tests in order to differentiate and identify the microbes. These experiment were carried out over the course of five days in a microbiology lab. Isolation of two microbes for a pure culture of each was achieved by the streak plate method, and gram staining identified a gram-positive (+) microbe and a gram-negative (-) microbe. A blood agar plate was inoculated with the gram (+) microbe to reveal it was beta hemolysis. A catalase test was then preformed on the gram (+) microbe and

A 10-Fold Dilution Series process was necessary to examine the bacteria further. The materials needed included: one Bunsen burner, one inoculation loop, one BIC ® Multi-Purpose lighter, three sterile LB Agar Petri dishes, one bottle of sterile saline solution, one pipette gun, one canister full of sterile glass pipettes, a medium sized test tube track, and one plastic tub of medium glass test tubes. Next, one participant’s 10-Fold Dilution series was performed and three lines of ten medium test tubes

Purpose: To understand the difference between Gram positive and Gram negative bacteria. We also used this lab to examine our mixed culture, which had been Gram stained, under the microscope. Theory and background The bacterial cell wall is the outer layer of the cell that aids in structural support and protection from the outside environment. Bacteria can be identified by the structure of their cell wall and classified into two groups known to have different cell wall types. Two of these types

affect teeth staining? It’s important to know this because it relates to something common in our daily lives, our teeth. Also, knowing there are people that drink cola on the regular, it is best for them to be aware of how of much it harms their teeth. Understanding how the ph of colas affect teeth staining will help determine what colas should be avoided to keep teeth in best conditions. For this experiment, the hypothesis is the following; the lower the ph of the cola is, the more staining will be present

The first patient, 18 year old female presented with symptoms of high fever, vomiting, diarrhoea, myalgia, hypotension and signs of septic shock. In order to identify possible bacteria responsible for these symptoms, a vaginal swab was sampled, incubated on agar overnight and stored at 4C, after which they were examined throughout a series of microbiological tests. The initial culturing of the sample on nutrient agar indicated two organisms were present, and hence these were analysed individually

We all know that there are foods out there that stain our teeth, but are there foods out there that can whiten our teeth. There are foods out there that can help whiten our teeth naturally. Once you know what foods can help whiten teeth you can add more of them to you diet to enhance your pearly whites. Strawberries Fresh juicy strawberries taste great and they go great with any meal. Add them to your cereal for a juicy burst of color and taste. Strawberries actually have malic acid in them. The

Identifying the Unknown Bacteria: Bacillus cereus Brittany Moy Coastline Community College Abstract Bacillus cereus is a Gram-positive, facultative aerobic, spore-forming, rod-shaped bacterium that is widely distributed among the environment. Introduction The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria
