multiple types of testing in order to determine the identity of the unknown organism. The tests performed to identify the unknown organism included Gram Staining‚ Fluid thioglycollate/aero-tolerance test‚ Methyl Red-Vogues Proskauer‚ SIM test‚ Lysine Decarboxylase test‚ Lactose Fermentation test‚ Simmons Citrate test‚ and TSI test. The Gram staining technique showed that the organism was Gram negative and bacilli shaped. The fluid thioglycollate test showed that the organism was a facultative anaerobe

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 foods or 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. Hypothesis By slowly narrowing down the bacteria by each test‚ I will be able to conclude the unknown bacteria by its special characteristics. MATERIALS AND METHODS An

Introduction Gram staining was developed by Christian Gram in the 1800’s‚ a Danish bacteriologist. (Smith and Hussey‚ 2005) It was the first differential staining technique and most common used in microbiology. Furthermore‚ bacteria are transparent and cannot be seen through the microscope. For that reason‚ Gram staining is an important tool for distinguishing between two main types of bacteria Gram-positive and Gram-negative. The Gram stain differentiates the Gram positive and gram-negative on

While microbes are often viewed negatively due to their association with many human illnesses‚ microbes are also responsible for many beneficial processes such as industrial fermentation (e.g. the production of alcohol and dairy products)‚ antibiotic production and as vehicles for cloning in higher organisms such as plants. Scientists have also exploited their knowledge of microbes to produce biotechnologically important enzymes such as Taq polymerase‚ reporter genes for use in other genetic systems

carried out in properly supervised manner to compare the unknown bacteria to the six known that were mentioned above. First it was the Gram staining procedure used to categorize bacteria in two groups‚ gram positive and gram negative. Gram staining is one of the most useful test used in the clinical setting to identify bacterial colonies due to their broad staining spectrum. (Black‚ 2008‚ pp. 70-71) The basis of the Gram stain is that gram positive bacteria retains the color of the primary dye‚ the
