Pseudomonas azotifigens sp. nov., a novel nitrogen-fixing bacterium isolated from a compost pile.

A nitrogen-fixing bacterium, designated strain 6H33b(T), was isolated from a compost pile in Japan. The nitrogenase activity of this strain was detected based on its acetylene-reducing activity under low oxygen concentrations (2-4%). An analysis of the genes responsible for nitrogen fixation in this strain, nifH and nifD, indicated a close relationship to those of Pseudomonas stutzeri A15 (A150...

Pseudacidovorax intermedius gen. nov., sp. nov., a novel nitrogen-fixing betaproteobacterium isolated from soil.

A Gram-negative, short rod-shaped, nitrogen-fixing bacterium (CC-21(T)) was isolated from a soil sample collected from the regional agricultural research station in Kaohsiung County (Taiwan). Using 16S rRNA gene sequence analysis, it could be clearly demonstrated that this isolate was novel: it showed <97 % similarity to species of the genera Acidovorax, Alicycliphilus, Giesbergeria, Simplicisp...

Bradyrhizobium ottawaense sp. nov., a symbiotic nitrogen fixing bacterium from root nodules of soybeans in Canada

Sixteen strains of symbiotic bacteria from root nodules of Glycine max grown in Ottawa, Canada, were previously characterized and placed in a novel group within the genus Bradyrhizobium. To verify their taxonomic status, these strains were further characterized using a polyphasic approach. All strains possessed identical 16S rRNA gene sequences that were 99.79 % similar to the closest relative,...

Celerinatantimonas diazotrophica gen. nov., sp. nov., a nitrogen-fixing bacterium representing a new family in the Gammaproteobacteria, Celerinatantimonadaceae fam. nov.

Five strains representing a novel family within the Gammaproteobacteria were isolated from the estuarine grasses Spartina alterniflora and Juncus roemerianus. All strains were facultatively anaerobic, Gram-negative, short, motile, polar monotrichous rods that were mesophilic, oxidase-negative, catalase-positive, had DNA G+C contents of 41.5-44.4 mol% and required seawater salts or NaCl. Growth ...

Pontibacter diazotrophicus sp. nov., a Novel Nitrogen-Fixing Bacterium of the Family Cytophagaceae

Few diazotrophs have been found to belong to the family Cytophagaceae so far. In the present study, a Gram-negative, rod-shaped bacterium that forms red colonies, was isolated from sands of the Takalamakan desert. It was designated H4XT. Phylogenetic and biochemical analysis indicated that the isolate is a new species of the genus Pontibacter. The 16S rRNA gene of H4XT displays 94.2-96.8% seque...
