Each column heading provides the treatment condition and replicate. The first 4 letters are substrate abbreviation (provided below) followed by the bacterial identifier. The bacterial identity is either "WT" indicating the wildtype analog (pooled-RBTnSeq library) or four numbers indicating the locus tag of the disrupted gene (e.g. "1234" represents a mutant of "SPO1234"). Finally, the underscore and lowercase letter ("_a", "_b", "_c", "_d") indicates the biological replicate.
Values are optical density at 600 nm.
