[KMnO4-induced change in the chemiluminescence of Pseudomonas aeruginosa cells after their preliminary interaction with pyocyanine].

Pyocyanin was capable of interacting with the cells when it was added to the cell suspensions of a Pseudomonas aeruginosa P. culture producing the pigment and a mutant that did produce pyocyanin. As a result, the intensity of chemiluminescence induced by KMnO4 in the cells decreased. Pyocyanin inhibited the chemiluminescence of the parent strain and mutant cell homogenates and their fractions, with an exception of the fraction of the mutant cell walls with which it did not react. The character of pyocyanin interaction with the cells of Ps. aeruginosa P. was shown to depend on the conditions of the cultural incubation.
