Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized

any specific mineral. Well‚ “because the atomic structure of a mineral species is always the same‚ most of its physical properties are relatively constant and may be used for the mineral’s identification” (Gardiner and Wilcox 107). There are many intriguing physical properties to mineral identification. Visible properties include color‚ luster‚ streak‚ crystal form‚ cleavage. The tactile property can be measured using Mohs scale‚ which measures hardness of minerals compared to common objects

on human samples collected from different body sites. The tests are used to detect and identify any microorganisms capable of causing disease. Knowing of unknown microorganism is important on how this microorganism works and how it is structured‚ means knowing how it can affect humans. The purpose of this study was to identify an unknown bacterium by applying all methods that were previously conducted and learned in the medical microbiology laboratory class. **Materials

There is always a problem in an organization that must be resolved. There are many different types of decision making processes that an organization can use to help resolve these problems. This paper will examine some of the different types of decision making processes with examples from four organizations. This includes the decision making processes strengths and weaknesses‚ as well as comparing and contrasting them with each other. This paper will also describe how a problem can best be identified

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

Analysis of an Unknown Mixture Performed: 2/13/14 Submitted: 3/3/14 Abstract: The purpose of this experiment was to separate and identify the two unknown compounds. The sample used was 105 and it contain 2-propanol and 2-heptanone. IR spectrums were taken of the contents of the second and sixth test tubes and showed the presence of an OH functional group and a small amount of ketone in test tube two and a large presence of ketone in test tube six. The average boiling points of the test tubes

Enterobacteriaceae are gram-negative bacteria that are part of our endogenous microbial population. In normal circumstances our natural flora keeps a balance between the Enterobacteriaceae and the immune response‚ however‚ when these natural flora are destroyed infections might occur since there is no balance anymore. Immunology Our immune response can target Enterobacteriaceae in several ways. Since Enterobacteriaceae are Gram-negative bacteria‚ they have LPS in their outer membrane. LPS can activate

Autumn White 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
