Studies on Fungal Products. V. Antimicrobial Aspects of Quinone Derivatives

Abstract

The minimal inhibitory concentrations of cercosporin, isocercosporin from Cercospora kikuchii var. (MITTS-1 strain) and various quinones on bacteria and fungi were determined by the agar dilution method with Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli, and Monilia japonica. Gram-positive bacteria were more sensitive than gram-negative ones.
