| Summary: | Nowdays there are many microbes that resistance to many antibiotics which is commonly used.
Therefore, it is necessary to find a new antibiotics. Sources of compounds with antimicrobial activity
can be found in various living organisms such as endophytic fungi and actinomycetes which can be
isolated from brown alga. Brown algae species can be found on Kaliage Kecil Island. This study aims
to isolate and test the antimicrobial activity of endophytic fungi and actinomycetes. The study
consisted of sampling brown algae, isolation and purification of endophytic fungi and actinomycetes,
fermentation and extraction of secondary metabolites, screening of antimicrobial activity,
determination of MIC and determination of MBC. Fermentation is carried out by agitation. Extraction
is done by liquid-liquid extraction and maceration using ethyl acetate as a solvent. Test microbe was
using Escherichia coli ATCC 8739, Staphylococcus aureus ATCC 6538, dan Candida albicans ATCC
10231. The results of the experiment obtain 3 isolates of actinomycetes and 11 Isolates of
Endophytic fungi Isolates. From the results of MIC testing on E. coli the lowest MIC value was showed

in this test indicates that the endophytic microbe of brown algae may be considered as a source of a
new drug.
