Short summary

The aim of this paper was to determine the impact of citrate and malonate on microbial activity and community structure in uncontaminated and diesel-contaminated soil. The results suggest that these carboxylates can stimulate microbial activity and alter microbial community structure but appear to have a minimal effect on enhancing degradation of diesel. However, our results suggest that carboxylates may have an important role in shaping microbial communities even in contaminated soils.
