Pseudomonas taiwanensis – Enrichment‚ Isolation and Identification Microbiology 521 2/10/12 Purpose: The purpose of this experiment was to enrich Pseudomonas bacteria‚ isolating a species of Pseudomonas and identifying it using phenotypic properties and DNA sequencing as an existent or completely new and undiscovered species of Pseudomonas. Overview: Genus Pseudomonas is a chemoheterotrophic bacteria found in soil and water. They are Gram negative‚ motile‚ paired rods that are also oxidase-positive

reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic

Purpose: To identify an unknown bacterial specimen using basic laboratory technique and biochemical tests. The unknown bacteria will be one of the following: Enterococcus faecalis‚ Staphylococcus saprophyticus‚ Escherichia coli‚ Enterobacter aerogenes‚ Proteus vulgaris‚ Salmonella [I assume typhimurium]‚ or Shigella [either flexneri or sonnei‚ we used both in our lab during the semester]. Procedure {and observations}: Observe bacterial colony morphology. {Colonies are large‚ beige or

is involved with the cannon being fired then the force of gravity would cause the cannon to start to slow down‚ wouldn’t go as far and the direction or trajectory of the cannon ball would be a curved line going down. Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground &

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized

gas vesicles in the mutant strain made the colonies a red color. The wild type strain (NRC-1) had gas vesicles and appeared a pink pigment color. Growth on the agar allowed one to examine the specific colonies. Inoculation and growth in the liquid culture were done to examine both strains of Halobacteria in the aqueous solutions. DNA extraction was done to take DNA from the Halobacteria strains and examine their genotypes. The PCR reaction’s purpose was to locate specific
