Biocontrol Assay In Vivo. Using the results from the
in vitro antagonistic assay we were led to the selection of
ACTA1551 (Streptomyces rochei) so as to use it for in vivo
studies. This selection was based on its very high antifungal
activity expressed in vitro (Table 2) and the observation
from previous work [33, 56–60] that it is multiproducer of
bioactive substances.Thus, it was characterized as promising
biocontrol agent in vivo.
