Nitrates

determine a certain bacteria, your tests will later on lead you down a certain side to contribute in defining the genus and species. All the following procedures were carried out on the gram positive cocci unknown in this order: Catalase, Oxidase, Nitrate Reduction, Oxidation-Fermentation, Phenol Red, Bacitracin, Coagulase, and lastly, Gelatin Hydrolysis. These tests led me to believe that unknown number 93 is Kocuria rosea. Discussion Looking at the dichotomous key, the first test that helps…

counter the argument into saying that eating red and processed meats don’t cause health issues. Nitrates are found in high concentrated amounts in vegetables that are naturally found in soil. But don’t get it confused nitrates that are found in meat are the same nitrates that are found in vegetables the two are still natural in which the body doesn’t know how to decipher between the two. Therefore, if nitrates are bad for you in meats they must be the same in…

had to repeat the same step for the citrate agar and nitrate broth. We inoculated the loop, took a small amount of our unknown bacterium, and mixed it in our two tubes containing the citrate agar and the nitrate broth and waited until next lab to continue the process. When we came back next week, we then added two drops of reagent in the nitrate broth to see if the color would change. After doing every experiment, it appeared that the nitrate color was red and the citric agar turned blue while…

lawsuit against three drainage districts north of the city on the Raccoon and Des Moines Rivers. They claim that there are massive problems with nitrates in Des Moines drinking water supplies. The company seems to believe that the nitrates have come from farm fields throughout the three districts: Sac, Calhoun, and Buena Vista countries. They claim that the nitrates leached out of agricultural fields into the drainage tiles which then ended up in the river and finally in the city’s drinking…

The country of Chile, simply somewhat bigger than the condition of Texas, attained freedom in 1818. Until 1830, the juvenile country was in a condition of tumult when Diego Portales introduced the time of the dictatorial republic. This period, from 1830-1861, was a period of firm-given principle tempered by control. Moderate landowners and traders were in control of an unified government, and a 1833 constitution persevered until 1925. The Conservatives, however tested by a reinforcing liberal…

will eventually end up in Lake of the Ozarks. This paper will be telling what those stream pollutants can do to water systems. Nitrates Nitrate is essential for all living things because it is a protein necessary for life. Now, it may be essential, but, ingesting large amounts through drinking water can be hazardous to small infants and pregnant women. Nitrate is commonly used in plant foods that are mixed with water. And also used for crop…

The role of sodium citrate is to reduce silver nitrate to silver (1). The role of D-glucose was to reduce silver nitrate into just silver, while soluble starch stabilizes the nanoparticles by surrounding them to prevent aggregation (1, 2, 3). The 1 M NaOH, 1 M HCl, and 1 M NaCl caused Batch A to aggregate. The nanoparticles aggregated with these reagents because these are all strong bases or strong acids, which dissociates completely and interacts with the oxidized citrate that separate the…

The atomic radius will slowly decrease as you move across a period on the periodic table; this is caused by the addition of protons found in the nuclei of the elements. For every new proton being added, several electrons will also be included into this process by joining the identical energy level (ultimately accounting for one electron per element in said period). The electrons then attract the protons, whilst failing to shield from or repulse this attraction. Given the above information, the…

We took 2 petri dishes that already had agar gel applied to them, and labeled them ‘Control’ and ‘Experimental’. We added 3 drops of the 1% Ammonium Nitrate solution using a dropper to the Control dish. We didn’t add anything to the Experimental dish in order to maintain the regular growth medium. We then inoculated each plate with three drops of the fern spores that we were given by the TA. And then…

since Enterobacter aerogenes is considered to be “facultative” based on page 85 of the lab manual appendix E (MB 352 Laboratory manual pg 37, 41, 85). Additional testing was done in lab 5, from which we utilized tests with “SIM agar deep tubes, nitrate reductase, protein hydrolysis, catalase, and cytochrome oxidase” (MB 352 Laboratory manual pg 48). The “SIM test” or “sulfide-Indole-Motility” had three parts to see “sulfide production”,…
