Çeşitli Trichoderma İzolatlarının Bazı İnsan ve Bitki Patojeni Bakteriler Üzerindeki Antibakteriyel Etkisinin in vitro Koşullarda Taranması

The increasing global antibacterial resistance constitutes a major public health issue. Consequently, there is a substantial growing need for effective new antibacterial compounds for the treatment and prevention of bacterial infections. This is where the concept of biological control comes into play. In particular, fungi of the Trichoderma Pers. species play a significant role in this biological control. Investigating the effects of biological control agents such as Trichoderma spp. in combating pathogens and controlling diseases in both agricultural production and human infections represents an important area of research. The aim of this study is to determine the antibacterial effects of metabolites from previously isolated local and unique Trichoderma isolates against some plant and human pathogenic bacteria under in vitro conditions. Among the Trichoderma isolates (n=30) tested, 11 showed antibacterial activity against Escherichia coli, 6 against Staphylococcus aureus, 18 against Pseudomonas aeruginosa, 5 against Pseudomonas cichorii, and 20 against P. syringae pv. tomato. Our study shows that antibacterial metabolites obtained from Trichoderma isolates have the potential to control of pathogens.
