Grams staining method and reliability of this method. According to me‚ Grams staining process is a simple technique that assists in recognition of etiological agent and therefore can be called as one of the most significant staining practices in microbiology. Though‚ Gram is concerned that the staining process developed by him is imperfect because not all bacteria can be stained by it‚ but in my opinion‚ when we pour ethanol over the slide to wash away the dye then only definite bacteria can retain

Streak Plate Isolation for Obtaining Pure Cultures Data Interpretation 1- In order to unsure that you get a pure sample. 2-pure culture: laboratory culture containing a single species of organism. A pure culture is usually derived from a mixed culture (containing many species) by methods that separate the individual cells so that‚ when they multiply‚ each will form an individually distinct colony‚ which may then be used to establish new cultures with the assurance that only one type of organism

For this reason‚ it is important to test and observe unknown organisms in the lab to continually improve the health and well being of society. The objective of this report was to first isolate a single colony of an unknown culture on a LB agar plate. From here‚ a slant was made and used for multiple types of testing in order to determine the identity of the unknown organism. The tests performed to identify the unknown organism included Gram Staining‚ Fluid thioglycollate/aero-tolerance test

Determining pH Using a Red Cabbage Farnoosh Mazarei Food Microbiology April 22‚ 2011 Purpose: To test the pH level of many common household object by use of the juice from a red cabbage. Background: pH is the measure of the acidity or basicity of a solution. The pH scale ranges from 1 to 14 with 1 through 6 being acidic and 8 through 14 being basic; 7 is considered neutral. The use of the red cabbage‚ or red cabbage juice is because red cabbage can be used as an acid/base indicator

yeast and mold in a sample. It counts the number of colonies produced by a very dilute suspension of bacteria on an agar plate and to observe the differential staining behaviour of the living bacteria. This involves counting the colonies produced by viable cells under favourable growth conditions. Some techniques needed before the viable count‚ like pour plate method‚ spread plate method and most probable number method. The viable count is very specidic‚ as it represents the number of colony forming

Continental Drift‚ Plate Tectonics‚ The North American Plate The experts and scientists have theories on how the the world’s plates move and how earthquakes occur. These theories on how the world’s plate move is called continental drift and the theory on how earthquakes occur is called plate tectonics. They also have a lot of information on the North American Plate and in which direction it is moving and information like that. Now let me tell you more about each of these topics. Continental
