Along with the high temperatures generated during the composting process, the microbial community of a
compost pile collaborates actively in the control of damping-off producing agents. Such collaboration could be
justified on the basis of the ability of the microbiota to produce fungicide substances that are involved in the
control of damping-off or other bioactive compounds that affect the growth promotion of plants. Thanks to ex situ
experiments, a remarkable suppressive effect was corroborated against different agents producing damping-off.
The microbial strains involved in this effect were detected mainly in the bio-oxidative and maturation phases of
the composting process. However, only 3% of the total collection of strains proved to have a multipotential
character with respect to its spectrum of action against the damping-off producing agents, as well as in relation to
its capacity to produce substances of agronomic interest. It is worth mentioning the presence of two th...
