Biological Systems: Theory and Innovation

The purpose of this work was conducting study of the antibacterial activity of cultural filtrates of 125 micromycete strains isolated from different samples. Different Gram-negative and Gram-positive bacteria as test-organisms have been applicable.  Activity of 64 strains has been established. Genus Aspergillus and Penicillium was characterized wide spectrum of activity. The strains of genus Aureobasidium and Paecilomyces as A. pullulans 41, P. variotii 68 have been shown antibacterial action against test-organisms. It is found that strains of M. vinacea exhibited antibacterial activity against Staphylococcus aureus 904 and E. coli 906. Most strains did not show antibacterial effect. The results obtained confirm that antibacterial potential of strains of A. pullulans, P. variotii and M. vinacea is the most potential for researches of biologically active substances
