The purpose of this experiment was to isolate two unknown bacteria and perform a series of selective and differential tests to correctly identify each. After the bacteria was isolated a series of differential and selective tests following the dichotomous key attached were used to identify each bacteria. The Gram-positive bacteria were identified as Staphylococcus aureus with a positive confirmatory test, mannitol salt agar, showing consistent results as well for S. aureus. The Gram-negative bacteria were Pseudomonas aeruginosa with a positive confirmatory…
The purpose of the unknown bacteria lab assignment was to select an unknown bacteria culture and, through a series of metabolic tests, identify which bacteria genus resided in the pure culture received. A nutrient broth inoculated with bacterial culture (numbered 45, henceforth referenced as U45) was selected and a streak plate was made to isolate a pure culture for use throughout the assignment.…
By doing these tests we will be able to see how the unknown bacteria reacts to certain conditions. If our results of these lab experiments are conclusive then we should be able to determine what our unknown bacteria is.…
The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria can help treat a patient by knowing the contributing source of a disease. Also, knowledge of different bacteria helped others make antibiotics that are used today.…
The tests performed on the unknown bacteria cultures were all used to determine the identity of the bacteria. Each of the tests performed provided some key information about the bacteria in question and how it functions. Not all of the tests were performed on every culture, however, as some of the tests were used only for gram (+) or gram () bacteria, while others were even more specific and used only for cocci bacteria. The tests performed and what constitutes a positive and negative test are as follows.…
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. The experiment was done by applying methods in order to identify an unknown bacterium.…
There are many types of microorganisms and ways to treat each one. Knowing the differences of each is vital to treat a patient correctly. The purpose of this report is to explain the process and steps used to identify a certain microorganism referred to as the unknown.…
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 antibiotics. This study 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.…
A grinding machine uses an abrasive wheel as a cutting tool to shape or change the dimensions of a hard material. The type of materials that need grinding are usually metallic items such as tools and rods. These machines generally work by reducing the material through abrasion. Grinding is used to finish workpieces that must show high surface quality and high accuracy of shape and dimension. There are several main parts in this machine. These parts are shown as below.…

“Thinking is easy, acting is difficult, and put one’s thoughts into action is the most difficult thing in the world.” Johann Wolfgang von Goethe (German Playwright, Poet, Novelist and Dramatist. 1749-1832)…
Now more than ever, students are choosing community colleges over universities. And it is one of the smartest choices a student can make. I chose Jefferson Davis Community College because I know that it is for the best, that it will help me in my education pursuits. Not only is Jefferson Davis affordable, but it is also proven that the smaller class sizes leads to better grades, and the flexibility is great too.…
For that reason, the in progress practice for preventing microbial illness largely depends on the careful control of different kinds of pathogenic bacteria in food and water safety as well as environmental monitoring. In the food processing sectors, the biotechnology are targeting the selection as well as the enhancement of microorganisms with the goal of enhancing the process control, yield as well as efficiency and also the safety, quality and consistency of bioprocesses food products. Microbe also known as microorganisms are generic terms for the group of living organisms that…

Reports are a principal means by which members of an organisation communicate with each other about a variety of job-related matters. Reports usually go up the organisational hierarchy and recipients use them to make decisions. These reports are sometimes the source of information that becomes part of a new report that is sent on to higher management. They are the flow of information that often functions as the basis for decision making and problem-solving.…
