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.
