Abstract: It is important to be able to identify pathogenic bacteria that may be causing harm. Tomato crops can be affected by several different pathogenic bacteria. By using Koch’s postulates‚ it was determined that Pseudomonas syringae was the bacteria causing rot. There are four criteria that must be met when using Koch’s postulates. They are that the organism must be fund in all infected‚ the organism must be isolated in pure culture then once reinnoculated in a healthy host‚ must cause the

Having the ability to collect and identify unknown microorganisms is vital in health and medicine. This capability is important for a variety of reasons‚ such as knowing the causative agent of disease‚ knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study

There were several qualitative tests that could be conducted to determine the identity of the unknown species‚ for example‚ Gram staining‚ Fermentation‚ Catalase‚ Oxidase‚ Starch Hydrolysis‚ Litmus Milk‚ MOI medium‚ and the Gelatin Test. All tests and techniques used were performed in accordance with The Microbiology Lab Manual. Materials and Method: A stock broth culture of

UNKNOW 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 others

MICROBIOLOGY 3444-007 Gram Negative Unknown Unknown Bacteria #14 LeNaiya Kydd 4/2/2014 Abstract In order to be able to identify the unknown organism that was given to us‚ we had to conduct a number of different tests. These biological tests are used because they help us be able to identify the properties of the unknown we have and be able to compare our observed results with actual results of all the potential organisms. When all of the data of the test are put together it is easy to
