Genome sequences for six Rhodanobacter strains, isolated from soils and the terrestrial subsurface, with variable denitrification capabilities.
نویسندگان
چکیده
We report the first genome sequences for six strains of Rhodanobacter species isolated from a variety of soil and subsurface environments. Three of these strains are capable of complete denitrification and three others are not. However, all six strains contain most of the genes required for the respiration of nitrate to gaseous nitrogen. The nondenitrifying members of the genus lack only the gene for nitrate reduction, the first step in the full denitrification pathway. The data suggest that the environmental role of bacteria from the genus Rhodanobacter should be reevaluated.

Denitrifying bacteria isolated from terrestrial subsurface sediments exposed to mixed-waste contamination.
In terrestrial subsurface environments where nitrate is a critical groundwater contaminant, few cultivated representatives are available to verify the metabolism of organisms that catalyze denitrification. In this study, five species of denitrifying bacteria from three phyla were isolated from subsurface sediments exposed to metal radionuclide and nitrate contamination as part of the U.S. Depar...
متن کاملRhodanobacter denitrificans sp. nov., isolated from nitrate-rich zones of a contaminated aquifer.
Bacterial strains 2APBS1(T) and 116-2 were isolated from the subsurface of a nuclear legacy waste site where the sediments are co-contaminated with large amounts of acids, nitrate, metal radionuclides and other heavy metals. A combination of physiological and genetic assays indicated that these strains represent the first member of the genus Rhodanobacter shown to be capable of complete denitri...
متن کاملProfile of Eight Prophage Sequences Present in the Genomes of Different Acinetobacter baumannii Strains
ABSTRACT Background and Objective: Prophage sequences are major contributors to interstrain variations within the same bacterial species. Acinetobacter baumannii is a gram-negative bacterium that causes a wide range of nosocomial infections, especially in intensive care unit inpatients. Prophage sequences constitute a considerable proporti...
متن کاملDraft Genome Sequences of Six Vibrio diazotrophicus Strains Isolated from Deep Subsurface Sediments of the Baltic Sea
We present here the draft genome sequences of six Vibrio diazotrophicus strains, which were isolated from deep subseafloor sediments of the Baltic Sea. The genomic sequences contained several virulence and antibiotic resistance genes. These genome sequences provide insights into the genetic composition and evolution of the genus Vibrio in marine environments.
