Partial genome sequence of Thioalkalivibrio thiocyanodenitrificans ARhD 1(T), a chemolithoautotrophic haloalkaliphilic sulfur-oxidizing bacterium capable of complete denitrification

Thioalkalivibrio thiocyanodenitrificans strain ARhD 1(T) is a motile, Gram-negative bacterium isolated from soda lakes that belongs to the Gammaproteobacteria. It derives energy for growth and carbon fixation from the oxidation of sulfur compounds, most notably thiocyanate, and so is a chemolithoautotroph. It is capable of complete denitrification under anaerobic conditions. The draft genome sequence consists… [Read More]

Impact of library preparation protocols and template quantity on the metagenomic reconstruction of a mock microbial community

BACKGROUND: The rapid development of sequencing technologies has provided access to environments that were either once thought inhospitable to life altogether or that contain too few cells to be analyzed using genomics approaches. While 16S rRNA gene microbial community sequencing has revolutionized our understanding of community composition and diversity over time and space, it only… [Read More]

Complete genome sequence of Geobacillus thermoglucosidasius C56-YS93, a novel biomass degrader isolated from obsidian hot spring in Yellowstone National Park

Geobacillus thermoglucosidasius C56-YS93 was one of several thermophilic organisms isolated from Obsidian Hot Spring, Yellowstone National Park, Montana, USA under permit from the National Park Service. Comparison of 16 S rRNA sequences confirmed the classification of the strain as a G. thermoglucosidasius species. The genome was sequenced, assembled, and annotated by the DOE Joint Genome… [Read More]

Complete Genome Sequence of Methanosphaerula palustris E1-9CT, a Hydrogenotrophic Methanogen Isolated from a Minerotrophic Fen Peatland

Here, we report the complete genome sequence (2.92 Mb) of Methanosphaerula palustris E1-9C(T), a methanogen isolated from a minerotrophic fen. This is the first genome report of the Methanosphaerula genus, within the Methanoregulaceae family, in the Methanomicrobiales order. E1-9C(T) relatives are found in a wide range of ecological and geographical settings. [Read More]

High-quality draft genome sequence of Gracilimonas tropica CL-CB462(T) (DSM 19535(T)), isolated from a Synechococcus culture

Gracilimonas tropica Choi et al. 2009 is a member of order Sphingobacteriales, class Sphingobacteriia. Three species of the genus Gracilimonas have been isolated from marine seawater or a salt mine and showed extremely halotolerant and mesophilic features, although close relatives are extremely halophilic or thermophilic. The type strain of the type species of Gracilimonas, G…. [Read More]

Plant compartment and biogeography affect microbiome composition in cultivated and native Agave species

Desert plants are hypothesized to survive the environmental stress inherent to these regions in part thanks to symbioses with microorganisms, and yet these microbial species, the communities they form, and the forces that influence them are poorly understood. Here we report the first comprehensive investigation of the microbial communities associated with species of Agave, which… [Read More]

Enhanced degradation of softwood versus hardwood by the white-rot fungus Pycnoporus coccineus

BACKGROUND: White-rot basidiomycete fungi are potent degraders of plant biomass, with the ability to mineralize all lignocellulose components. Recent comparative genomics studies showed that these fungi use a wide diversity of enzymes for wood degradation. Deeper functional analyses are however necessary to understand the enzymatic mechanisms leading to lignocellulose breakdown. The Polyporale fungus Pycnoporus coccineus… [Read More]

High-quality permanent draft genome sequence of the Mimosa asperata – nodulating Cupriavidus sp. strain AMP6

Cupriavidus sp. strain AMP6 is an aerobic, motile, Gram-negative, non-spore-forming rod that was isolated from a root nodule of Mimosa asperata collected in Santa Ana National Wildlife Refuge, Texas, in 2005. Mimosa asperata is the only legume described so far to exclusively associates with Cupriavidus symbionts. Moreover, strain AMP6 represents an early-diverging lineage within the… [Read More]

High-quality permanent draft genome sequence of the Lebeckia ambigua-nodulating Burkholderia sp. strain WSM4176

Burkholderia sp. strain WSM4176 is an aerobic, motile, Gram-negative, non-spore-forming rod that was isolated from an effective N2-fixing root nodule of Lebeckia ambigua collected in Nieuwoudtville, Western Cape of South Africa, in October 2007. This plant persists in infertile, acidic and deep sandy soils, and is therefore an ideal candidate for a perennial based agriculture… [Read More]
