Inhibition of Sclerotium rolfsii by Pseudomonas aeruginosa

Abstract

Germination of sclerotia, growth, production by Sclerotium rolfsii were inhibited by the bacterium, Pseudomonas aeruginosa in culture and in soil. Inhibition of growth in soil was demonstrated by a new soil–agar plate technique. Preliminary evidence is presented which suggests that inhibition of S. rolfsii by P. aeruginosa is associated with the production of the antibiotic, pyocyanin.
