Deletion of cpdB, together with ushA, does not abolish growth on eDNA as a sole source of phosphate.

This growth assay was performed using mid‐exponential phase bacteria, which were washed twice before putting into the test conditions. The growth medium used was MOPS‐glucose supplemented with either (A) sheared salmon sperm DNA consisting of 0.5 mM phosphate or (B) no phosphate source. The experiment was performed three times with a total of five biological replicates. Two biological replicates assayed in the same experiment are shown.
