Identifying Unknown Bacteria Using Biochemical and Molecular Methods Beginning of Instructor Pages Instructor Pages - - 3 Purpose The purpose of this lab is to introduce a variety of lab techniques to students working on the common problem of identifying an unknown bacterium. This lab helps students develop an understanding of the biochemical and molecular differences in bacteria and introduces the concept of identifying species based on characeristic gene sequences. Students work through

04/29/2013 G-Unknown code Gram Positive-Micrococcus luteus Gram Negative- Klebsiella pneumoniae Unknown Paper The unknown project was a very good realization of me and my partner going out by our selves. The very first day of the Unknown project I was acquainted with Denise who was very friendly and was very nice as far as assisting me in the project. The first day we were introduced too various different forms of the unknown such as broth‚ Blood agar plate‚ MSA plate

that can assist in identification of bacteria are their ecological habitats and more advanced methods such as genetic and molecular composition. Using various techniques one is able to distinguish and ultimately assign then genus and species of the unknown bacteria. Methods: Gram Staining: The Gram stain separates bacteria in two distinct classes and is also useful in distinguishing morphology. Through this technique one is able to identify bacteria as either gram positive or gram negative. The gram-negative

kill that species. For the purpose of bacteria identification‚ numerous tests have been devised to find out the exact species in question. However‚ because new strains continue to emerge‚ it is of the utmost importance that microbiologists and microbiology students understand the nature of each bacterial species and how that species creates and maintains its complex communities. Of equal

this lab was to determine the density of water and an unknown liquid. Density is defined as the mass of a substance divided by its volume. It is an intrinsive property of matter and is used to specifically characterize substances. III. Procedure: 1.We massed an empty 10mL graduated cylinder to the nearest .01g. 2.Then‚ we filled the graduated cylinder with 4.0-5.0 mL of distilled water‚ 3.massed it to the nearest 0.1 ml and 4. recorded the data. Then to determine the density of the unknown liquid;

as are their abilities to develop and adjust to altering environments. That is why it is so significant to be competent to identify microorganisms. This study was conducted by applying techniques and experiments cultured in microbiology lab for the identification of the unknown microorganism. Introduction: Identification of bacteria is significant because they are not only beneficial but potentially hazardous as well. The identification of bacteria can lead to breakthroughs in healthcare regarding

Introduction to Microbiology – Case Study 1 Kristen Alejos You are working as an emergency room nurse in Topeka when a mother brings in her 8 year old son because of severe‚ bloody diarrhea. When questioned‚ the boy said that it hurts when he goes to the bathroom and his mother said he had vomited in the previous two days. When asked about their previous movements‚ the mother and son both mentioned a backyard barbeque that had taken place 6 days earlier. The boy complained that his mother
