A bacterial strain named IMCC1877T was obtained from surface seawater collected near the coast of Deokjeok island (Yellow Sea), using a standard dilution-plating method. The strain was Gram-negative, chemoheterotrophic and facultatively anaerobic, requiring NaCl, and cells were motile rods with a single polar flagellum. Colonies on marine agar were very small (average diameter 0.1 mm). Based on 16S rRNA gene sequences, the most closely related species to strain IMCC1877T was Marinobacterium stanieri (93.7 % sequence similarity to the type strain). Phylogenetic analyses based on 16S rRNA gene sequences showed that this marine isolate belonged to the order Oceanospirillales and formed an independent phyletic line within the clade forming the genus Marinobacterium. The DNA G+C content of the strain was 60.7 mol% and the predominant constituents of the cellular fatty acids were C18 : 1
ω7c (36.6 %), C16 : 1
ω7c and/or iso-C15 : 0 2-OH (26.7 %) and C16 : 0 (24.3 %). Based on the taxonomic data, only a distant relationship could be established between strain IMCC1877T and other Marinobacterium species; the strain therefore represents a novel species of the genus Marinobacterium, for which the name Marinobacterium litorale sp. nov. is proposed. The type strain is IMCC1877T (=KCTC 12756T=LMG 23872T).read more

Life in the slow lane; biogeochemistry of biodegraded petroleum containing reservoirs and implications for energy recovery and carbon management
TL;DR: A synthesis of new and existing microbiological, geochemical, and biogeochemical data is presented that proposes that the salinity of reservoir formation waters exerts a key control on the occurrence of biodegraded heavy oil reservoirs and introduces the concept of palaeopickling.

TL;DR: Investigation of crude oil degradation under sulphate-reducing conditions was investigated in microcosms, amended with North Sea crude oil and inoculated with estuarine sediment from the River Tyne, UK, suggesting that other groups of organisms in addition to conventional sulphatesporomusa, Firmicutes, Proteobacteria andSRM play a role in the anaerobic degradation of crudeOil in some sulphATE-containing environments.

TL;DR: It was shown that changes, like a decrease in temperature, cause a distinctive shift in these communities, and the fact that changes in the community can be linked to changes in their environment might indicate that these tools can be used for the monitoring of changing conditions in oil reservoirs upon, for example, water flooding.

TL;DR: The first genomic sequences obtained for the carrot-associated CLso were obtained from carrot psyllids (Trioza apicalis) harboring CLso and revealed that the genome organization differs between these haplotypes, due to large inversions and other recombinations.

A simple method for estimating evolutionary rates of base substitutions through comparative studies of nucleotide sequences.
TL;DR: Some examples were worked out using reported globin sequences to show that synonymous substitutions occur at much higher rates than amino acid-altering substitutions in evolution.

TL;DR: A computationally feasible method for finding such maximum likelihood estimates is developed, and a computer program is available that allows the testing of hypotheses about the constancy of evolutionary rates by likelihood ratio tests.
