Investigation of iron's role in alginate production and mucoidy by Pseudomonas aeruginosa
Iron, an essential nutrient, influences the production of major virulence factors and the development of structured non-alginate biofilms in Pseudomonas aeruginosa. Fur, pyoverdine and various concentrations of iron sources have all been shown to affect non-alginate biofilm formation. Remarkably however, the role of iron in alginate biofilm formation and mucoidy is unknown. Because of alginate's association with biofilms in chronic cystic fibrosis (CF) lung infections, we examined the influence of iron on alginate production and mucoidy in P. aeruginosa. Herein, we identify and characterize a ...
