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

The paper characterizes bacterial cobamide preferences by testing growth under specific cobamide-dependent conditions, revealing broad diversity in cobamide usage across organisms and metabolic pathways.

This study evolves E. coli with a less-effective cobamide to identify genetic adaptations that improve growth, finding increased BtuB expression and BtuR overexpression enhance cobamide-dependent growth.

The paper investigates corrinoid production and dependence in soil bacteria to understand metabolic interactions, finding metabolic compatibility and conserved traits across genera.

The paper investigates how corrinoid structure affects soil microbial community composition and stability through experimental and genomic analysis.
