Abstract excerpt
Pseudomonas aeruginosa responds to phosphate limitation by inducing the expression of phosphate transport systems, phosphatases, hemolysins and a DNase, many of which are important for virulence. Here we report that under phosphate-limiting conditions, P. aeruginosa produces a phosphate-free ornithine lipid (OL) as the primary membrane lipid. The olsBA (PA4350-PA4351) genes were highly induced under...
