Antibacterial activity of actinomycetes isolated from marine resources

Abstract

Antibacterial is very important in disease treatment and valuable in worldwide. The importance of this study is to discover a novel antibiotic for pharmaceutical industry from marine solated actinomycetes. The aims of this study are to determine the antibacterial activities compounds of marine isolated actinomycetes and genus identification of actinomycetes based on colony morphology and spore formation. The modification of agar disc diffusion method was used to screen antibacterial activities against six targeted bacteria and yeast. These samples were cultured in potato dextrose agar (PDA) and incubated for a period of 2-6 weeks. From a total of 30 actinomycetes isolates, 12 of them or 40% had shown positive result for antibacterial activities.
