Item Evaluación in vitro de interacciones microbianas en hongos filamentosos aislados de suelos de hormigueros.(Universidad Santiago de Cali, 2024) Mosquera Gómez, Anyi Ximena; Rojas Barreto, Julián AlonsoFilamentous fungi are unicellular organisms that are characterized by the presence of filaments called hyphae, which allow them to spread and colonize various substrates. Within a community such as soil or other environments, different interactions can occur, because microorganisms cooperate when cell densities are low but compete when they are high and because of this they can interact positively or negatively in the environment they are in and ecosystem conditions. The purpose of this work was to identify the positive and negative microbial interactions between filamentous fungi isolated from anthill soils that will allow in the future to find solutions to problems in agriculture or ecology, for which two types of microbial interactions were evaluated ( synergism, antagonism) in 11 fungal isolates using the dual confrontation technique. Of the 55 interactions evaluated, 34 antagonistic interactions, 2 competitive interactions and 1 synergistic interaction were found. Five genera corresponding to filamentous fungi were taxonomically characterized, which were Trichoderma sp., Geotrichum sp., Penicillium sp., Fusarium sp and Phytophothora sp. Furthermore, Trichoderma sp strains confirmed their biocontrol role, when confronted with Fusarium sp, Phytophthora sp and Penicillium sp, all of which are described as phytopathogens.
