Antimicrobial activity of fungi strains of Trichoderma from Middle Siberia

The antibiotic activity in 42 strains of 8 species of the Trichoderma genus (T. asperellum, T. viride, T. hamatum,T. koningii, T. atroviride, T. harzianum, T. Citrinoviride, and T. longibrachiatum) isolated from different Siberian ecotops was studied. It was shown that these species differ in the de...

Description
Summary:The antibiotic activity in 42 strains of 8 species of the Trichoderma genus (T. asperellum, T. viride, T. hamatum,T. koningii, T. atroviride, T. harzianum, T. Citrinoviride, and T. longibrachiatum) isolated from different Siberian ecotops was studied. It was shown that these species differ in the degree of their antibacterial and antifungal activity. The chosen strain, T. citrinoviride TV4-1, exhibited high activity and a wide range of actions against the opportunistic and pathogenic fungi of the Aspergillus and Candida albicans genus; bacteria, including methicillin-resistant Staphylococcus aureus; and cancer cells. According to mass and IR spectrometry data and the spectrum of biological action, peptaibols are probably the most active compounds in the strain culture extracts.
