BioMi 2911 Spring 2014 RUBRIC FOR DESIGNING YOUR OWN EXPERIMENT: EXPERIMENTAL DESIGN AND MINI-PUBLICATION PART 1: EXPERIMENTAL DESIGN Many studies have shown that students learn much about how science is carried out by designing inquiry-based labs. With this in mind‚ a few times during this semester‚ we will ask you to work with your bench mates to design an experiment that will test a given hypothesis—first‚ about Koch’s Postulates‚ then about tracking bacteria in the environment.

clusters and produces catalase‚ which catalyzes hydrogen peroxide to water and oxygen. It contains a cell wall structure (including peptidoglycan and teichoic acid) and a low G + C content of DNA between 30-40 mol %. (Bauman‚ R.‚ & Masuoka‚ E. (2015).

Most are harmless and reside on the skin

Introduction Gram staining was developed by Christian Gram in the 1800’s‚ a Danish bacteriologist. (Smith and Hussey‚ 2005) It was the first differential staining technique and most common used in microbiology. Furthermore‚ bacteria are transparent and cannot be seen through the microscope. For that reason‚ Gram staining is an important tool for distinguishing between two main types of bacteria Gram-positive and Gram-negative. The Gram stain differentiates the Gram positive and gram-negative on

Gram Negative Unknown Lab Report Abstract The Unknown Gram Negative bacterium inoculated in a Tryptic Soy broth medium was randomly selected from a group of other unknowns. In order to identify this unknown the seven different types of biochemical tests will be conducted on this unknown bacterium to identify it out of 6 possible bacteria; Escherichia coli(E. coli)‚ Enterobacter aerogenes (E.aerogenes)‚ Klebsiella pneumoniae (K.pneumoniae)‚ Proteus mirabilis(P.miranilis)‚ Pseudomonas aeruginosa(P

Weekly iLab iLab: Bacterial Growth and Controlling Bacterial Growth Scenario/Summary: This week’s experiment focuses on bacterial growth and methods to control bacterial growth. This week’s experiment will be conducted in two parts: Experiment I: Growth Media and Patterns of Growth and Experiment II: Controlling Microbial Growth. Experiment I: Growth Media and Patterns of Growth. In part I of this week’s experiment‚ you will explore the characteristics of several types of growth media. For example

Fleming‚ a young Scottish research scientist with a profitable side practice treating the syphilis infections of prominent London artists‚ was pursuing his pet theory--that his own nasal mucus had antibacterial effects--when he left a culture plate smeared with Staphylococcus bacteria on his lab bench while he went on a two-week holiday. When he returned‚ he noticed a clear halo surrounding the yellow-green growth of a mold that had accidentally contaminated the plate. Unknown to him‚ a spore of

TITLE OF PROJECT: Effects of Chemoattractants of Pseudomonas Aeruginosa Through a Capillary Tube. PROPOSED COST: $1764.90 ABSTRACT: This project will show how strong certain bacteria that are commonly found in biofilms attract to Pseudomonas aeruginosa through a capillary tube. It will test ten bacteria to see which bacteria have more chemoattractants with Pseudomonas aeruginosa . These bacteria are all motile‚ so to come together to form a biofilm‚ they must lose their ways of
