Unclassified Bradyrhizobium

Unclassified Bradyrhizobium is a genus of Gram-negative Alphaproteobacteria that has not been classified into a specific Bradyrhizobium species.

Unclassified bacteria in the soil
There is a large diversity of bacteria in the soil. Research has shown that there can be between 2000 and 18000 prokaryotic genomes in 1 gram of fresh soil.

Soil microbiological communities are affected by many natural factors, such as humidity, temperature, light, atmospheric pressure and acidity of soil. Stress in the soil environment, often caused by extreme hydrological events such as flooding, changes the functional and structural biodiversity of soil bacteria.

Due to the many factors resulting in complicated changes to the bacteria in the soil, the tools used to describe microbial communities such as next generation sequencing and advances in bioinformatics analysis currently can only provide enough information to group bacteria into a certain genera, but not more specific than that.

Validated publications
There are a total of 70 validly published species of Bradyrhizobium under the International Code of Nomenclature of Prokaryotes (ICNP), the majority equipped with the function of fixing nitrogen.
