Effect of thorium on the growth and capsule morphology of Bradyrhizobium.
A specific defence mechanism based on metal precipitation by extracellular polymers is suggested, which is mainly in the amorphous fraction of Bradyrhizobium (Chamaecytisus) BGA-1. Expand
Coprecipitation of Th4+ and the purified extracellular polysaccharide produced by bacterium Bradyrhizobium (Chamaecytisus) BGA-1
The soil bacterium Bradyrhizobium (Chamaecytisus) strain BGA-1 produces an extracellular polymeric substance (EPS) that, in the presence of Fe3+, Al3+ or Th4+ solutions, forms a gel-like precipitateExpand
