Bradyrhizobium yuanmingense is a species of legume-root nodulating, endosymbiont nitrogen-fixing bacterium, associated with Lespedeza and Vigna species. Its type strain is CCBAU 10071(T) (= CFNEB 101(T)). [1]
Rhizobia are diazotrophic bacteria that fix nitrogen after becoming established inside the root nodules of legumes (Fabaceae). To express genes for nitrogen fixation, rhizobia require a plant host; they cannot independently fix nitrogen. In general, they are gram negative, motile, non-sporulating rods.
Ensifer meliloti are an aerobic, Gram-negative, and diazotrophic species of bacteria. S. meliloti are motile and possess a cluster of peritrichous flagella. S. meliloti fix atmospheric nitrogen into ammonia for their legume hosts, such as alfalfa. S. meliloti forms a symbiotic relationship with legumes from the genera Medicago, Melilotus and Trigonella, including the model legume Medicago truncatula. This symbiosis promotes the development of a plant organ, termed a root nodule. Because soil often contains a limited amount of nitrogen for plant use, the symbiotic relationship between S. meliloti and their legume hosts has agricultural applications. These techniques reduce the need for inorganic nitrogenous fertilizers.
Chamaebatia, also known as mountain misery, is a genus of two species of aromatic evergreen shrubs endemic to California. Its English common name derives from early settlers' experience with the plant's dense tangle and sticky, strong-smelling resin. They are actinorhizal, non-legumes capable of nitrogen fixation through symbiosis with the actinobacterium, Frankia.
Bradyrhizobium is a genus of Gram-negative soil bacteria, many of which fix nitrogen. Nitrogen fixation is an important part of the nitrogen cycle. Plants cannot use atmospheric nitrogen (N2); they must use nitrogen compounds such as nitrates.
Bradyrhizobium japonicum is a species of legume-root nodulating, microsymbiotic nitrogen-fixing bacteria. The species is one of many Gram-negative, rod-shaped bacteria commonly referred to as rhizobia. Within that broad classification, which has three groups, taxonomy studies using DNA sequencing indicate that B. japonicum belongs within homology group II.
Pararhizobium giardinii is a Gram negative root nodule bacteria. It forms nitrogen-fixing root nodules on legumes, being first isolated from those of Phaseolus vulgaris.
Rhizobium gallicum is a Gram-negative root-nodule bacterium. It forms nitrogen-fixing root nodules on legumes, being first isolated from those of Phaseolus vulgaris.
Bradyrhizobium arachidis is a species of legume-root nodulating, microsymbiotic nitrogen-fixing bacterium. It was first isolated from Arachis hypogaea root nodules in China. Its type strain is CCBAU 051107T.
Bradyrhizobium liaoningense is a species of legume-root nodulating, microsymbiotic nitrogen-fixing bacterium. It was first isolated from Glycine soja and Glycine max root nodules in China. Its type strain is strain 2281.
Azoarcus tolulyticus is a species of bacteria. It is a nitrogen-fixing bacteria. It is notable for degrading toluene. Tol-4 is its type strain.
Bradyrhizobium canariense is a species of legume-root nodulating, endosymbiont nitrogen-fixing bacterium. It is acid-tolerant and nodulates endemic genistoid legumes from the Canary Islands. The type strain is BTA-1T.
Mesorhizobium plurifarium is a species of root nodule bacteria first isolated from Acacia species in Senegal. Its type strain is ORS 1032.
Bradyrhizobium iriomotense is a species of legume-root nodulating, endosymbiont nitrogen-fixing bacterium, first isolated from Entada koshunensis. The type strain is EK05T.
Pelobacter carbinolicus is a species of bacteria that ferments 2,3-butanediol and acetoin. It is Gram-negative, strictly anaerobic and non-spore-forming. Gra Bd 1 is the type strain. Its genome has been sequenced.
Brucella lupini is a non-rhizobial root-nodulating bacterium. It nodulates Lupinus albus, hence its name. Strain LUP21T is the type strain.
Mesorhizobium mediterraneum is a bacterium from the genus Mesorhizobium, which was isolated from root nodule of the Chickpea in Spain. The species Rhizobium mediterraneum was subsequently transferred to Mesorhizobium mediterraneum. This species, along with many other closely related taxa, have been found to promote production of chickpea and other crops worldwide by forming symbiotic relationships.
Bradyrhizobium betae is a species of legume-root nodulating, microsymbiotic nitrogen-fixing bacterium first isolated from the roots of Beta vulgaris, hence its name. It is slow-growing an endophytic. The type strain is PL7HG1T.
Rhizobium lusitanum is a Gram negative root nodule bacteria, specifically nodulating Phaseolus vulgaris. Its type strain is P1-7T.
Chloroflexus aggregans is a thermophilic, filamentous, phototrophic bacterium that forms dense cell aggregates. Its type strain is strain MD-66.
Michael J. Sadowsky is an American microbiologist at the University of Minnesota. He is the director of the BioTechnology Institute and a Professor in the Department of Soil, Water, and Climate. Sadowsky's scientific career spans over 40 years, most of it focused on research studying the nature of bacteria and bacterial genes in ecological settings, with a particular emphasis on soil bacteria that are involved in nitrogen fixation.
