CHARACTERIZATION AND IN VITRO ANTIFUNGAL ASSAY AGAINST FUSARIUM OXYSPORUM F. SP. PASSIFLORA OF ENDOPHYTIC ACTINOMYCETES FROM PURPLE PASSION FRUIT PLANTS OF SOUTH SULAWESI, INDONESIAALIMUDDIN ALI, MUHAMMAD JUNDA1, HILDA KARIM1 AND SRI NURYANIAbstract Endophytic actinomycetes from purple passion fruit were screened and evaluated for their antifungal activity against pathogenic fungi. A total of 32 isolates were obtained from people passion garden in Malino distric, South Sulawesi province, Indonesia. Morphological and chemotaxonomical analysis indicated that twenty-two isolates belonged to the streptomyces like-strain. This genus was the most dominant among the isolates (68.75%) of plant organs (roots, leaves and stem barks) of these showed inhibitory activity against Fusarium oxysporum f.sp. passiflora. Actinomycetes were most commonly recovered from leaves (50% of all isolates), followed by roots (43.75%) and stems (6.25%). Based on the phenotypic properties and phylogenetic and analysis of 16S rRNA gene, the selected strain EML-D1A5 was assigned to Streptomyces durhamensis strain CSSP538 (97% similarity).
