Abstract

Photobacteria phosoreum or Escherichia coli are widely used in the scientific, industrial, and regulatory industries for evaluating the toxicity of pollutants against the soil microbial community. The organisms, however, are not part of the soil microbiota and the toxicity data obtained using these organisms could be misleading. Analysis of microbiota present in the soil obtained from across the world indicates that organisms from the Bradyrhizobium genus are the most ubiquitous of all microorganisms. Playing a critical role in nitrogen fixation and soil fertility, organisms from this genus should be used for studying the toxicity of pollutants. Indeed, we propose that Bradyrhizobium japonicum USDA110 be used as a model organism for screening pollutants for toxicity against a soil microbial community.
