(A) Degradation of cDCE by JS666 (solid lines and symbols; OD600 ≈ 1) and transformation by JS595 (dashed lines, open symbols; OD600 ≈ 40) and uninoculated control (open circle, dotted line). Circles, cDCE; squares, 2,2-dichloroacetaldehyde; diamonds, unknown metabolite. (B) Mass spectrum of unknown. (C) Mass spectrum of 2, 2-dichloroacetaldehyde.
