyperthermophilic archaea, are ubiquitously present in various deep-sea hydrothermal vent systems and considered to play a significant role microbial consortia. We complete genome sequence feature analysis onnurineus NA1 isolated from area, which reveal clues its physiology. Based on results genomic analysis, T. possesses metabolic pathways for organotrophic growth peptides, amino acids, or sugars. More interesting was discovery...

Lower similarities were shown other members genus (94.6-95.4 %) and Porphyrobacter (94.5-95.2 %). Phylogenetic analysis with all family Erythrobacteraceae several Sphingomonadaceae revealed formed phyletic line [Erythrobacter] distinct Erythrobacteraceae....
The complete genome sequence of "Candidatus Puniceispirillum marinum" IMCC1322, the first cultured representative SAR116 clade in Alphaproteobacteria, is reported here. contains genes for proteorhodopsin, aerobic-type carbon monoxide dehydrogenase, dimethylsulfoniopropionate demethylase, and C(1) compound metabolism. information proposes group to be metabolic generalists ocean nutrient cycling.
Bacteria in the Desulfovibrionaceae family, which contribute to S element turnover as sulfate-reducing bacteria (SRB) and disproportionation of partially oxidized sulfoxy anions, have been extensively investigated since importance sulfur cycle emerged. Novel species belonging this taxon are frequently reported, because they exist various environments easy culture using established methods. Due rapid expansion taxon, correction reclassification conducted. The development high-throughput...
A marine bacterium, designated strain GW14-5(T), capable of degrading high-molecular-mass polycyclic aromatic hydrocarbons was isolated from the sediments Gwangyang Bay, Republic Korea, after enrichment culture for 2 years with a mixture benzo[a]pyrene and pyrene. Phylogenetic analysis based on 16S rRNA gene sequences indicated that isolate forms phyletic lineage is distinct seven known orders within 'Alphaproteobacteria'. sequence similarity GW14-5(T) to all recognized bacterial species not...
Two facultatively anaerobic mesophilic bacteria, strains MEBiC 07026 T and 08903 , were isolated from two different tidal flat sediments both showed approximately 92.2 % 16S rRNA gene sequence similarity with [ Cytophaga ] fermentans DSM 9555 . between the new isolates was 97.5 but levels of DNA–DNA relatedness 31.3–31.8 %. Phylogenetic analysis revealed that affiliated family Marinilabiliaceae in class Bacteroidia The dominant fatty acids branched-type or hydroxylated C 15 : 0 contained a...
The intertidal zone is an area located between the marine environment and terrestrial exposed to various stresses. To investigate mutualistic relationship hosts symbiotic micro-organisms inhabiting zone, strains 2305UL8-3 T 2305UL8-7 were isolated from Reishia bronni , a species living in of Ulleungdo Island, South Korea. Both are Gram-stain-negative, catalase- oxidase-positive facultatively anaerobic. Strains grow optimally at 30.0 °C 28.0–30.0 °C, respectively, under conditions pH 8.0 3.0...
Archaea thrive in extreme environments, exhibiting unique traits with significant biotechnological potential. In this study, we investigated whether Thermococcus onnurineus NA1 could stably integrate a large glycoside hydrolase (GH) gene cluster from T. pacificus P-4, enhancing β-linked polysaccharides degradation for hydrogen production. Among 35 genomes examined via OrthoFinder2 and OrthoVenn3, selecting Tpa-GH clusters as the target, cloned integrated into using fosmid-based system,...
A taxonomic study of a novel marine, heterotrophic, non-gliding, halotolerant and light-pink-pigmented bacterium was carried out using polyphasic approach. 16S rRNA gene sequence analysis revealed that strain KMM 6241 T is member the phylum Bacteroidetes. Strain formed cluster with genera Algoriphagus , Chimaereicella Hongiella similarities 94.0–98.2 %. ornithinivorans closest relative isolate. Comparative phenotypic, chemotaxonomic genotypic characteristics representatives many similar...
