A high-density transposon library constructed in BW25113 was grown in the absence or presence of 0.25 mM or 0.5 mM sodium azide. In the case of the 0 mM and 0.25 mM samples, cells were grown until OD600 = 1.0. In the case of of the 0.5 mM sodium azide sample, the cells were grown to OD600 = 0.9, at which point the cells stopped growing exponentially. The location of the transposons after growth was determined using Illumina sequecing. Libraries were prepared using arbirary PCR and sequenced using single-end reads. Reads were then processed an aligned to the genome sequence for Escherichia coli K-12 strain W3110 (NCBI accession AP009048.1).
