Figure 3: OMV production from P. aeruginosa under the ciprofloxacin-induced SOS response. (a) Growth of the wild-type (PAO1) and the LexA noncleavable strains. Both strain were grown in LB with shaking for 2 hrs, and then ciprofloxacin (CPX) was added. The culture continued for 6 hrs. OMVs were isolated from the wild-type and the lexAN cells treated with or without ciprofloxacin (CPX). (b) Quantification of OMV proteins by Bradford ( 𝑛 = 7 ) and (c) OMV lipids by weight ( 𝑛 = 3 ). ( 𝑃 < 0 . 0 5 ).
