Abstract:
The fungal endophytes associated with the O. basilicum var. thyrsiflora and its potential for providing antifungal compounds
were investigated. Fourteen fungal endophytes were isolated and cultured. Crude extracts of endophytes showed antifungal
properties against Trichoderma reesei and Lasiodiplodia theobromae. The crude extract of MFLUCC16-0609 played a role
as a great natural fungicide due to his inhibiting property against T. reesei and L. theobromae compared to other extracts.
Two major constituents including sclareolide (42.03%) and muzigadial (19.44%) were detected as the key antifungal
compounds. DNA-phylogeny-based and morphology-based genus analysis of strain MFLUCC16-0609 can be reconciled in
the Phanerochaete genus. Our results suggest that Phanerochaete sp. MFLUCC16-0609 may be a source of bioactive
compounds inhibiting or controlling plant disease pathogens.
