Production of polyamines differs between 86-028NP and RM33 biofilms. The classical pathways for polyamine synthesis were adapted from KEGG. The red X indicates absence of known orthologs of enzymes involved in polyamine synthesis for 86-028NP. The mean and s.e.m. of the concentrations of the metabolites within three independent biological replicates 86-028NP (circle) and RM33 (square) 48 h biofilms were quantified as described in “Methods” section. Statistical significance was determined using a two-tailed unpaired Student’s t test (*p < 0.02; **p = 0.005). pp periplasm, cyto cytoplasm
