Name: Danielle Title: Unknown Lab Report Introduction: There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics. The experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by Dr. Honer. The appropriate tests were prepared and applied. The

Microorganisms can be prokaryotic—the bacteria or eukaryotic—the algae‚ protozoa or fungi. While viruses are acellular they are also studied in the scope of microbiology because they are small and because they infect cells. While most bacterial are unicellular they can also exist in colonial or multicellular forms. In this laboratory exercise you will examine the ubiquity and diversity of various microbes that are present in the environment or inhabit the human body. Most bacteria that inhabit the body are

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

Mutated strains of E. coli were placed in four test tubes‚ each containing a different substance (lactose‚ glucose‚ water and lactose and glucose)

Isolation of Bacteria in our Physical Environment Introduction: The purpose of the lab is to apply what has been learned so far in Microbiology‚ and use it to collect and examine microbial species from the physical environment. The physical environment around the lab will be utilized to find out the variety of different microbial species growing in and around the lab. This investigation will help in preparation for the individual projects that will be done at the end of the semester. Materials

Introduction This lab is purposed to familiarize basic equipment and techniques used in the study of microorganisms. In addition‚ learn some basic techniques used in identifying prokaryotes and make and view microscope slides of some common prokaryotes. In this lab ‚ I worked two experiments ‚ the first one is cultivation bacteria "colony "‚ and When microorganisms are cultivated in the laboratory‚ a growth environment

Respiratory complication is one of the common causes of death‚ and my grandfather passed away from aspiration pneumonia couple years ago. Although we inadvertently breath air for granted‚ I observed many patients who had a difficulty breathing like my grandfather while shadowing a physician in ICU. Some of them had a lung surgery‚ while others were able to recover from a minimally invasive procedure using bronchoscopy. Certainly‚ my interest towards this field might change as I encounter new physicians

Background: Bacteria is a prokaryotic cell that reproduces using the process of binary fission. Binary fission is “The process in which a parent cell splits into two daughter cells of approximately equal size”(northwestern.edu). The reproduction of bacteria can be stopped using antimicrobials. Antimicrobials were created and are used “to destroy disease-causing microbes”(cdc.gov). That means that antimicrobials fight and destroy organism such as bacteria. We use antimicrobials to clean are house

EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by
