Comparative analyses of the exometabolites produced by Sideroxydans sp. CL21 incubated with its’ own cell-free supernatant (50% v/v) (Sid(Sid)) versus Sideroxydans sp. CL21 incubated with the cell-free supernatant of S. oneidensis (50% v/v) (Sid(Shew)) after a 3 d (a) and 6 d (b) incubation period were conducted. Similarly, comparative analyses of the exometabolites produced by S. oneidensis incubated with its’ own cell-free supernatant (50% v/v) (Shew(Shew)) versus S. oneidensis incubated with the cell-free supernatant of Sideroxydans sp. CL21 (50% v/v) (Shew(Sid)) after a 3 d (c) and 6 d (d) incubation period were conducted. “_A, _B, or _C” corresponds to one replicate (n = 3).
