Phelps‚ Biology 205 MW 2:10pm. Unknown Organism Paper The unknown organism tested in the Mesa lab was collected from in between the toes of my puppy‚ Riley. The original culture grown consisted of dozens of visibly different organisms of varying colony colors and growth patterns. I chose to test a smaller‚ red colony for my experiments. Based on its gram reaction and oxygen requirements‚ the following tests were performed to reach my presumptive ID: Test Performed Result Gram Stain +

-Unknown Mixtures Lab- Purpose: The aim of this experiment was to find out the two substances of the unknown mixture from salt‚ sugar‚ dirt‚ and baking soda by looking at its properties. Hypothesis: Find the unknown substance by testing it out by heating it‚ pouring water‚ vinegar‚ and observing it . Procedure: 1) Materials- * 100ml of water * Vinegar * Bunsen Burner * 2 beakers * 1 spatula 2) First‚ do steps (3-6)to find out the properties of salt‚ sugar

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

Increasing Fiber in Rice Pilaf Arcelay‚ Marilyn March 30‚ 2007 FOS 4041L Dr. Dixon Introduction Obesity is a word that everyone is currently familiar with. The media and health professionals have been working tirelessly to make the general public aware of its prevalence and detriments to society. With the staggering statistics of 32.2% prevalence in adults and a range of 13.9% to 18.9% prevalence in children and adolescents‚ these outstanding numbers stand

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

BACTERIA Period: 4 Characteristics: 3 major shapes Cocci Basilli Spirilla 3 major components Mesosomes flagella Plasmids Growing Up: Bacteria can obtain energy through phototrophs(sunlight)‚ lithotrophs(inorganic compounds)‚ and organotrophs(organic compounds) Marriage/Reproduction Binary Fission: The process by which all bacteria reproduce. It results in the separation of a single cell into two. Transformation: genetic alteration

Lab 11 Methodology By using aseptic‚ a little cultured bacteria was inoculated on the TSA agar. A quadric streak was making. Inoculation loop was heated and keep it cold for a while before the next quadratic streak. Six agar plates were observed for 24 hour at temperature of 30ºC. Choose one from the dense colony and make a sub-culture on the new agar plate. The step was repeated to get a single colony‚ which is pure colony. a) Sequestration of bacteria from fish organs Methodology

Title: Observing Bacteria and Blood- Lab #1 Purpose: Being able to learn how to correctly use a microscope and the oil immersion lens to be able to see the prepared slides. Also to learn how to prepare my own yogurt and blood slides. Procedure: First‚ set up the microscope. Clean the ocular lenses and objectives with lens paper. Then pace the prepared e slide on the stage and make adjustments. Turn the rotating nosepiece until the 10x objective is above the ring of light coming through the slide

Glowing Bacteria Lab Introduction- 1. Transformation involves the transfer of genetic information into a cell by directly taking up foreign DNA from its surroundings. This DNA is then incorporated into the host cell’s own DNA. This transformation usually occurs within plasmids‚ small circular DNA molecules separate from its chromosome. After the recipient cell is infected with the DNA‚ the cell will move on with replication‚ producing offspring with traits encoded by the plasmid. These plasmids

The purpose of this lab is to isolate a bacterial population from the normal throat flora. A streak plate method will be used to obtain a pure culture of a Gram positive coccus genus of bacteria. Several biochemical tests will be performed to aid in the identification of this unknown bacterium. Biochemical tests are a series of tests used to identify certain bacterium The various tests that are used in this lab are the catalase test‚ oxidase test‚ blood hemolytic test‚ MSA‚ blood agar‚ and PEA/ab
