Evaluation of anti-microorganism activities of some marine organism

141 marine samples have been tested for anti-microbial activity including representative: Gram positive bacteria, Gram negative bacteria, molds and yeast. Among them, 71 samples exhibited the positive result (accounted for 50.4 % of the total) against at least one of control microorganisms, 6 samples displayed the highest activity with the MIC value of 100 to 501/ml in the dillution method in 96- well plates. These data has been using to continue our programm in bioassay-guided chemical study
