ABSTRACT
Marine Streptomyces GB-2, isolated from marine samples collected in the intel tidal zone of Lianyungang, was found to produce antibacterial substance which exhibited significant inhibitory effects on 11 Gram-positive bacteria and 4 Gram-negative bacteria. The antibacterial substance was proved to be neutral and water-soluble according to paper chromatogram analysis, and its production was significantly associated with aritificial seawater. The stability analysis of the fermentation broth of Streptomyces GB-2 showed that it was very stable at pH1 and pH12 under 121 degrees C and changed very little under ultraviolet treatment. The substance produced by strain GB-2 exhibited potential use in the areas of bio-control, food and medical application.
