    ISOLASI DAN KARAKTERISASI PARSIAL AKTINOMISETES DARI TANAH MANGROVE Avicennia alba Blume
    (perpustakaan UR, 2021-10) Kurniafebi, Fitri Aulia; Roza, Rodesia Mustika
    Actinomycetes are gram-positive bacteria that have the ability to adapt in various environmental conditions. Mangrove forests are one of the ecosystems that have extreme environmental conditions. The purpose of this study was to explore and characterize activities of actinomycetes isolated from soil where Avicennia alba Blume population grown in Kuala Enok. Soil samples were taken from three different points. Isolation of actinomycetes using pour plate method with Starch Casein Agar (SCA) media. The results of isolation obtained in this study was four actinomycetes with varied morphology. Microscopic characteristics showed that the isolates are positive gram. In addition, biochemical tests showed negative results on catalase tests, while in amylase tests A4 isolates showed positive result.
