Biological control of wood decay fungi by Streptomyces strains's extract

The ability of actinomycetes to produce extracellular antifungal metabolites against fungal strains causing damages in the wood of the old Medina of Fez has been investigated. Two Streptomyces sp were screened for the inhibition of wood decay. Screening for antifungal activity of actinomycetes was performed with dual methods: the method of disk diffusion and the method of agar blocks. The result indicates that the crude extract of Streptomyces sp had a broad spectrum against fungi causing wood decay and inhibits their growth for more than 15 weeks; therefore it's could be an interesting source of antifungal bioactive substances.
