  Isolation and screening of antimicrobial-producing marine   actinomycetes has been conducted on isolates taken from West   Banten, North Cirebon, and South Yogyakarta Coasts. Two methods   pretreatments were applied i.e. acid and heat shock method. The   research 50 isolates. The screening reavealed four isolates which   has ability to inhibi Eschereschia coli, 5 isolates   could inhibited Streptococcus aereus, 4 isolates could   inhibited Bacillus subtilis, 4 isolates could inhibited   Pseudomonas aeroginosa, 5 isolats could inhibited   Candida albican, and 4 isolates
  could inhibited Aspergillus niger. Result of   identification morphology and DNA of isolate A11 it’s   Streptomyces sp. Morphology of isolate A11 haves   branching hyphae with spore sack at the end of hyphae. The   Minimum Inhibition Concentration (MIC) of isolate A11 to   Bacillus subtilis was 120,86 μg /ml.

  Key words: Isolation, Screening, Marine Actinomycetes,   Antimicrobial.
