A Novel Antimicrobial Substance from a Strain of the Bacterium,<i>Vibrio</i>SP

Abstract

Abstract The structure of a novel antimicrobial substance (1) isolated from a strain of the bacterium, Vibrio sp., was determined to be 7,7-bis(3-indolyl)-p-cresol on the basis of spectroscopic data. The substance showed specific inhibition against Bacillus subtilis with a minimum inhibitory concentration of 70 μg/ml but did not affect the growth of other test microorganisms.
