identifying these pathogens and their related epidemiology has become increasingly more important. The purpose of this study was to identify an unknown bacterium in a controlled laboratory environment over a 5 week period. Utilizing a variety of differential testing and staining methods learned in the microbiology course‚ students were to determine the identity of an assigned unknown organism. Observations were made and recorded each week to narrow down the scope of identification. Data has been

Purpose: To identify an unknown bacterial specimen using basic laboratory technique and biochemical tests. The unknown bacteria will be one of the following: Enterococcus faecalis‚ Staphylococcus saprophyticus‚ Escherichia coli‚ Enterobacter aerogenes‚ Proteus vulgaris‚ Salmonella [I assume typhimurium]‚ or Shigella [either flexneri or sonnei‚ we used both in our lab during the semester]. Procedure {and observations}: Observe bacterial colony morphology. {Colonies are large‚ beige or

Environmental Impacts used to enhance a more common food crop‚ such as corn‚ it might introduce a similar allergen which could have a severe health impact to the consumer. An alteration to a certain plant might make it inedible or harmful to another organism such as an insect that relies on it for food. It can harm organisms that are desirable or can upset the balance of the food Organisms that have been

The identification of the unknown culture was accomplished by identifying the bacteria based on its specific metabolic characteristics and morphology. It is suggested that culture 11 is a sample of Enterobacter aerogenes. Introduction: This experiment was centered on metabolic and biochemical testing

report required the successful identification of two unknown substances through experimental testing on a selective collection of materials and equipment. For the first substance (which will be either tin or aluminium)‚ two tests shall be done to ensure a decisive and educated decision onto what the substance is. The first step utilizes the dramatic difference in density between the two substances by measuring the volume and mass of the unknown substance. By calculating the volume (through displacement

GMO’s are Genetically Modified Organisms. Many people argue that GMO’s are a problem and hurt the ecosystem‚ economy‚ and health of society. GMO’s are important because they help the food industry thrive‚ protect the crop to help it grow‚ and make the crop more efficient. First‚ GMO’s are important because they help the food industry thrive. This is because many GMO’s are manufactured and sold as a convenience to people‚ thus prompting them to buy the product. GMO’s greatly impact the food industry

Genetically modifying organisms works just like an advanced form of cut and paste. During genetic modification‚ DNA is taken from and unrelated plant‚ animal or bacteria and inserted into a different organism to get it to produce the desired traits. The DNA is“cut” from one organism and “pasted” into and unrelated

the nineteenth century‚ the time in which Romanticism had a significant influence upon literature. The literary genre of romanticism has six main components: the individual‚ imagination‚ personal and social intuition‚ nature‚ emotion‚ and the unknown. The unknown is typically portrayed as death as throughout the time period in which Romanticism was prominent as death was a mystery. While humans can understand the events that occur whilst they live‚ they know nothing of what happens during death or after

Purpose: To find how pH and temperature levels affect the enzyme Background: Enzymes are a type of protein vital to sustaining life‚ it works with vitamins and minerals as a biological catalyst‚ which lowers the activation energy for a reaction to occur. Each individual type of enzyme does a specific job‚ and they do not die‚ they are reused. For example‚ catalase is an enzyme found in almost all living cells that will break down hydrogen peroxide and turn it into water and oxygen. The

in the War In the poem‚ “The Unknown Citizen‚” a short eulogy is presented at a funeral for an unidentified soldier. When providing details about the citizens life‚ the speaker instead uses impersonal facts and government based statistics‚ rather than intimate components about who the soldier was personally. The author also displays the tone of the poem as lighthearted‚ making the speaker seem untroubled about the death of the soldier. In W.H Auden’s poem‚ “The Unknown Citizen‚” the author uses his
