    Lab Report On Unknown 32

    The first test conducted on unknown bacteria 32 was the Gram stain. From this stain, unknown 32 was found to be a Gram-positive cocci. This test eliminated all possible Gram-negative bacteria, Gram-positive rods and Gram-positive spirillium. Next, the endospore test determined whether or not the Gram-positive bacteria contained endospores. With the use of malachite green, steam, and safranin it was found that unknown bacteria 32 did not contain endospores.…

    Unknown Bacteria Lab Assignment

    From the streak plate, several slides were made to determine the morphology of unknown 45. A Gram stain, used to indicate the type of cell wall possessed by the bacterium, was performed. U45 stained a bright pink color and were small ovals and rods in shape. This indicated that U45 was a gram-negative bacillus bacterium. A capsular stain was then performed to determine the presence or absence of a capsule. Unknown 45 was positive for capsules. Having determined that U45 was gram-negative, there was no need to perform the Schaeffer-Fulton endospore stain, which is used detect the presence of endospores in certain gram-positive bacteria.…

    The purpose of this experiment is to distinguish and indentify an unknown bacterium. There are several tests that can help one eliminate and narrow down the options. The most useful test, and the very first one done, is a gram stain. This test will tell whether the bacterium is gram-positive or gram-negative. After the type of gram stain is identified, the tester has a wide array of differentiating tests at their disposal. Based on the results from these tests, and the numerous others that are available, one can accurately establish the identity of an unknown bacterium.…

    Unknown Lab Report

    I think we correctly identified our unknown as P. aeruginosa because we performed several different tests, eleven of which helped us identify our organism on the Gram negative chart that was in our lab book. When it came down to narrowing the organisms down to ours, I looked at the glucose test first because all of the other Gram negative organisms were positive for glucose except for two. Since our organism tested negative for glucose it helped narrow it down to only those two organisms, Alcaligenes faecalis and Pseudomonas aeruginosa. The other tests that we performed on our unknown were not really helpful when it came to determining if it was Alcaligenes faecalis or Pseudomonas aeruginosa because they both had all the same characteristics when it came to the lactose, mannitol, motility, indole, citrate, H2S, urease, methyl red and VP tests. Our tests for lactose, mannitol, indole, urease, methyl…

    The tests performed on the unknown bacteria cultures were all used to determine the identity of the bacteria. Each of the tests performed provided some key information about the bacteria in question and how it functions. Not all of the tests were performed on every culture, however, as some of the tests were used only for gram (+) or gram (–) bacteria, while others were even more specific and used only for cocci bacteria. The tests performed and what constitutes a positive and negative test are as follows.…

    Gram Staining Lab

    Prokaryotes are a large group of organisms with no membrane bound organelles. They consist of two domains: Archaea and Bacteria. These organisms are only found in extreme environments such as volcanoes. Prokaryotes are still being researched and are a very diverse group. In this lab we focused on trying to identify if the bacteria found had a lot of peptidoglycan by gram staining. Testing this could be done by using a Petri dish full of agar and testing different bacteria on it to see if the bacteria obtained is gram positive or gram negative. My hypothesis is there will be a lot of bacterial growth on all of the plate.…

    Bacteria Ecology

    To identify the resulting colonies a procedure called gram stain is used in the identification of bacteria. Bacteria can be gram-positive, gram-negative, or gram-variable. Most bacteria however, are usually gram-positive or gram-negative. Gram-positive and gram-negative bacteria react differently to staining because of the differences in their cell walls. Bacterial cell walls contain a polymer called peptidoglycan. Gram-positive bacteria have more of this polymer than gram-negative bacteria. They are also less complex than gram-negative cell walls, missing different polysaccharides, lipids, and proteins that are found in gram-negative bacteria. Three different stain types are used in the identification process: safranin (pink/red), crystal violet (purple), and Gram iodine. Along with being either gram-positive or gram-negative, most bacterial cells can be classified according to three shapes: bacilli (rods), cocci (spheres), and spirilla (spirals, or corkscrews).…
