Similarly, isolated 800 strains of actinomycetes, and compared them with strains from the NBRC National Biological Reserch Center; 64 of them showed similarity to 36 Streptomyces NRBC, specifically to the Streptomyces griseus group, which has activity against Kocuria rhizophila and Aspergillus oryzae, and produces compounds such as streptomycin and bafilomycin, with antibacterial and antifungal activity, respectively. pointed to mechanisms of Streptomyces lydicus WYEC108 isolated from the rhizosphere of plants for controlling Pythium ultimum through antifungal compounds and extracellular chitinase, which destroy not only the spores, but also damage the hyphal cell wall; this showed that S. lydicus WYEC108 has biocontrol potential against P. ultimum.
