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 objective of this project was to identify an unknown bacterium through several differential tests. Identifying an organism can be very beneficial in the field of medicine. Knowing what an organism is can indicate its pathology and treatment. These tests are designed to find out about an organism’s metabolism and other various characteristics. For this project, ten…
Material & Methods 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 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.…
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.…
Introduction 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.…
Name: Danielle Title: Unknown Lab Report Introduction: 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.…
Introduction: Being able to identify a particular bacterial species is important. It is very useful in knowing its risk of toxicity to humans or animals, its resistance or susceptibility to antibiotics, and determining how to control its growth or kill it altogether. The purpose of these procedures is to discovery the identity of an unknown microbe by observing its reactions to a barrage of chemical and physical tests. Different microorganisms react in different ways, due to their function, digestibility, morphology, chemical make-up and other details. By observing the responses to these tests performed in a particular sequence, some can be eliminated as possibilities and others require further investigation.…
The purpose of the following study is to determine where the two unknown bacteria acquired in Microbiology lab should be classified in regards to temperature, pH level, and osmoregularity. It is important to classify bacteria in order to identify them. Identification of bacteria is important because they are not only useful but potentially dangerous as well. The identification of bacteria can lead to breakthroughs in healthcare regarding treatment of old and new diseases alike. Identifying bacteria can also be used in many other areas from better crop production through microbial pesticides to biological warfare. Their uses are endless as are their abilities to evolve and adapt to changing environments. That is why it is so important to be able to identify microorganisms. This study was conducted using techniques and experiments learned in microbiology lab that were used to classify the two unknown bacteria.…
1. Title: Double unknown identification of a mixed culture of Gram-negative and Gram-positive bacteria 2. Author:…
Introduction When applying biology to real world cases, it takes numerous tests to be able to identify exactly what a type of bacteria an unidentified bacterium is, whether it is a bacterium that is causing a person to be ill or a bacterium that is being studied in a laboratory. Often times a bacteria is taken from a contaminated sample that may contain more than one type of bacteria and therefore the specific bacteria that is to be identified has to be isolated. This can often be done by streaking the sample to single colonies. The individual colonies can then be put through several different tests that allow one to identify distinctive aspects of the bacteria. Some examples of these tests are a gram-stain and an API test. These tests allow one to figure out what properties a bacteria strain contains, such as gram negative or gram positive with the gram staining test, or what bacteria an unknown is based on positives and negative of the API test. The results of API tests, will show extremely accurately what a bacteria is based on previous tests performed. One such bacteria than can be identified is Salmonella choleraesuis. There have been many…
Introduction The purpose of this project was to detect which organism we had in our unknown mixed culture tube by running a series of experiments to detect which specific Gram negative organism we had. To detect your gram positive from the mixed culture was given as extra credit points also. A Gram stain was performed and isolation streak plate in order to isolate and observe the unknown organism. Before the series of test, a dichotomous key had to be written up in order to know what steps and tests to run to identify the unknown Gram negative organism. I had to run three experiments in all before I identified my unknown. Identifying unknown organisms is really important, one reason is because it produces benefits for many aspects of…
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…

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.…
