FIG 1.
Ecological interactions between strain 195, DvH, and S. wolfei in constructed consortia and the potential inhibitory effects of sulfate/sulfide. (A) Potential inhibitory effects of sulfate/sulfide on strain 195; (B) DvH and 195 in a syntrophic coculture with lactate as electron donor and sulfate addition; (C) DvH and 195 with H2 fed in excess as electron donor and sulfate addition; (D) DvH, 195, and S. wolfei triculture (S. wolfei/DvH/195) with butyrate as an electron donor and TCE and sulfate as electron acceptors. Acetate is the carbon source for the growth of 195. Dashed lines indicate a potential inhibitory effect.
