of an unknown microbe by observing its reactions to a barrage of chemical and physical tests. Different microorganisms react in different ways‚ due to their function‚ digestibility‚ morphology‚ chemical make-up and other details. By observing the responses to these tests performed in a particular sequence‚ some can be eliminated as possibilities and others require further investigation. Materials and Methods: A stock culture‚ labelled 25‚ was stored at room temperature (in the lab desk). A transfer

LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured

oasis of life that resides around the earth ’s nourishing thermal vents. Here‚ a vast community of organisms thrive under very harsh circumstances‚ and most importantly‚ in the absence of life-giving light. How is this possible? Chemoautotrophic microbes. Chemoautotrophic bacteria are the primary producers on the ocean floor‚ where light cannot reach. Unlike most organisms‚ these bacteria do not need carbohydrates‚ vitamins‚ protein‚ and sugar to create energy‚ and ultimately to survive. Instead

Lab #4: The Immune System Purpose: The purpose of this lab was to perform and understand the procedures of conducting an ELISA test to determine whether a particular antibody is present in a patient’s blood sample through a virtual simulation. Hypothesis: If I successfully complete this lab‚ I will then understand how to perform an ELISA test‚ the purpose an ELISA test‚ and also how to interpret the results of this test. Materials and Procedures: Materials: Howard Huges medical

Introduction: During this unknown lab report various test were performed to differentiate microbes from each other and to compare metabolic and biochemical process. The gram stain distinguishes between Gram positive and Gram negative bacteria based on the composition of the cell wall. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan

Microbes in environment and health Micro-organisms are very dangerous but they can also help you. They cure you but they can also kill you. They have been around longer than dinosaurs. They can adjust to almost any environment. There are six types of microbes. There is Archaea‚ Bacteria‚ Fungi‚ Protista‚ Viruses and Microbial mergers. Microbes play a big part in people’s health and in the environment. Good Microbes play a big part in people’s health. They mostly

Music is heard almost every place that we go- restaurants‚ grocery stores‚ the mall‚ farmer’s market‚ in the office‚ etc. Often times‚ the music is tuned out or ignored‚ but at other times‚ people get up and move to the music or sing along with it. As mentioned in the lecture‚ music is often used to fill time or space while we are doing other things such as homework‚ working or cooking. Can we fully appreciate and understand music if we are constantly occupied while listening to it? Appreciation

today’s society‚ it’s common that one would be affected by incivility in their day-to-day life. Incivility takes place with all age groups‚ and with a variety of people. Sadly‚ incivility occurs within school systems‚ workplaces‚ and pretty much everywhere else. Incivility can be from people having a bad day‚ or if one is just going through a rough patch in their life. However that doesn’t matter if your acting bitter to someone for no reason. Incivility occurs daily within the school system. Lisa

The Virtual Lab – ELISA Test Lab: Immunology 09/04/2013 Instructors: Dr. Charlie Wilson Written by: Dipen Patel I. Objective: The purpose of the lab was to learn the procedure of performing an ELISA test to determine whether a particular antibody is present in a patient’s blood sample. ELISA is an abbreviation for “Enzyme-linked Immunosorbent Assay." II. Introduction: The interaction of antigen and antibody outside the body can be used to determine if patient

Microbiology Laboratory Report Identification of Unknown Bacteria 03/10/05- 04/01/05 Authors: Richard Hendricks‚ Jessica Prebish; NMU Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques
