Fig. 4From: Natural combinatorial genetics and prolific polyamine production enable siderophore diversification in Serratia plymuthicaRelative abundance of serratiochelins, photobactin, and enterobactin in each mutant and wild-type strain. The low abundance of aerobactin did not allow for its relative quantification. Mean ± SD of 3 biological replicates with technical duplicatesBack to article page
