The Sensitivities of Mixed Populations of Bacteria to Inhibitors

Abstract

A study was made oonoerning the effeots of mixed populations of Pseudomonas aeruginosa and Desulfovibrio desulfurioans on the sensitivities of the individual species to three groups of inhibitors. It was found that the presenoe of Ps. aeruginosa produced in some cases an increase in resistanoe of D. desulfuricans to substituted phenols, a consistent increase in resistanoe of D. desulfuricans to nitroparaffins, and had no marked effect on their sensitivity to mercurials.
