Pyocyanin preparation from Pseudomonas aeruginosa isolated from heterogeneous clinical materials.
Pure pyocyanin was prepared from 120 strains of Pseudomonas aeruginosa isolated from different clinical specimens. The modified method used increased the purification 425-fold. The spectra of pyocyanin of all strains were found to be identical with a single major peak at 363 nm. The only difference between these spectra appeared to be the level value absorbance. Strains recovered from different clinical specimens differ in their ability for pigment production. The strains isolated from urine produced higher amounts of pyocyanin than other isolates.
