1. Pesquisamos a atividade antibacteriana em 14 amostras de Aspergillus niger da National Collection of Type Cultures. 2. Em meio de Raulin e Mosseray, sete amostras apresentaram atividade total, nunca superior a 1:10, contra Staphylococcus aureus nº 553, sendo que as amostras 1.161 e 2.390 permaneceram ativas por mais de 40 dias. 3. A utilização do meio de Czapek-Dox com 5% de "corn-steep" não melhorou os resultados obtidos com o meio de Raulin e Mosseray. 4. No meio de levedo peptonado, todas as amostras apresentaram-se inativas. The Author investigated the antibacterial activity of 14 strains of Aspergillus niger from the National Collection of Type Cultures. In the Raulin & Mosseray medium, 7 strains presented total activity, never more than 1:10, against Staphylococcus aureus nº 553, The strains of the nrs. 1.161 and 2.390 remained active more than 40 days. The Czapek-Dox medium with 5% of corn-steep didi not improve the results obtained with the Raulin & Mosseray medium. In the yeast with peptone medium all the strains are inactive
