Abstract

A new sterol, 7-aminocholesterol, which inhibits growth of Saccharomyces cerevisiae, also displayed antibiotic activity against Gram-positive bacteria. The 50% growth inhibitory concentration against strains of Listeria innocua L. monocytogenes, Staphylococcus aureus, Enterococcus hirae and Bacillus cereus was 3 μM.
