Abstract:
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.
