Description 6-9
Nitrifying capacity or the biological potential in nitrification of both sediments and overlying water were tested. Ammonia oxidizing bacteria and nitrite oxidizing bacteria were estimated both in water and sediments in 4 zones of Vellar Estuary, Tamil Nadu, India. Both marine and limnetic forms of bacteria were counted along with other environmental parameters. Generally, nitrification process was more in sediments than in the water column. Distribution of marine and limnetic forms of nitrifying bacteria was chiefly controlled by salinity. In the monsoon months, nitrifying bacteria of limnetic or terrestrial origin dominated the marine form. In other months, marine nitrifying bacteria were more in marine and tidal zones of the estuary with a decrease towards upstream. Salinity and substrate concentration (ammonia and nitrite) were found to be the chief controlling factors of these bacteria.
