Identify and Investigate an Unknown Microorganism

The purpose of this experiment was to identify two species of bacteria from an unknown mixed sample out of a possible twelve strains. With the intentions to correctly identify the unknown bacterium, a plethora of test were executed and documented, yielding the appropriate results for that particular sample. In this experiment, many methods were critical in the identification of the unknown. A dichotomous key, streaking and staining techniques, microscopy, differential and selective media, colony

I. Identify Preliminary Issues This multistate outbreak of Salmonella Tennessee case was published by the Centers for Disease Control (CDC) in March of 2007 to inform the public of the outbreak that was discovered and in order to prevent other people from getting sick. The Salmonella infection was associated with the consumption of Peanut Butter, specifically with Peter Pan peanut butter and Great Value peanut butter brands manufactured by ConAgra. Since both brands were manufactured in the same

Mold Introduction The Pew Center on Global Climate Change reported in September 2011 that the number of flood damages in the Northeast continue to rise. In Wilkes-Barre, PA, 75,000 people were evacuated as the Susquehanna River crested at a record of 42.7 feet. An estimated 5,400 homes and business suffered some sort of flood damage during that event, and 124 sewage treatment plants were affected by the flood, with 14 of them spilling raw sewage into waterways. Reports indicate that mold infestation

consumption? In twenty years, the Earth’s population will need fifty-five percent more food than it is currently producing with the same or fewer resources. This issue could be resolved, but the full effects are still unknown. Genetically modified organisms are plants, animals, or microorganisms that have had their genetic material changed in a way that does not happen naturally. According to the United States’ National Library of Medicine, genetically engineering organisms has been around since the 1990’s

DNA Mutations Over a lifetime our DNA can undergo changes or ‘mutations’ in the sequence of bases; A, C, G and T. A mutation is a change that occurs in your DNA sequence, either due to mistakes when the DNA is being copied or as the result of environmental factors.Mutations are essential for evolution to occur because they increase genetic variation. Mutations can occur during DNA replication if errors are made and not corrected in time. The mutation can have a positive or negative affect on humans

that Affect the Activity of Urease Aim: To investigate closely the factors that can affect the activity of urease. The effect of concentration and temperature can be studied over a period of time leading to the order and activation enthalpy of the reaction. Introduction: UREASE (NH 2 ) 2 CO + 3H 2 O ----------> 2NH 3 (aq) + CO 2 (g) Urease is an enzyme found in microorganisms, invertebrates, and higher plants. It catalyses the
