One of the most common bacteria known to man is affiliated with the genus Staphylococcus. Staphylococcus aureus can be described as bacteria that present as gram positive cocci either in pairs, tetrads, short chains or irregular grape like clusters (2A). With their diameter ranging from 0.5 to 1.5 um, other characteristics that comprise this bacteria include their non-spore forming ability and nonmotile ways (2A). Defined as facultative anaerobes, these microorganisms are usually encapsulated(2A)

My research methodology consists of creating a terraform like sculpture using plaster molds and a low fired clay body. Instead of using glazes on my work I will be experimenting with plant matter for the surface treatment. The sculpture will be hollow and will be able to hold water. I will also be experimenting with firing the pieces just hot enough to allow for the water to leach out enough to keep the outer surface of the sculpture moist without the entire piece becoming so over saturated that

Conclusion: In our experiment, we were able to observe the isopods behavior. According to our hypothesis, it stated that if we divide the isopods equally in light and dark, carefully administered, the isopods will gravitate towards the darker side. The dependent variables were the isopods and their behavior whereas the independent variables were time, temperature and light. We conducted our experiment by collecting a total of 16 isopods in total and equally distributing them into two chambers that

Purpose: Gel Electrophoresis is used to separate macromolecules like DNA and RNA by their size, or proteins by their charge and size. In this experiment, I used the Gel electrophoresis to determine the presence of all dyes in a specific dyes mixture. Hypothesis: If all dyes are present in this mixture, then the dyes in the mixture should travel the same direction as the dyes in it towards the positive electrode because the negatively charged dyes travel towards the positive electrode while the positively

During the lab of testing whether the color of a pen will affect the movement of a termite, it was discovered that termites are more likely to follow a black and purple pen, rather than a red, blue, or green pen. It was hypothesized that if a blue, red, black , purple, and green pen were used, then the termite would follow the black pen because of it’s comparable scent of that of pheromones. This was proven correct based on the data and graph. Also the purple pen had pheromones in it’s scent like

Summary of “Effect of Angle on Flow-Induced Vibrations of Pinniped Vibrissae” * In the article “Effect of Angle on Flow-Induced Vibrations of Pinniped Vibrissae,” there are two types of epidermal keratinous structures which upon introduction to water flow manipulate the way the vibrissae behave: undulated and smooth. These vibrissae exist among pinnipeds: the furrowed undulated structure which exhibits among the majority of true seals (with the exception of the bearded and monk seals) and the smooth

cultures. The differential tests used to identify the unknown cultures were Gram stain, Catalase, Mannitol Salt Agar (MSA), Blood Agar, Novobiocin, Coagulase, and DNAse (Alachi, 2007). Rebekah Worley February 21, 2012 Mitchell Section 4 Biol 311 Staining and

and streaked it across a TSA plate. This was to separate the two bacteria. After two rounds of streaking, I discovered one of my bacteria was dead and had to acquire it separately from Dr. Christmann. Once my bacteria were separated, I began Gram staining. To Gram stain, I took a slide and spread each bacterium with a droplet of water onto two different slides. After heat-fixing, I stained with Crystal Violet for 1 min, rinsed with distilled water, stained with Gram Iodine for 1 minute, rinsed with

There are numerous types of bacteria that can be found in every environment. Each bacterium has different morphology which includes shape, texture and pigment production. These bacteria also have different food requirements which are important in being able to identify a microorganism. Microorganisms are a diverse group containing all bacteria a single cell prokaryotic organism that is found in every type of environment, archea single cell microorganism that lacks nuclei and almost all microorganisms

Lab Report A differential staining procedure used in microbiology is called the Gram stain. The significance of the Gram staining procedure is that it differentiates the bacteria into two groups. The Gram reaction of a bacterium adds valuable information for the treatment of disease. The Endospore stain is a special stain that is used to determine the presence of endospores in bacteria. This stain is used to detect if certain bacterium cell contain highly opposing spores within their vegetative
