Requirements for Unknown Report You have been provided a mixed culture (a gram positive and a gram negative) from which you should have isolated each type of organism‚ described their colonies on a TSA plate‚ and described their cellular morphology. You were graded on this activity separately. After you have isolated your gram negative in pure culture you will be subjecting it to various biochemical tests and making observations about the cells‚ colonies‚ growth temperature preferences‚ etc. in

explained through science. I have always been fascinated to know how things work and why or how they happen. That is why microbiology is perfect for me. I like finding out how or why something can happen and I can do that if I go into the field of science. I have been looking into colleges and professions recently and I have become very interested in microbiology. Microbiology is the study of microorganisms. Microbiologists try to understand the organisms and how they interact with their

report required the successful identification of two unknown substances through experimental testing on a selective collection of materials and equipment. For the first substance (which will be either tin or aluminium)‚ two tests shall be done to ensure a decisive and educated decision onto what the substance is. The first step utilizes the dramatic difference in density between the two substances by measuring the volume and mass of the unknown substance. By calculating the volume (through displacement

Identification and Diagnosis of Unknown Enteric Bacteria in an Infected Patient Using an Enteropluritube Brooke Addario 2/16/2015 BIO 488C - Section J TA – Jacob Karsten Introduction: Enteric bacteria are members of the Enterobacteriaceae family of microorganisms. These gram negative‚ rod shaped‚ facultative anaerobes are found in the intestinal tracts of humans and animals. Enteric bacteria can be pathogenic; however‚ they are also a normal part of human bacterial flora and are therefore

I. Title Identification of an Unknown Plasmid In this experiment‚ we determined the phenotypic capability of an unknown plasmid along with its size. With the use of gel electrophoresis‚ we analyzed the gel photograph by using a standard DNA marker‚ Lambda HindIII‚ and came to a conclusion based on our results. II. Abstract Two experiments were done to identify an unknown plasmid. The success of these experiments came from the use of modern day technology involving gel electrophoresis

Major concepts to review for Exam 1: 1.) know the elements of life – and how the reduction and oxidative of some of these drive bioenergetics 2.) Know the general time line for biology and evolution on the Earth; What major events altered evolution especially in terms of microbially driven changes 3.) Carl Woese – what did he contribute? What kind of biological molecules are best to generate phylogenetic trees‚ and why? How does this compare to enzymes? 4.) What defines a species (formal definitions)

The unknown bacteria A and bacteria B have to be identified by its genus and species. First both bacteria had to be inoculated into a TSA agar media using the streak plate method. Four quadrants were drawn‚ so that the bacteria could be isolated as much as possible. Each bacteria was inoculated into two different plates‚ so that one could be incubated at 37 degrees Celsius and the other at 25 degrees Celsius. Bacteria B‚ which was incubated at room temperature showed red colonies throughout its media

One of the most well known area visited of Arlington National Cemetery is the Tomb of the Unknowns. Many of the soldiers buried at the Tomb of the Unknowns fought in World War One. Additionally‚ millions of soldiers had died during the first World War and many American soldiers were brought home from the European battlefields and many others’ were never identified. On October 21‚ 1921‚ four coffins were dug up from the four American military cemeteries‚ which were located in France. Corporal
