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 bacteria will exhibit a faster rate of reduction in nitrate levels. OBJECTIVE:- To denitrify nitrogen (Nitrate and nitrite) rich water.

AFFECTING SULFUR MINERALIZATION Sulfur content of organic matter Mineralization of sulfur depends on the sulfur content of the decomposing material in much the same way that nitrogen mineralization depends on the nitrogen content. Smaller amounts of S042- are liberated from low sulfur containing residue‚ which is similar to nitrogen mineralization. At or below a C/S ratio of approximately 200/1 only mineralization of sulfur occurs. Source of mineralizable sulfur Because of the contribution of sulfur

Nitrogen in the air enters and leaves living systems by way of the nitrogen cycle. Describe the events which take place when atmospheric nitrogen molecules move along a food chain (involving legumes and herbivorous mammals) and eventually return to the atmosphere. In your answer‚ describe the uptake‚ processing and utilization of nitrogen in the bodies of these organisms Atmospheric nitrogen in air enters by diffusion or gaseous exchange and leaves the bodies of most organisms without biotransformation

The human’s impact on The Nitrogen Cycle would have to be the substantial of the human involvements. This cycle is also has both processes benefit human welfare profoundly and the humans action to more than double the rate at which nitrogen is moved from the atmosphere to the land. * Give specific examples of each cycle and how humans impact these cycles.

module‚ xxxx. 2. Body 2.1 What melamine is and its uses According to World Health Organisation (WHO)‚ melamine is an organic base compound that is mostly found in the form of white crystals. With high nitrogen content‚ melamine has more than 5 times nitrogen compared to proline‚ a type of amino acid commonly found in milk. Being a relatively cheap industrial material that is durable‚ relatively non-toxic and water-soluble‚ melamine is used to make utensils‚ dishware and resins

10−4 to 10−6). This basicity is due to the unshared electron pair on the nitrogen atom. Classification and nomenclature of amines Amines are classified as primary‚ secondary‚ or tertiary based upon the number of carbon-containing groups that are attached to the nitrogen atom. Those amine compounds that have only one group attached to the nitrogen atom are primary‚ while those with two or three groups attached to the nitrogen atom are secondary and tertiary‚ respectively. In the common

which one or more H atoms are substituted by an alkyl or aromatic group. Amide - an organic compound with a carbonyl functional group (C=O) bonded to a nitrogen atom. Amines are the smaller and simpler products of the decomposition of larger and more complex organic compounds like proteins. They often have foul odours‚ as do many nitrogen compounds‚ such as the smell of rotting fish and decomposing animal tissue and are produced by bacteria. Can be found in many biological‚ including amino
