Fold-changes in extracellular metabolite abundances in Dhc195/DvH cultures amended with 20 μM As(III) as compared to the positive control at A) 5 hours after As(III) addition, B) 5 days after As(III) addition, and C) 22 days after As(III) addition and when TCE dechlorination function was regained and 80% of initial TCE had been consumed. Fold-change (FC) is expressed as (As(III)-amended/Control). Vertical dashed lines indicate a 2-fold change and the horizontal dashed line indicates p-value = 0.05. Metabolites falling outside the vertical lines and above the horizontal line are considered statistically significant and are colored red.
