Effect of 0.85 mM Cr(VI) on protein concentration, HS− production, and Cr(VI) reduction by the sulfidogenic enrichment consortium, MI-S, from MINSY. (A) Protein concentration of the control enrichment without Cr(VI) (⧫) and the experimental enrichment subjected to 0.85 mM Cr(VI) (□). (B) HS− production by the control enrichment (⧫) and the experimental enrichment subjected to 0.85 mM Cr(VI) (□). (C) Reduction of 0.85 mM Cr(VI) by medium alone (⧫) and by MI-S (□). Error bars are standard deviations for duplicate experiments.
