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 paxllaeri is a bacterium from the genus of Bradyrhizobium.
Bradyrhizobium retamae is a bacterium from the genus of Bradyrhizobium.
Pontibacter diazotrophicus is a nitrogen-fixing, Gram-negative and rod-shaped bacterium from the genus Pontibacter which has been isolated from sand from the Taklamakan Desert, China.
Microbacterium shaanxiense is a Gram-positive and non-motile bacterium from the genus Microbacterium which has been isolated from the surface of a root nodule from a soybean.
Phyllobacterium sophorae is a Gram-negative bacteria in the genus Phyllobacterium which has been isolated from the root nodules of the plant Sophora flavescens.
Bosea vaviloviae is a Gram-negative and rod-shaped bacterium from the genus of Bosea which has been isolated from the nodules of the plant Vavilovia formosa.
Bradyrhizobium embrapense is a nitrogen-fixing bacterium from the genus of Bradyrhizobium.
Bradyrhizobium guangdongense is a bacterium from the genus of Bradyrhizobium which has been isolated from the effective nodules of a peanut plant.
Bradyrhizobium subterraneum is a nitrogen-fixing bacterium from the genus of Bradyrhizobium which has been isolated from the effective nodules of the peanut Arachis hypogaea.
