(a) Cell concentrations of the enrichment cultures calculated from qPCR data of A_DKE, B_DKE and C_DKE, (b) with corresponding pH values and Fe(II) concentrations over a time period of 11 weeks. Corresponding CARD-FISH pictures of enrichment cultures showing: (c) co-culture after four weeks of growth (B_DKE and C_DKE stained in red (ARCH915, Alexa 546) and A_DKE stained in green (ARM980, Alexa 488)) and (d) after eight weeks of growth (again B_DKE and C_DKE stained in red (ARCH915, Alexa 546) and A_DKE stained in green (ARM980, Alexa 488)).
