Isolation of noninhibitory strains of Zymomonas mobilis

Abstract

Wild-type Zymomonas mobilis strains inhibit the growth of Escherichia coli. We report the first isolation of noninhibitory strains, called Zymomonas inhibition negative (Zin-), after treatment with N-methyl-N'-nitro-N-nitrosoguanidine. A standardized soft-agar overlay procedure for detecting E. coli growth inhibition was also developed.
