A bacterial strain producing a high concentration of red pigment isolated from sediment that had been collected East China Sea, Which was recorded as CH-34. It was identified as Zooshikella sp., as based on the biochemical properties and 16S rRNA gene sequence. CH-34 was grown in marine broth were incubated (120rpm, 25 ) for 10 days. They produced pigments with ℃ maximum absorption at 540 nm, which indicated the presence of prodigiosin, a well-known red pigment previously detected in Serratia marcescens1). This study was investigated the
antimicrobial activity of the culture broth(ZB), and bacterial cell(ZC). ZC and ZB extracts according to extraction solvents and fractions3). The antimicrobial activities of ZC and ZB extracts was tested against 21 microorganisms which were fish and human pathogens bacterial species. The extracts showd high activity against Streptococcus iniae, Streptococcus parauberis, Staphylococcus aureus Propionibacterium acnes, Streptococcus mutans and had poor effect on Serratia marcescens, Proteus mirabilis. Among the various solvent layers, the ZC methanol extraction (ZCEM) and ZC ether soluble fraction (ZCFE) showed strong
antimicrobial activities.
