From: Interaction between extracellular lipase LipA and the polysaccharide alginate of Pseudomonas aeruginosa

  1. The mucoid parent strain P. aeruginosa SG81 and its derivative strains (vector control SG81MCS, lipA mutant SG81ΔlipA, complementation strain SG81ΔlipA::lipA and lipA overexpression strain SG81lipA+) were tested. The results are expressed as mean values of four independent experiments.
