title: Isolation and structure determination of an antimicrobial ester from a marine sediment-derived bacterium.
abstract: A new compound, assigned the trivial name bonactin (1), has been isolated from the liquid culture of a Streptomyces sp. BD21-2 obtained from a shallow-water sediment sample collected at Kailua Beach, Oahu, Hawaii. Structure elucidation employed one- and two-dimensional NMR, HRFABMS, IR, and chemical analysis. Bonactin displayed antimicrobial activity against both Gram-positive and Gram-negative bacteria as well as antifungal activity.
