Unknown Bacteria Lab Report Introduction The purpose to this lab was to identify an unknown bacteria from a mixed culture provided to us by our instructor. This study was done by applying all of the methods that have been instructed on thus far in microbiology laboratory class. Each test performed‚ provided us with some key information about the unknown organism in question and how the bacteria function. Over a two week period‚ eight prepared types of test media were provided to identify

The science of microbiology is all about microorganisms‚ what they do and how they work. Microorganisms are ubiquitous‚ and are a very important part of life everywhere since they have been around for billions of years. The two main themes associated with microbiology are (1) having an understanding of the nature and function of the microbial world‚ and (2) being able to apply that understanding of the microbial world so that the benefits to the Earth and humans are known(6). This lab specifically

UNKNOWN LAB REPORT UNKNOWN NUMBER 54 Ron Williams 7-28-05 Bio 205 Prof. Curlee Fall 2005 Purpose There are many reasons for knowing the identity of microorganisms. The reasons range from the 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 have been learned so far in the microbiology laboratory

Unknown Lab Report Microbiology Unknown A Sonia Kabra November 26‚ 2014 Introduction There are numerous reasons for identifying unknown bacteria. Some of these organisms have distinct qualities that set them apart from one another‚ such as the exposure to certain environments. Through out the semester in the laboratory‚ we are able to encounter some of the few microorganisms that we as humans have come into contact with. With the knowledge gained from the sessions in the laboratory‚ we can now

many ways we can differentiate the different species. Looking at these bacterium underneath the microscope is an important step to determine which kind of species it is. All cocci bacteria are not gram positive‚ but this lab will examine only this kind because of their influence in human health. Staphylococcus Aureus is a gram-positive coccus bacterium found in humans. It is frequently found on the mucus membrane in the nasal cavity and on the skin. It also infects many people in the hospital‚ also

Judson Cotterman III 4/6/2012 Section 185-35L Assignment #3 Gram-positive Pathogenic Cocci Discussion My original hypothesis for the individually collected throat culture on Blood Agar Plates‚ that it would show a mixture of alpha‚ beta‚ and gamma hemolysis‚ was based on the results of the class control samples of S. pneumonia‚ S. aureas and S. epidermis. In these controls S. pneumonia shows alpha and beta hemolysis while S. aureas and S. epidermis showed beta and gamma hemolysis respectively.

Biology 258-05 November 26‚ 2012 Unknown #19 Enterbacteriaceae Enterobacter aerogenes ABSTRACT The objective of this report was to identify an unknown microorganism through several differential media tests. Over the course of a couple weeks‚ ten tests were performed. First‚ a gram stain was performed‚ indicating the bacterium was gram negative. An aerotolerance test determined that the bacterium was a facultative anaerobe. Next‚ a negative result in the methyl red test

Unknown Lab Report April 25th‚ 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures
