    Abstract
    Phosphorus is a key nutrient in marine environment. Phosphate solubilising bacteria (PSB) have the ability to solubilise ionic forms of orthophosphoric acid to free form of phosphrous in the water column. Both PSB and alkaline phosphatase activity (APA) were estimated to appreciate their pattern of distribution and expression of activity off Trivandrum. Abundance of PSB (MPN and CFU) is more at near-shore stations (2.54x10 sup(5) and 1.65x10 sup(4)) when compared to off-shore stations (2.13x10 sup(5) and 4 0.90x10 sup(4)). However, PSA was more at off-shore stations (1.78 mu M/l/hr) than at near-shore locations (1.32 mu M/l/hr). Surface waters recorded higher activity (3.18 mu M/l/hr) than bottom (2.90 mu M/l/hr). Alkaline phosphatase responds to increase in temperature measured in these waters. Our studies suggest that the activity off coastal waters is stimulated by fall in levels of ambient phosphate concentrations. Detailed studies would help us to establish the threshold concentration of phosphorous that governs the alkaline phosphatase.
