Resumen
[EN] Self-inhibitory processes are a common feature shared by di erent organisms. One of
the main mechanisms involved in these interactions regarding microorganisms is the release of
toxic di usible substances into the environment. These metabolites can exert both antimicrobial
e ects against other organisms as well as self-inhibitory ones. The in vitro evaluation of these
e ects against other organisms has been widely used to identify potential biocontrol agents against
phytopathogenic microorganisms. In the present study, we performed membrane assays to compare
the self-inhibitory e ects of soluble metabolites produced by several Trichoderma isolates and their
antifungal activity against a phytopathogenic strain of Fusarium oxysporum. The results demonstrated
that Trichoderma spp. present a high self-inhibitory activity in vitro, being a ected in both their
growth rate and the macroscopic structure of their colonies. These e ects were highly similar to
those exerted against F. oxysporum in the same conditions, showing no significant di erences in
most cases. Consequently, membrane assays may not be very informative by themselves to assess
putative biocontrol capabilities. Therefore, di erent methods, or a combination of antifungal and
self-inhibitory experiments, could be a better approach to evaluate the potential biocontrol activity of
microbial strains in order to pre-select them for further in vivo trials.
