Student: Yi-Ren Wang Course: BIO-205 BD2 Microbiology Instructor: Dirk VandePol Date: 6/21/2013 Streak Plate Isolation for Obtaining Pure Culture 1. When an agar plate is inoculated‚ why is the loop sterilized after the initial inoculation in put on? Ans: We use agar plate to inoculate microbes by zipping the loop on the agar several times. We streak on the agar plate four time‚ propose is to isolate the unknown bacteria. Therefore‚ the first time to streak on the plate‚ there are

A pathogen is a tiny non-visible disease causing microorganism such as Bacteria‚ Virus and Fungus. Both the scientific name and common name for Actinomycosis is Actinomycosis. The pathogens that cause Actinomycosis are from a species of Actinomyces‚ most commonly known as Actinomyces Israelii and Actinomyces Gerencseriae. The species of Actinomyces are an Actinobacteria class of Bacteria. The pathogens are endogenous‚ meaning the bacteria originate from inside the body‚ making them not liable to

how it can be treated‚ to knowing the correct microorganism to be used for producing certain foods or antibiotics‚ to biological warfare. Their uses are infinite as are their abilities to develop and adjust to altering environments. That is why it is so significant to be competent to identify microorganisms. This study was conducted by applying techniques and experiments cultured in microbiology lab for the identification of the unknown microorganism. Introduction: Identification of bacteria is significant

answer this question‚ we were required to complete three bacterial labs that helped us to understand what microorganisms are and how to identify and classify them. Thus‚ the main purpose of this project is to identify our unknown microorganisms‚ more specifically‚ our unknown bacteria. There are many ways to distinguish and classify bacteria. You can distinguish bacteria from other microorganisms by its size. Bacteria are around one micrometer and yeast is 4-40 micrometer

of infection that might be caused by the microorganisms being studied. This laboratory does not require the use of virulent human pathogens. However‚ many types of microorganisms are potentially pathogenic. This means that‚ although they would not cause disease in a normal healthy host‚ they might possibly do so if a large enough quantity of the microbes came into contact with a compromised host‚ such as by wounds and cuts. In addition to microorganisms‚ there are some chemicals used in this laboratory

Through processes know as wet mounts and simple stains‚ observing living microorganisms through a compound microscope can generate a clearer understanding of their appearances and movements. Microorganisms are living things that for the most part cannot be seen through the naked eye. They live on and among humans‚ as well as plants‚ animals‚ and all that is a part of the Earth. Harmless as most seem to be to humans‚ microorganisms are an important relevance of study for human interest in varied perplexities
