Development of Molecular Identification of Nitrifying Bacteria in Water Bodies of East Kolkata Wetland, West Bengal

Mousumi Saha, Agniswar Sarkar and Bidyut Bandhophadhyay

Nitrifying bacteria plays a major role in converting the waste water to valuable renewable resources for the society. Ammonia is the toxic excretory product of most aquatic organisms and nitrite formed by the oxidation of ammonia is also toxic. Ammonia oxidizing bacteria converts ammonia to nitrite and Nitrite oxidizing bacteria convert nitrite to nitrate. Among them, Nitrosomonas sp. and Nitrobacter sp. has been the most widely studied organisms. An advanced molecular technique made it possible to explore the nitrifying bacteria in the environment and to enhance our knowledge of its functioning. In view of this it would be of prime importance for rapid detection of these strains/ isolates using molecular techniques. The present study was undertaken to develop and validate 16S rDNA sequence analysis of Nitrosomonas sp. and Nitrobacter sp. collected from different bheries in East Kolkata Wetland, West Bengal.
