Determining an Unknown Through Deferential Stains and Biochemical Tests Introduction There are many reasons for knowing the identity of microorganisms. The reasons range from knowing the causative agent of a disease in a patient‚ so as to know how it can be treated‚ to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification

The Growth of Bacteria Influenced by Different Antibiotics Introduction: Plants are made up of three basic kinds of tissue that help it carry out basic functions that are necessary to maintain life and proper photosynthesis. The first and outermost layer of tissue is called the dermal layer. This is the plant’s ‘skin’ and serves the plant mainly as a source of protection. Also present in the dermal layer of the leaves are stomata‚ which are tiny openings that allow carbon dioxide to enter

To detect your gram positive from the mixed culture was given as extra credit points also. A Gram stain was performed and isolation streak plate in order to isolate and observe the unknown organism. Before the series of test‚ a dichotomous key had to be written up in order to know what steps and tests to run to identify the unknown Gram negative organism. I

Identifying an Unknown Aldehyde or Ketone Introduction The purpose of this lab is to identify an unknown aldehyde or ketone substance using chemical tests. The chemical tests used in this experiment are solubility‚ Schiff‚ Bisulfite‚ and Iodoform tests. Also‚ a 2‚4-dinitrophenylhydrazone derivative synthesis reaction will be completed from which a melting point will be obtained. The chemical test results and the melting point analysis will be compared to the table of compounds given to find the

Isolation of Unknown: 71 mL of boiling H2O were poured int an Erlenmeyer flask with 0.93 g of unknown to dissolve it. After reaching room temperature‚ the flask was placed into a bucket with ice and DI H2O. The unknown was collected by vacuum filtration‚ rinsed with ice water‚ and dried to constant mass at 0.72 g. 13C NMR (100.13 MHz‚ acetone-D6): σ 15.5 (s‚ Me)‚ 24.3 (s‚ Me)‚ 29.9 (s‚ Me)‚ 30.1 (s‚ Me)‚ 30.3 (s‚ Me)‚ 30.5 (s‚ Me)‚ 30.7 (s‚ Me)‚ 30.9 (s‚ Me)‚ 31.1 (s‚ Me)‚ 64.7 (s‚ Me)‚ 115.7 (s‚ C=C)

Determine the concentration of an unknown copper (II) sulfate solution by using colorimeter Introduction: The concentration of the solution also alterations the proximity of the solution. For example‚ the more focused concentration will frame to be denser than more weakened concentration of copper (ii) sulfate. This implies there is a connection between the concentration of an solution and its absorbance. Along these lines‚ this test is set up to discover the kind of connection between the concentration
