Rebekah Worley February 21‚ 2012 Mitchell Section 4 Biol 311 Staining and Identifying Unknown Bacteria Introduction: The microbiology lab up to this point has been used to teach the students how to stain and identify bacteria. There are several types of staining through which the bacteria can be identified based on the color and shape. The staining methods used in the lab are Gram Staining‚ Capsule Staining‚ Endospore Staining‚ and Acid Fast staining. One of the most significant method of

Both E. coli and S. epidermidis produced measurable acidic byproduct. H.What is the cellular role of catalase? The cellular role of a catalase is to enable the breakdown of hydrogen peroxide into water and molecular oxygen. I.Which of the organisms‚ if any‚ produced catalase? S. epidermidis is the organism that produced catalase. J.Which of

how to identify and classify them. Thus‚ the main purpose of this project is to identify our unknown microorganisms‚ more specifically‚ our unknown bacteria. There are many ways to distinguish and classify bacteria. You can distinguish bacteria from other microorganisms by its size. Bacteria are around one micrometer and yeast is 4-40 micrometer

smaller in size and withers. Isotonic environments are preferred by most microbes for the most advantageous growth‚ although some live in slightly hypotonic solutions. (Alonzo‚ 2008) Growth in NaCl Solutions Samples of S. cerevisiae and S. epidermidis were placed into sodium chloride (NaCl) solutions of 1‚ 7 and 15 percent which were supplied in the lab kit. The S. cerevisiae results are as follows. After 24 hours of observation there was a moderate amount of growth in the 1% NaCl solution

Antibiotic Sensitivity lab A. Define the term selectively toxic. Why is it an important feature of antimicrobial agents? Selective toxicity is the ability of a chemical or drug to kill a microorganism without harming its host. Selective toxicity is important to microbial agents because it enables these agents to inhibit or kill a microorganism by interacting with microbial functions or structures different from those of the host thereby showing little or no effect to the host.

Abstract This project was done to enhance an individual image through body scent. Past odour-related journals were analysed and found that the bacteria and mildew are the cause of the odour. Hence‚ this current study aims to investigate the effectiveness of the sunlight in removing the odour and mildew and finding alternatives in replacement of sunlight by using salt‚ vinegar and baking soda. In the experimental procedures‚ dynamo was added to five sweaty shirts. Salt‚ vinegar and baking
