Ammonia production

Also known as azane, ammonia is a chemical compound with one nitrogen and three hydrogen atoms that are tightly bonded together; giving it the formula NH3. At room temperature, ammonia exists in a gaseous state with a colourless form and a pungent smell. It boils at -33.34°C and ammonia used for household uses is usually a mixture of ammonia and water. Ammonia provides the right conditions and nutrition that are needed for the growth of terrestrial organisms. Even in commercial products such as pharmaceuticals

Henri Louis Le Chatelier (i) Henri Louis Le Chatelier was a world renowned chemist known primarily for his work in developing “Le Chatelier’s Principle”. Henri was born to an academic bourgeoisie family on October 8th, 1850, in Paris France (1). Le Chatelier was fortunate as his father, Louis Le Chatelier, was able to teach him the basics of math and science, thus giving him a head start, and due to his parent’s status and wealth he was able to study at several universities (2). Le Chatelier’s earned

removed from the amino acid by a catabolic process called deamination. This process removes the amino group from the amino acid and converts it to ammonia (NH₃). The ammonia is highly toxic and must either be excreted quickly or converted to a less toxic waste product, such as urea or uric acid, and then excreted. Organisms that excrete nitrogen as ammonia (Fig. 1.2) are ammonotelic. Organisms that convert

nitrogen in ammonia makes many people think that it can double as fertilizer and promote plant growth. However, using household ammonia, which is present in many cleansers, can do more harm than good. Learning the ins and outs of this chemical and its effect on plant growth might make you think twice about using it. Ammonia and Plants Ammonia is presents in soil, water and air, and is an important source of nitrogen to plants. Nitrogen promotes plant growth and improves fruits and seed production, resulting

1.4 VAPOR ABSORPTION SYSTEM The attention of the vapor absorption system is growing in the past two decades. The major two advantages are growing up this technology that is low carbon emission technology and low electrical energy required. This system is operated with the help of low heating sources like solar power, geothermal, waste heat, low-pressure steam, and it contributes significant energy conservation. Ecofriendly working fluid leads to reduce the global warming and ozone layer depletion

The FDA and the USDA deem it safe for beef manufacturers to use ammonia in their meat filler. In fact “70% of meat filler contains ammonia” (Avila, “70 Percent of Ground Beef at Supermarkets Contains Pink Slime.”). Millions of Americans consume beef daily, and are unaware of what actually makes up the meat they are consuming. Because the hamburger is such a staple in many American’s diets it didn’t take long for someone to develop a cheap solution to produce more burger product for consumers, and

fish in the system. Larger biofilters have a great ammonia assimilation capacity and can support greater fish production [43]. From the fish tank water with high ammonia flows into the trickle filter. Since a water-trickles are down over the media, the large surface area and oxygen from the atmosphere allow nitrification bacteria to oxidize ammonia to nitrite and nitrate. Afterwards, the water exits the trickle filter with much reduced ammonia content (see Figure 11) [36]. Trickling filters are

are two arrangements of water quality parameters:  Conservative  Non-conservative Conservative parameters of water which are hardness, alkalinity, salinity, and temperature are not affected significantly by activities of microorganisms. [30] Ammonia, nitrate, nitrite, total nitrogen, pH, phosphorous, dissolved oxygen, conductivity, total dissolved solids, chemical oxygen demand, and oxygen reduction potential which are affected by biological activity are considered as non-conservative.

used to see if the microbe can hydrolyzes urea to ammonia and carbon dioxide. When there is an alkaline environment the color turns to pink. Turning pink would present a positive result. The SIM test tested negative for sulfur reduction presenting no sign of the color black, positive for indole production presenting the color red, and positive for motility. Sulfur reduction is a test used to differentiate enteric bacteria. The indole production test differentiates Enterobacteriaceae. For testing

nitrification and denitrification (Postgate 1998). The process of conversion of molecular nitrogen to ammonia is known as nitrogen fixation. Biological nitrogen fixation is the mechanism of reduction of atmospheric nitrogen to a metabolically active form exclusively by microorganisms. Biological nitrogen-fixation (BNF) involves the enzymatic reduction of N2 to ammonia (NH3-). Conversion of N2 to ammonia is catalyzed by a metalloenzyme called nitrogenase. Reaction has a high activation energy because
