ABSTRACT
Seven species of marine diatoms were cultured under defined laboratory conditions. Air dried algal powder was used for extraction with different solvents in sequence. The algal extracts were tested against various bacteria by paper disc method. Nitzschia longissma, Skeletonema costatum and Biddulphia sinensis were effective against the test bacteria. Hemidiscus hardmannianus, Coscinodiscus centralis and Asterionella japonica showed moderate antibacterial activity. Pleurosigma elongatum exhibited no activity. The antibacterial substances were fully extracted by the organic solvents. Only in the active algal species, was activity noted in the aqueous extracts.
