title: Effect of pH on production of virulence factors by biofilm cells of Pseudomonas aeruginosa.
abstract: Effect of pH on production of extracellular virulence factors of Pseudomonas aeruginosa grown on catheter in biofilm was determined. Alginate and proteinase production was higher at pH 8; in contrast, siderophores (pyochelin and pyoverdin) were synthesized more intensively at pH 5.
