The unknown bacteria A and bacteria B have to be identified by its genus and species. First both bacteria had to be inoculated into a TSA agar media using the streak plate method. Four quadrants were drawn‚ so that the bacteria could be isolated as much as possible. Each bacteria was inoculated into two different plates‚ so that one could be incubated at 37 degrees Celsius and the other at 25 degrees Celsius. Bacteria B‚ which was incubated at room temperature showed red colonies throughout its media

Effectiveness on Gram Positive and Gram Negative Bacteria. INTRODUCTION: Bacteria are microbial organisms which are present in various environments. Many bacteria are good and help humans synthesize materials and assist in biological processes‚ such as digestion. However‚ some bacteria can cause harmful diseases. When harmful bacteria infects the body‚ people take antibiotics in order to suppress bacteria. Different antibiotics have different ways they suppress bacteria‚ and the efficacy of antibiotics depends

How do bacteria affect human lives? Bacteria interact and are a constant in our day to day lives‚ perhaps more than suspected. Bacteria are often thought of as bad‚ however this is untrue‚ there is also many types of ‘good’ bacteria. ‘Good’ bacteria can benefit us by simply helping our digestive system work and helping us in the process of fermentation. Bacteria are extremely helpful in the production of many things such as fuel and medicine. But bacteria directly affect our production of

from a Mixed Culture Mylah Ferland‚ Rivier University MICRO 206‚ March 16th‚ 2016 Introduction: An unknown bacterium experiment‚ this experiment was done to discover what bacterium was in a mixed culture sample. This experiment worked with enteric bacteria which are members of the Enterobacteriaceae and live in the intestinal tract (Willey et al.‚ 2014). Also found in Willey et al (2014) is some characteristics of enterics such as they all degrade sugars by means of the Embden-Meyerhof pathway‚ they

Virus vs. Bacteria Similarities – Virus vs. Harmful Bacteria Virus and Bacteria are similar. But yet they are different. Viruses and bacteria can make copies of themselves once they are inside a living organism (“J. L.”). They are both harmful bacteria and viruses. These bacteria and viruses can be helpful to the body. All diseases that people get are from virus and bacteria( Microbe Magic). Bacteria and virus are both microscopic organisms that have the same brain structure that why they are called

Explaining Bacteria Alexandra Solorzano 1E “ Hey Alex. Could you help your cousin with his homework?” “Okay‚ but I don’t understand what could be hard about fifth grade homework. Anyways‚ what are you learning about George?” “Well today my teacher started to talk about these things called Blackmeria? Or what is backferium?” “Umm I think you mean bacteria?” “Yeah! That’s it!” “Then I guess it’s your lucky day because right now in STT I’m in Cell Biology and we started to look into Bacteria too. Tell

LAB 5: Coliform bacteria in surface waters I. Introduction Many organisms‚ including humans‚ have symbiotic bacteria in their guts that aid digestion. Symbiosis is an intimate relationship between different organisms in which both the host organism‚ e.g. the human‚ and the symbiote‚ e.g. bacteria‚ benefit from each other. In this case‚ the bacterium gets a favorable environment and food source in the intestines of a human. In return‚ these bacteria improve the digestibility of food through

Jennifer Hauss March 4‚ 2015 Bacterial Transformation Lab Report Introduction In this lab‚ the goal was to transform the bacteria e-coli to glow in the dark (or under a black light). Four plates were set up with agar in them for the bacteria to feed on and grow. Changes were then made to the bacteria. One plate was the control plate‚ having only the LB or agar for the bacteria and negative pGLO‚ which is the liquid not containing the plasmid. This is the plate that was compared with the three others

The Identification of Two Unknown Species of Bacteria in Tube #72 Introduction: There are many reasons for knowing the identity of microorganisms. The reasons range from knowing the causative 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

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
