Conclusion
The present study indicates the usefulness of whole
culture broth and methanolic extract of the locally isolated
actinomycetes especially, under the genus, Streptomyces
for medicinal and biotechnological purposes. The further
chemical investigation using GC-MS for the presence of
antifungal metabolites might indicate its potentiality as a
source of novel useful antifungal antibiotics for the local
tomato seedlings and other plants in Saudi Arabia and
worldwide.
