| Gram Negative Unknown | Biology 3444-006 | | Lena Wallace | 11/7/2011 | | Abstract: The purpose of this lab was to identify an unknown bacteria culture using differential tests. The identification of the unknown culture was accomplished by identifying the bacteria based on its specific metabolic characteristics and morphology. It is suggested that culture 11 is a sample of Enterobacter aerogenes. Introduction: This experiment was centered on metabolic and biochemical testing

Microbiology UNKNOWN LAB REPORT Kateryna Petrakova INTRODUCTION Microorganisms cause a great amount of diseases. For healthcare providers it is very important to be aware of what organisms are pathogenic and cause a disease and‚ therefore‚ to find an appropriate treatment. Different microorganisms require various environments in order to replicate and to become dangerous for a person’s health. An integral part of any medical treatment is to be able to recognize and

Labset Four Worksheet 1. Define the term “selectively toxic.” Why is it an important feature of antimicrobial agents? A substance or drug is selectively toxic if the agent used in it is able to kill the microorganism that it is meant to without harm to the host that has taken the drug. This is very important to microbial agents in that it enables these agents to inhibit a microorganism by interacting with microbial functions or structures different from those of the host; thereby showing little

Purpose: Unknown mixtures will be separated by means of chromatography in which the mixture will be passed in a solution through a medium leaving behind components of the mixture at different rates‚ therefore‚ different spots on the absorbing substance. This will help determine the identity of unknown mixtures. The spot colors on the strip of filter paper and the Rf values of the unknown samples will be compared to those of known samples. To find the position of the spots on the strip of paper‚ we

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. This eliminated Gram-positive cocci Sporosarcina

Abstract The primary focus of this lab was on microscopy and simple stains. Crystal violet and Carbol fuchsine‚ simple staining components‚ were used to stain the slide in order to see the different microbes in order to determine their cellular shape and identify unknown ones by comparing. Introduction Bacterial cells are usually colorless because cytoplasm‚ for the most part‚ is transparent. Since the bacteria are colorless‚ it is almost essential to add a stain to make the bacteria more visible

Margaret E Gibson July 20‚ 2009 Microbiology Dr. Metera Lab Report 3: Labs 7 and 8- Metabolism and Biochemical Tests Abstract This experiment focused on metabolism and biochemical tests. The goal of performing these tests was to differentiate microbes from one another and to compare how metabolic and biochemical processes differ from species to species. The tests performed include: the Fermentation of Sugars Test (sucrose‚ glucose‚ and lactose)‚ the Urease Test‚ the Fermentation
