the hospital recently and brought a sample their infectious disease on an agar plate. A series of tests were completed in order to identify this unknown sample. First‚ the plate was analyzed for its hemolysis characteristics. Afterwards‚ a Gram stain was performed from a sample of the agar plate and the slide was viewed under the microscope. Once‚ the microscopic visual was captured‚ a catalase test followed. Next‚ for further data‚ MSA results were recorded‚ along with antibiotic observations of

Boake‚ Hannah Harper Various Color of Light as the Effect of Electron Emission Objective Observe the characteristic colors produced by certain metallic ions when vaporized in a flame. Identify the unknown metallic ions by means of its flame tests. Background When atoms absorb energy‚ electrons move into higher energy levels‚ and these electrons lose energy by emitting light when they return to lower energy levels. Energy levels are fixed energies that electrons can have. Ordinary light

Food Test 1: Test for Glucose – with Benedicts solution Benedicts solution is used to test for simple sugars‚ such as glucose. It is a clear blue solution of sodium and copper salts. In presence of simple sugars‚ the blue solution changes color to either green‚ yellow or brick-red‚ depending on the amount of sugar. Method 1) Mix smalls amount of each food sample (i.e.‚ Egg lumen‚ cylindrical piece of potato tuber‚ bread crump and crisps) in different test tubes with distilled water to make a

What is urodynamic testing? Urodynamic tests are done to determine how well your lower urinary tract is working. The lower urinary tract includes your bladder and the tube that empties your bladder (urethra). When your kidneys filter your blood‚ urine is stored in your bladder until you feel the urge to pass urine (urinate). Urination requires coordination between the nerves and muscles of your bladder and urethra. When your lower urinary tract is working well‚ you should be able to: Start urinating

Introduction For the last week‚ specific tests had to be applied to determine the unknown solid that was given out randomly. Physical tests‚ solubility test‚ characteristic tests‚ NMR spectrums‚ and IR spectrums were all utilized to distinguish the identity of the solid. These assessments and a couple additional tests will be utilized again to determine the unknown liquid that was given to us in class. The other characteristics that will be looked at will be the boiling point‚ refracted index‚ and

The catalase test is used to differentiate staphylococci (catalase-positive) from streptococci (catalase-negative). The enzyme‚ catalase‚ protects the bacteria from the toxic by-products of oxygen metabolism. This enzyme is produced by bacteria that respires using oxygen. The catalase-positive bacteria include strict aerobes. Catalase-negative bacteria may be anaerobes‚ or they may be facultative anaerobes do not respire using oxygen as a terminal electron acceptor. The test reaction is very fast

Flame Tests By: Jordan Anthony‚ Zack Balog‚ and Evan Degraw Regents Chemistry class‚ Union Springs High School‚ 4th period January 19/2015 The purpose of this lab was to see what colors are characteristic of particular metallic ions in a flame test and use their characteristic color to identify other elements. Another purpose is to understand how fireworks work. This experiment will help one understand how a flame test is performed and that every metal has a unique bright

lab experiment six different test were conducted. Each test consists of chemicals to be tested using 3 to 10 drops of the additive in order to observe a change. With any experiment you compose a hypothesis; where you make an educated guess. The hypothesis will primarily be‚ which base chemical will produce the greatest change based on the additive. Experiment 6.1 (Starch) when adding the three drops of Iodine to each tube observe the color change. When performing this test the chemical with the larger

3.1 Ex-vivo Evaluation of the Mucoadhesiveness of Synbiotics Mucoadhesive properties prolong the retention time of the bead’s dose in the targeted site the colon [23]‚ [50]. Since the dose is intended to colonic release‚ mucoadhesion parameters play a key role in the efficiency of the form. The beads remain longer in contact with colonic mucosa when they have more mucoadhesive property. As a result the probiotics will have enough time to get released from beads and colonize the colon [37]‚ [51]
