MICROBES DEPENDENT DENITRIFICATION OF CONTAMINATED WATER INTRODUCTION:- This is an eco-friendly and economical project. In this we want to show how to reduce the harmful effects of nitrogen which gets mixed with water by natural hazard or else by man-made hazards. With the help of two types of bacteria like thiobascillus and rod shaped bacteria of bacillus species‚ we want to reduce the adverse effects of the dissolved nitrogen in the water bodies. HYPOTHESIS:- Nitrate-rich water containing denitrifying

The reaction between nitric acid and sulfuric acid resulted in the formation of nitronium ion NO2+. It then acted as strong electrophile that nitrated the benzene ring. After that‚ vacuum filtration and recrystallization were methods used to obtain the final product with minimal impurities. The mass of product
