2,6 pyridine dicarboxylic acid (DPA) is a small molecule that is produced by gram-positive spore forming bacteria. DPA was first discovered as a key component of bacterial endospores, which was found that DPA composes 10% of the spore’s dry weight. The accumulation of DPA in the spore is believed to facilitate diffusion of Ca2+, which in turn chelates to DPA to form a small molecule DPA:Ca2+ complex. In our research we tested DPA’s affinity for water soluble aluminum, and the bioremediation of a DPA:aluminum complex by soil bacteria. Our results suggest that DPA effectively binds to aluminum and that bacteria has the ability to grow in presence of the DPA:aluminum complex.
