Abstract
Actinomycetes is a group of gram-positive bacteria that produce various secondary
metabolites and generally live in the soil, especially in the rhizosphere of plants
including Sandoricum koetjape. This study aimed to isolate and characterize
rhizosphere actinomycetes from S. koetjape plants. Soil samples were collected from the
plant rhizosphere, then diluted and inoculated by pour plate on SCA media. The
actinomycetes isolates obtained were characterized. The results showed that, seven
isolates of actinomycetes had circular and irregular colony shapes. The edges of the
colonies were serrate, entire, and undulate. Colony elevation could be raised, umbonate,
convex and flat. In addition, various color of the colonies were white, cream and gray.
