Biology The Unknown Bacteria - 964 Words

An unknown bacterium 15 was awarded and labeled at the table ready to be identified. Using the skills and test that are taught and learned in microbiology were applied into learning what the unknown bacteria culture was. There were multiple procedures and test done in order to gain all the information needed to determine which bacteria was given. In order to find what the bacteria was the first step was finding the right environment and temperature that would allow the bacteria to thrive and grow. Determining this is one of the most important steps in being able to obtain conclusive results that would allow the results of the test to be accurate and correct. Without the correct temperature and environment the bacteria will give inconclusive results which will alter and skew the end results and may lead to the wrong conclusion. By using the methods that were obtained and learned through the microbiology class allowed the skills and knowledge to determine the bacteria and execute the tests in order to determine the culture. Being able to figure out an unknown culture or bacteria is very important and a great knowledge to have. It helps people every day from finding cures to bacterial infections, discovering new kinds or simply just knowing the limits of what they are capable of. It allows scientist to know how to kill them treat then and ect. along with determining if they are harmful or benefit humans, and plants Along with being able to identify different species ofShow MoreRelatedstaphylococcus aureus868 Words   |  4 PagesThis paper explores the study of an unknown bacterial culture. The bacterium were randomly assigned in a double blinded fashion to alleviate scientific or experimental error in determining their gram stain, morphology, arrangement, and scientific classification. There were eight unknown bacterial cultures given, with the unknown bacterial culture being one of the eight bacterial cultures. A myriad of tests and experiments were performed on the unknown bacteria in order to b e able to properly classifyRead MoreUnknown Microbiology Lab Report Essay1128 Words   |  5 PagesUNKNOW BACTERIA LAB REPORT UNKNOWN 36 Introduction The purpose of this lab was to identify two unknown bacteria from a mixed culture. 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 othersRead MoreIdentifying Salmonella Choleraesuis1410 Words   |  6 Pageswhat an unknown bacteria was using several different microbiology lab techniques including an API test, an oxidase test, a gram stain, a hanging drop slide, and morphology identification. The unknown bacterium, which was contaminated with Serratia marcescens, was isolated by streaking the bacteria solution to single colonies. The isolated unknown white bacteria, had the appearance of circular form, convex elevation, entire margin, elongated cocci. The tests than showed that th e bacteria was gram-negativeRead MoreEssay about Applying the Methyl Red (MR) Test 982 Words   |  4 Pagestest media contains peptone, glucose, and a phosphate buffer (Stout et al, 45). To perform the MR test, I used the stabbing technique to inoculate the MR media. I sterilized the stabbing utensil under an open flame, obtained a small amount of unknown bacteria, and stabbed the MR media. Once the MR media was inoculated, I let it incubate for 24 hours in the 37 °C hot room. After the 24-hour incubation, I added 15 drops of Methyl Red to the MR media to test for mixed acid production. VP test (a.k.aRead MoreEssay on HS320 Microbiology Unit1 Assignment1302 Words   |  6 Pagesconstructed a number of simple microscopes and observed details of numerous forms of protozoa, fungi, and bacteria† (Introduction to Microscopes, n.d.). During the 1700s, microscopes were used to further explore on the microbial world, and by the late 1800s, the light microscope had been developed. â€Å"The electron microscope was developed in the 1940s, thus making the viruses and the smallest bacteria (for example, Rickettsiae and Chlamydia) visible† (Introduction to Microscopes, n.d.). The studies ofRead MoreLab Report : The Gram Stain1706 Words   |  7 Pagesnor did I plagiarize any material. Signed: _____________________________________________ Eric Zuberi â€Æ' I. Introduction In all areas of biology, it is easy to see that structure is related to function. This statement holds true in microbiology as well, the study of microorganisms, including bacteria. One characterizing feature of bacteria is the cell wall, which can generally (although not in all situations) be categorized into one of two categories: either Gram positive or Gram negativeRead MoreDna Rn The Biological Diversity1295 Words   |  6 Pagesof microorganism which includes bacteria, archaea, fungi, and protists. The study of microorganism is important because they play a large role in thce environment. Although microorganism are not well known, which might be due to their small size, and the hardship of recognizing them. Particularly bacteria and other prokaryotic organisms. Only 3100 bacteria are recognized in Bergey’s manual out of 300000 to 1000000 species of prokaryotes that is on earth. Bacteria although mostly thought of has beenRead MoreIdentification Of Unknown Organisms And Two Eukaryotes3349 Words   |  14 PagesIdentification of Unknown Organisms Benjamin Nibarger Professor Hoffman Monday 11:15 AM Group Members - Jamie Jerome, Natalie Perez, Ruth Pinzon September 27, 2014 â€Æ' Introduction The purpose of this study is to identify four unknown organisms. The unknown organisms have been assigned randomly to six-research groups by Professor Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi,Read MoreIntroduction. Bacteria Is Used As Expression Host For Mammalian1685 Words   |  7 PagesIntroduction Bacteria is used as expression host for mammalian proteins due to its rapid and simple system of expressing recombinant proteins as it has a short doubling time. E.coli is a widely used system as there is more than enough knowledge about its ‘genome sequence, physiology and genetics’ (4). E.coli is a ‘gram-negative bacterium’ (5). Bacteria has a simple genetic manipulation with rapid expression which is suitable for large-scale fermentations and makes it easier to handle in a standardRead MoreDna Sequences Using Polymerase Chain Reaction1605 Words   |  7 PagesChain Reaction Edwina Abou Haidar, Houssam Al Koussa, Mary AbedAlAhad. Department of Biology, Lebanese American University, Byblos, Lebanon Abstract The 16s rRNA gene sequencing is a widely common amplicon sequencing method used to identify and compare bacteria in a given sample. This method is well established and allows to study phylogeny and taxonomy of complex microbiomes. In this study, an unknown sample of extracted microbial DNA was analyzed by performing the polymerase chain reaction
