Streaking

isolated using the streaking technique as the experiment is conducted. The benefits of the streaking technique is when a cultures has multiple species they are able to be more easily identified once they have been isolated. This experiment is much like the experiments completed on an agar plate but on one a much larger scale and where techniques

Lab Three: Streaking and Spreading Plates Introduction In this laboratory experiment, we was introduce to an introduction to streaking and spreading of bacteria in agar plates such that single cells can be isolated from one another, each cell can reproduces to form a visible colony composed of genetically identical clones. Streaking and spreading bacteria is to obtain individual colonies is usually the first step in genetic manipulation of microorganisms. Materials • Petri dishes • Metal transfer

Streaking Method Samantha Walthall Dr. Gerald McShepard BIO 411-01 Summer 2016Abstract When you hear the word “Bacteria” you automatically assume the worst; you would conclude that it means something is contaminated or can be harmful. But in all actuality that is not the case. Bacteria is used in laboratories every single day. It can be used to create medicines and vaccines and can even be found naturally occurring in our food and environment. To change the stigma that comes with bacteria, it

It was around two in the morning and my throat started to close I was streaking in pain. I called my mom because she was at work and I told her to take me to the hospital. She rushed home right away. She ran around the house so fast trying to get everything I needed to go to the hospital that my head started to spin. When we got in the car we was at the hospital in a blink of an eye.When the doctor came in with the bad news my world stopped.He barked I needed surgery to have my tonsils

unknown bacteria. The first procedure was streaking tryptic soy agar plate (TSY). The purpose of streaking is to identify the bacteria in a sample presenting a pure culture of colony morphologies. After several hours of incubating the streaked plate, visual isolated colonies were present. The steps to streaking are as follows; Flaming an inoculation loop with a Bunsen burner until red hot, then allow to cool before taking the unknown bacterial sample. Streaking four quadrants onto the TSY medium plate

1 Streaking allows bacteria colonies to grow well separated from each other. The aim of the procedure is to obtain single isolated pure colonies. 2 Only 1 bacterial cell is needed to start a colony. The cells use binary fission to divide, the microbes' DNA splits to form a new cell and this process repeats until there are billions of cells. 3 The members of the colony are genetically identical because binary fission produces two identical daughter cells. 4 Autotroph: An autotroph or producer

background was really full. He most likely sat near the front, for easier access onto the field rather than climbing through bunches of people, naked. When he got on the field the officials probably had to chase him because I have seen videos of people streaking and they are often not easy to

Introduction Whenever there is an unknown disease caused by microorganisms, tests are usually made in order to identify the organism causing the disease. There are several tests that need to be made and they include tests such as performing a gram stain, streaking a plate to isolate colonies, inoculating a broth culture, inoculating API strip, and performing oxidase and catalase tests. Having knowledge on how to identify these tests are of high importance in the medical field so it would be to the advantage

Were you alive in the 1970’s? If so, you were alive in a crazy time, where everyone's outlooks and way of life changed dramatically. The book The Great Funk by Thomas Hines, shows how the 1970’s were overall more focused on the individual and finding out who you truly were as a person. The 1970’s was a time of immense creativity and experimentation in regards to our consciousness, the human body, and the way of life in the home. These changes came after, and were caused by many failed aspirations

INTRODUCTION Bacteria has always been one of the most important organisms in the field of molecular genetics, according to scientists. More specifically, Escherichia coli remains one the most famous types of bacteria due to the general harm it causes on hosts. E.coli lives in the intestines of humans and animals, and even though it does not trigger any problems most of the time, certain strains can cause food poisoning. What makes those types of bacteria even more interesting from a research point
