Streptomyces sp. MA02 is potential to produce various biological activities. In previous research, its extract shows antimicrobial activities. In this study, extract prepared from Streptomyces sp. MA02 stored at -80 oC was re-evaluated the antimicrobial activity on various medium and incubation time to find out storage effect toward the antimicrobial activity. We also evaluated n-hexane and ethyl acetic fractions toward the antimicrobial, antioxidant and toxicity activities. The extract Streptomyces sp. MA02 still inhibit tested microorganisms eventhough it decreases 50% than the extract prepared from Streptomyces sp. MA02 without -80 oC storage. Antimicrobial activity was only exhibited by the methanolic fraction Streptomyces sp. MA02. The methanolic and n-hexane fractions showed cytotoxic eventhough it was not for antioxidant activity in the linoleic acid system with ferrothiocyanate reagent (FTC).
