Antagonistic activity of a natural fungal population towards pathogenic bacteria. An in vitro study.
In the present work, we performed in vitro testing of 33 species of fungi of the subdivision Deuteromycotina isolated from water and sediment of the Kolubara River for antagonistic action towards 11 species of pathogenic bacteria. Of gram-negative bacteria, the species most sensitive to metabolic fluid of the fungi were Proteus mirabilis, Salmonella enteritidis, and Shigella sonnei, while the most resistant were Klebsiella pneumoniae and Salmonella typhimurium. Of gram-positive bacteria, the most sensitive species was Staphylococcus aureus, while the most resistant was Enterococcus faecalis. Of the tested fungi, Penicillium canescens, P. simplicissimum, P. thomii, Aspergillus fumigatus, A. ochraceus, and Fusarium culmorum exerted inhibitory action on the greatest number of species of pathogenic bacteria, while Verticillium lateritium, V. tenerum, Phoma humicola, and Botrytis cinerea had an inhibiting effect on the least number of species.
