a Pre-cultures were grown under standard optimized conditions either in gradient tubes or in liquid media prior to inoculation of co-culture incubations. b Both organisms can also grow in monoculture in this incubation set-up. 16S rRNA gene copy abundances of Sideroxydans CL21 or S. oneidensis showing growth in monoculture and in co-culture over 9 days of incubation. Data points represent mean abundances (n = 3) from either Sideroxydans CL21 monocultures (open squares) or Sideroxydans CL21 in co-culture (closed squares) and mean abundances (n = 3) from S. oneidensis monocultures (open circles) or S. oneidensis in co-culture (closed circles). In b, a box with dashed lines is used to indicate that samples from the 6 d time point were used for RNA-seq. Error bars represent standard deviation in triplicate incubations. In some cases, error bars are smaller than the symbols.
