Antibacterial activity of the nitrogen fixers isolated from the Arabian Sea.

M. M. Taqui Khan and Sandhya Mishra

The antibacterial capacity towards the terrestrial pathogenic bacteria indicates the ecological niche of these isolates from the Arabian Sea. The N2 fixing bacteria fixes atmospheric molecular nitrogen (dissolved in seawater) to ammonia. Some portion of ammonia is assimilated and some of it is excreted in the surrounding medium. The excreted ammonia is toxic for the pahtogenic bacteria tested.
