Cobamide-based interactions between soil bacteria can be predicted based on monoculture growth

Zoila I. Alvarez-Aponte, Hazel I. Anagu, Kenny C. Mok…·Michiko E. Taga

The paper shows that cobamide concentrations predict microbial dominance in co-cultures, suggesting niche differentiation despite functional redundancy.

Quenching corrinoid-based interactions in a model bacterial coculture.

Zachary F. Hallberg, Zoila I. Alvarez-Aponte, Allison Gaudinier, Michiko E. Taga

This paper develops a method to disrupt specific microbial metabolic interactions by quenching corrinoids using BtuG, showing it blocks corrinoid-dependent growth and measures cobalamin release rates in a model bacterial coculture.
