There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics to other purposes such as knowing the exact microorganism has to be used to make certain foods. This experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by the lab instructor. The methods that

Salts Agar (MSA). This media contains salts that most organisms can’t tolerate due to their osmolity ranges. Microbes that normally exist under these conditions are able to grow. MSA is usually used for Staphylococcal species. Differential media provides chemical compounds that bacteria metabolize differently. The difference is observed by a colony or media color change. This media is often used to differentiate between groups of organisms with the same morphology and biochemical resemblances.

experiment is to determine the unknown DNA plasmid using restriction enzymes and conducting electrophoresis finally comparing the resulting fragments with the known restriction map. In this lab‚ it succeeds in showing the fragments. In this report we will discuss the‚ results‚ limitations and possible errors. Introduction In biology restriction enzymes are used in several ways to modify and manipulate DNA molecules. One common use is to compare pieces of DNA from one that is unknown‚ with fragments of DNA

Background: In Jane Horack’s article “Staphylococcus epidermidis”‚ S. epidermidis is described as “gram-positive cocci bacteria that are part of the normal flora on the skin and nasal passages.” The article goes on to say that the species was originally named Staphylococcus Albus by microbiologist Rosenback in 1884. When viewed under a microscope S. epidermidis will appear in chains‚ pairs‚ or grape-like clusters (Horak 1). Taxonomically‚ the species S. epidermidis falls in the genus Staphylococcus

“transferring” into you‚ then you should not be concerned about DNA from GMOs either‚”says Layla Katiraee in her article “10 Studies Proving GMOs Are Harmful”(Katiraee). More and more Americans are becoming worried about the use of Genetically Modified Organisms in their food. The controversy of the use of GMOs in food can be understood through examining how they work‚ their disadvantages‚ and their advantages. Farming has transformed so much over the years. Six thousand years ago‚ farmers had holding

to develop and adjust to altering environments. That is why it is so significant to be competent to identify microorganisms. This study was conducted by applying techniques and experiments cultured in microbiology lab for the identification of the unknown microorganism. Introduction: Identification of bacteria is significant because they are not only beneficial but potentially hazardous as well. The identification of bacteria can lead to breakthroughs in healthcare regarding treatment of old and new
