140 Matthew Tuthill Unknown Lab Report Introduction There are many reasons for knowing the identity of microorganisms. The reasons range from knowing the causative agent of a disease in a patient‚ so as to know how it can be treated‚ to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that I have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium. The purpose

Committee: UNICEF Topic: Child Soldiers Name: Topic Background: Throughout history children have been seen to have the most adaptable compatibility‚ especially during wartime. At an early age children can be trained to kill and do despicable things. This is because children have one barrier against these recruiters and that would be their family member. Once this barrier is gone‚ recruiters can easily cheery pick these children‚ and make them work for them and do terrible things. Now

“A Soldiers Thoughts” Zachary Scott-Singley wrote an essay called “A Soldiers Thoughts”. His essay was based on his inner thoughts and questions‚ how he should and shouldn’t feel about war. Is war right or wrong? Are these people truly the enemy? What would you do to stay alive? I feel war leaves these questions open to discussion and defiantly can change based on the person and the involvement; but the work of war can change a person’s values and morals. War‚ is it right or wrong? This question

NTRODUCTION Often in the study of microbiology‚ the need to identify an unknown microbe may arise. This aids in the recognition of which microbes are harmful or pathogenic as well as those that may be beneficial to us in some way. This report will detail how a similar project was performed in order to identify two unknown micobes using the techniques that were learnt during the course of the semester. We embarked on the project with the knowledge that we would have to identify a Gram(+) as well

Antony R 9:00Am-11Am Unknown Number 94 Unknown Results Streptococcus salivarius The first step in my unknown identification was to carry out a gram stain to observe the cell shape and arrangement. My unknown turned out to be gram positive bacteria cocci shaped with long chain cell arrangement. The unknown was gram positive because the cells stained blue-violet ‚this indicate that my unknown has ability to retain crystal violet-iodine after alcohol application on the cells which is a gram

Identification of Unknown Report Abstract: The purpose of this lab was to determine the identity of an unknown bacteria slant culture. The unknown was identified using differential tests to determine its metabolic and morphology characteristics. Results from the differential tests indicated that unknown culture 5 is Staphylococcus aureus. Introduction: The purpose of this lab was to determine the identity of an unknown bacteria slant culture using a series of differential tests. The tests

The purpose of Module 11A was to test for the presence or absence of a particular set of functional groups through the use of wet chemical tests. In this manner‚ Unknown A which was a colorless solution‚ was first tested with 2‚4-DNP which after mixing for a few seconds formed a bright yellow precipitate. Although this confirms the presence of either a ketone or aldehyde group‚ one simple chemical test does not completely specify the presence or absence of other functional groups. Therefore‚ a second

Unknown Microorganisms May 1‚ 2013 This paper is based on an experiment done in the laboratory over a period of time using the standard method of identifying an unknown microorganism relying on features such as morphology‚ arrangements and biochemical reactions. It was done in succession with each step complimenting the other. At the end of the experiment three microorganisms Bacillus azotoformans‚ Staphylococcus aureus‚ and Escherichia coli was identified and one result was inconclusive. The
