Figure 4From: Characterization of N-acylhomoserine lactone-degrading bacteria associated with the Zingiber officinale (ginger) rhizosphere: Co-existence of quorum quenching and quorum sensing in Acinetobacter and BurkholderiaQuenching of elastase production and lecA expression in P. aeruginosa by ginger rhizosphere strains. (A) Elastase production by P. aeruginosa following monoculture (PAO1) or in co-culture with GG2 (PAO1+GG2), GG4 (PAO1+GG4) or Se14 (PAO1+Se14) at a starting inoculum ratio of 1:1 for 24 h. (B) Expression of a lecA::lux fusion following monoculture or co-culture of P. aeruginosa PAO1 with GG2, GG4 or Se14 at a starting inoculum ratio of 1:1 for 24 h. The data are presented as RLU/OD to account for any differences in growth.Back to article page
