摘要
The present study was undertaken to investigate the possible inhibition of growth in Pseudomonas aeruginosa by interfering with its iron-uptake mechanism. Cobalt was employed as a possible competitive inhibitor of iron-uptake because of its similar size. The results indicate that cobalt competes effectively with iron for uptake by the bacterial cells and interference with iron-uptake could provide an effective means for inhibiting growth in P. aeruginosa.
