The preeminent storage form of phosphorus in standard poultry and swine diets is phytic acid. This phytic acid (myo-inositol hexakisphosphate), also designated as phytate phosphate, is estimated to comprise about 70% of the total phosphorus found in cereal grains, oilseeds, legumes, corns and soya beans which are the prime elements in the feeds of poultry and swine (Reddy et al., 1982; Al-Asheh & Duvnjak, 1995; Lan et al., 2002a). It has been reported previously that the total phosphorus within the animal feed is ideal for the growth of poultry provided that this phosphorus is able to be utilized in vivo (Lan et al., 2002a). However, due to inadequate gastrointestinal enzyme, most monogastric animals (such as pigs, poultry, fish, etc) are unable to hydrolyze the phytic acid and therefore incapable of liberating free phosphorus for absorptions (Common, 1989).
The ineptitude of the monogastric animals to fully hydrolyze the phytic acid resulted in several problems. For instances, supplementation of inorganic phosphate, which is expensive, is needed to compensate with the inability of the monogastric animals to utilize phytic acid. The supplementation of inorganic phosphate in the animal feeds is crucial to meet the animals’ dietary requirements. Furthermore, the unutilized phytate-phosphorus causes the concentration of phosphorus in the animals’ excreta increases and this will indirectly contributes to serious phosphorus pollution complication (Pen et al., 1993; Volfova et al., 1994). Cyanobacterial blooms, hypoxia and death of marine animals have been reported to occur as a consequence of the eutrophication of the rivers by this excessive phosphorus (Mallin, 2000; Naqvi et al., 2000). In fact, phytic acid has been well-known for ...

...osphorus and other essential trace elements in non-ruminants feed (Lan et al., 2011). Nevertheless, the Mitsuokella jalaludinii is an anaerobic bacterium and therefore need rigid growth conditions for it to be mass produced. One of the possible solutions for this problem is to clone and express the phytase genes into other microorganisms which are aerobe or facultative anaerobe in nature without compromising its existing phytase activity. The whole genome of Mitsuokella jalaludinii has been sequenced and the genes responsible for the expression of phytase, Phy1 and Phy2, were identified through the gene annotation of the genome and are in close proximity to each other. As such, the need for cloning and further expression of the Mitsuokella jalaludinii phytase is essential to identify the potential of this enzyme to be largely produce for commercialization purposes.
Methionine represents the first limiting amino acid in broiler nutrition, thus different sources are available to balance diets based of corn and soybean. Bioavailability is different for each methionine source because of its rate of absorption and metabolic pathways. A broiler experiment was conducted to determine the relative bioavailability of Hydroxyl Methyl Analog Calcium (HMA-Ca) relative to DL-Methionine(DL-Met). The experiment was conducted at at Lavinesp (Unesp, Jaboticabal). It was used 1890 male broiler Cobb 500 of 21 days old, they were weighted and distributed homogeneously in a complete randomized design with 13 treatments and 7 replicates each. All birds fed either a basal diet deficient in sulphur amino acids, digestible methionine and cysteine (dig Met+Cys), or the basal diet with four levels of HMA-Ca (0.063, 0.183, 0.302 and 0.540%) and DL-Met (0.054, 0.156, 0.259 and 0.463%) to achieve increasing levels of dig Met+Cys. For the analysis, 5% of significance was considered and procedures of non-linear model were used by SAS. Exponential regression determinates bioavailability of HMA-Ca relative to DL-Met by calculating the relation of the slope of HMA-Ca relative to DL-Met

If nitrate and phospahte level is present in an area an increased amount of detritus will also be present due to the death and decay of the submerged plants. This provides an ideal food source for the Gammurus pulex and increases the chances of survival and reproduction. As a result you would expect to see an increase in the abundance of the species in polluted stream.
Introduction: The question that the researcher is trying to answer is if there is acidification alters oceanic life due to a change in pH. The hypothesis is if there is a change in pH in the tank then the fish will have altered feeding patterns, stunted growth, and abnormal behavior. Even if there is a slight change in pH distinct abnormalities will occur. This simulation of this experiment will represent a sample for the whole ocean and how pH has affected ocean life due to runoff and toxic waste put into the water.
We believe that there are three possibilities why phosphate levels are really high at Creepy Pond. One
The lake receives all of the storm runoff water from the land around it which is what causes the lake to be overrun with phosphorus. Phosphorus is actually considered a nutrient for the lake and is essential for the survival of a lot of the lake’s plant life. However, too much of the element impacts the biodiversity of the lake: there is a large increase in algae, which in turn, affects the rest of the life in the lake. Winnipesaukee Gateway lists more effects: decrease in water clarity, increased chlorophyll-a, increased cloudiness of the water, and decreased oxygen
Pennsylvania has the most acid rain in the country, so it is not a surprise if the creek was polluted, but it’s not. It could be because of limestone rocks, or rocks that neutralize pollution in waters. Are next experiment was a eutrophication Test. A eutrophication is an enrichment of an ecosystem with chemical nutrients typically compounds containing nitrogen, phosphorus, or both. In this test we took samples of water into clear measurable tubes. There is 3 things we tested with water, Phosphate, nitrate, and dissolved oxygen. Phosphates and nitrates are examples of polyatomic ion. Phosphates and nitrates are found in fertilizers and some detergents. We tested for them and we didn’t get big results, so we know that waters aren’t polluted. There was a lot of dissolved oxygen, which is good, because that is what fish need to
These reseachers extracted the Escherichia coli gene that produces phytase in E. Coli bacteria and attached this gene to a Mus musculus—house mouse—gene called a parotid secretory protein promoter. This mouse gene is a protein associated with secreting digestive enzymes from the salivary glands of mice, and can be used in pigs in the same fashion; by linking these two genes together and inserting it into the genome of a pig, the scientists hypothesized that a transgenic pig should have the ability to secrete the E. Coli phytase enzyme in their saliva to break down phytate into accessible phosphorous. These researchers tested their hypothesis by producing 33 transgenic piglets, 14 of which were capable of producing significant amounts of phytase in their salivary glands. These piglets were then crossed to make subsequent generations for transgenic pigs, which had an even higher capability to produce salivary phytase. These pigs were then tested on their ability to utilize phytase by testing the concentration of phosphorus in their feces. Transgenic pigs in

Phosphorus is an important part of the human bones, it is good for the brain, kidney, heart, and blood. Majority of your body contains 85% of phosphorus in your body. Phosphorus is found in protein- rich food like meats, poultry, fish, nuts, beans and dairy products. Phosphorus is a Greek word for light bearing. On the periodic table phosphorus is a chemical element with the symbol (P) and is also a nonmetal. Phosphorus was discovered in 1669 by Hennig Brand, who was a German physician and alchemist. Hennig Brand thought that he could turn phosphorus in urine into gold, but everytime he tried he ended up getting a white, waxy substance that glowed in the dark. When Hennig Brand didn’t succeed phosphorus became an element used in deadly explosives.
There are various reasons as to why Enviropigs are beneficial and valuable to society, one of the most prominent reasons being it decreases the deaths of marine wildlife and oxygen pollution. Phosphorus, the chemical which pig cells need to make DNA, build cell membranes and transport and generate energy, is a major cause to the marine wildlife deaths. In the manure of a normal pig, there is a high concentration of phosphorus, which can lead to oxygen “dead zones”, if the waste washes into the ocean. A low concentration of phosphorus is key to clean water. Envi...
Eutrophication is “the process by which a body of water acquires a high concentration of nutrients, especially phosphates and nitrates. These typically promote excessive growth of algae. As the algae die and decompose, high levels of organic matter and the decomposing organisms deplete the water available oxygen, cause the death of other organisms, such as fish. Eutrophication is a natu...
I am particularly surprised how the agricultural industry inflicts these problems on themselves, by excessive use of sewage systems and pollutants which find their way to local rivers [Fig 1.]. The trophic state (i.e. the natural nutrition factors) and biodiversity of lakes and rivers are greatly effected by the main nutrients involved, nitrates and phosphates. The transition occurs mainly between a mesotropic state, with an average biological productivity to a eutrophic state where there is a larger production of organisms due to high nutrient concentrations. Tropical reservoirs in particular often become eutrophic.
