forms of microorganisms are on the rise. The importance of identifying these pathogens and their related epidemiology has become increasingly more important. The purpose of this study was to identify an unknown bacterium in a controlled laboratory environment over a 5 week period. Utilizing a variety of differential testing and staining methods learned in the microbiology course‚ students were to determine the identity of an assigned unknown organism. Observations were made and recorded each week

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

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

the identity of the metal is paramount to determining what conditions to use the metal under. This seemly simple task is‚ however‚ can be quite complex‚ as there are many ways by which one can identify a metal‚ each with varying amounts of accuracy. In order to test some of these methods‚ thermal expansion‚ density‚ and specific heat were used to identify two small metal rods. The overall purpose of this experiment was to identify an unknown metal using the three previously stated properties.

Objective: To successfully separate and identify all three unknown cations‚ found in a mixture and belonging to one of two specific groups (2 from one and 1 from the other). In order to do this we will be using various tests and reactions and observing the effect they had on our solution.

Carlie Haeffner Qualitative Analysis March 20‚ 2015 The purpose of this lab is to identify unknown ions in a solution by using a type of chemical reaction called precipitate reactions. The key to finding which ions are present in a solution is to form a precipitate which makes the ions “come out” in a reaction (McNeil‚ 2013-2014). Water is used in these experiments to act as a solvent. Since water is a polar molecule‚ the slightly positive and negative charges will sometimes pull apart molecules

What’s the Benefit? (The Report) “It is easier to stay out than get out”.- Mark Twain. Smokers believed that smoking is like heaven that releases all your stress and problems furthermore only smokers can understand their fellow smokers. For all over the years the consumption of cigarettes increases and the government must do something about that. Taxation is one of the methods of the government in which they finance their expenditures by implementing charges on citizens and corporate entities

Thermus aquaticus Thermus aquaticus is a species of bacterium that can live in high temperatures‚ ths species is one of thermophilic bacteria that belong to the Deinococcus-Thermus group. Thermus aquaticus appears as either a rod or a short slender thread‚ and the rod-shaped cells will tend to form either a rose shape or a straight line pattern. When exposed to sunlight‚ Thermus aquaticus can be a yellow‚ pink‚ or red color due to pigments within the bacteria. Along with the coloration
