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.

摘要

测定了pH对铜绿假单胞菌在生物膜中导管上生长时细胞外毒力因子产生的影响。在pH 8时藻酸盐和蛋白酶的产生较高；相反，在pH 5时铁载体（绿脓菌素和绿脓杆菌素）的合成更为强烈。
