Partial characterization and antimicrobial spectrum of inhibitory substances from marine Alteromonas

Descripción del Articulo

Inhibitory substances produced by marine strains belonging to the genus Alteromonas spp. are partially characterized. Precipitation of raw extracts supernatans from strains N22.C and N11.6 with concentration saturants of ammonium sulfate and filtrates in columns Sephadex G-25 show the production of...
