Bradyrhizobium and Burkholderia bacteria are common in these contaminated soils and help clean up metals and cycle nutrients.
Scientific Claim
Bradyrhizobium and Burkholderia bacterial genera are considered 'core' groups in Savannah River Site and Oak Ridge Reservation soils and provide critical ecosystem services such as metal detoxification and nutrient cycling.
Source Excerpt
“Bradyrhizobium and Burkholderia likely are the 'core' groups of bacteria in the SRS and ORR ecosystems and are primarily responsible for providing critical ecosystem-level services such as metal detoxification and cycling of nutrients.”
Evidence from Studies
Supporting Studies
A survey of bacterial and fungal community structure and functions in two long-term metalliferous soil habitats
The study identified these genera as consistently present across sites and noted their known roles in metal resistance and nutrient cycling based on previous research.
