Abstract
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).
