Antibacterial activity from bacteria isolate from marine resources

Abstract

The important of this study is to determine antibacterial activity for marine bacteria which isolated from marine resources such as marine sediments, corals, sea cucumbers, sponges, drift woods, sea water, decayed leaf and mollusks. Culture of marine bacteria which stocked at Institute Marine of Biotechnology was used as inoculums. The modification of agar disc diffusion method were used to screen antibacterial activity against six pathogenic bacteria which are Aeromonas hydrophila, Bacillus subtilis, Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus and Streptococcus agalactiae, also one fungi which is Saccharomyces cerivisiae. From total 153 marine bacteria which had been screened, 92 of them were shown antibacterial activities towards at least one pathogenic bacteria which act as target bacteria.
