Incubated both specimens for 48 hours observed and recording results of growth at 24 and 48 hours. After observing final growth pattern at 48 hours prepared both wet mount and direct stain slide for each of the cultures. Viewed under microscope using both the 40X and 100X oil immersion lens.

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

Virtual Reality: How it Affects Our Lives. INF. 103 September 5‚ 2009 We can find many uses for virtual reality in our lives‚ and we also find it in many instances that some would not even think of. We can use virtual reality for education‚ job training‚ social networking‚ and even gaming. In this paper I will give examples of each as well as how virtual reality was created‚ and how long it has actually been around. I will also tell how virtual reality can be detrimental to it users.

Many types of projects are possible when you are able to count bacteria. For example‚ you could count the bacteria in drinking water‚ fresh milk‚ old milk that is slightly sour‚ buttermilk‚ yogurt‚ mud puddle‚ lemonade‚ and many other things. Or you may want to know how fast Chlorox kills bacteria. If you add some Chlorox to a culture and count the surviving bacteria at suitable intervals you can plot killing the killing curve and determine whether the killing is single hit or higher order. It will

Flesh-eating bacteria strikes in Florida On June 16th‚ 26 year-old Cason Yeager went for a swim in Florida in Hernando County and later died from contracting the flesh-eating bacteria‚ Vibrio Vulnificus. This bacteria can be found worldwide‚ most particularly in the warm coastal regions but there have been reports in other parts of the world in non-warm waters. According to the CDC in 2013‚ the case count of the vibrio vulnificus was 104 in thirteen states with six hospitalizations. No deaths‚ but

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 produce plasmid-encoded proteins

Bacteria‚ such as Vibrio natriegens‚ are single cellular‚ microscopic microorganisms. Bacteria grow by cell division‚ mainly by a process called binary fission‚ where two cells arise from one single cell (Madigan et al.‚ 2015). In bacteria such as Vibrio natriegens‚ who are curved-rod shaped microorganisms‚ they elongate to almost twice their own size and form a dividing wall in which splits the single cell into two daughter cells (Madigan et al.‚ 2015). There are four phases to bacterial cell growth:

discovered by German Bacteriologist Theodore von Escherich in 1885(quote). It is commonly known as E. coli and 0157:H7; E. coli found in the human intestinal tract and is found in multiple forms. E. coli is rod shaped and the size of two microns to one micron. Widely known for the deadly stain found in feces and meat. The pathogen is still a major instrumental issue in human health and is easily infectious with contaminated sustenance. E. coli is gram-negative bacilli tested in clinical settings from stool
