There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics to other purposes such as knowing the exact microorganism has to be used to make certain foods. This experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by the lab instructor. The methods that

Chemistry Lab Report Purpose The purpose of this lab is to determine the identity of an unknown liquid by measuring its density and its boiling point and try to match it with those solutions given in Table 2 of experiment 2. Procedure Part A In Part A‚ The main purpose was to find the determination of the density of the unknown (j41) and by doing that we had to determine volumes of the unknown liquid (j41) using three different volumetric devices which are graduated cylinder‚ pipette

aureus)‚ the serum will coagulate‚ resulting in a clot (sometimes the clot is so pronounced that the liquid will completely solidify). * If negative‚ the plasma remains liquid. The negative result may be S. epidermidis but only a more detailed identification test can confirm this‚ using biochemical tests as in API tests and BBL CRYSTAL methods.

Identification of a Conjugated Diene from Eucalyptus Oil Purpose: The purpose of this experiment was to prepare the Diels-Alder adduct of the unknown Conjugated diene in eucalyptus oil‚ to separate the adduct‚ and identify the unknown diene from the melting point of it¡¯s adduct. Introduction: This experiment was performed using techniques of heating under reflux‚ vacuum filtration‚ recrystallization‚ and melting point measurements. These techniques were used to separate the Diels-Alder

Phelps‚ Biology 205 MW 2:10pm. Unknown Organism Paper The unknown organism tested in the Mesa lab was collected from in between the toes of my puppy‚ Riley. The original culture grown consisted of dozens of visibly different organisms of varying colony colors and growth patterns. I chose to test a smaller‚ red colony for my experiments. Based on its gram reaction and oxygen requirements‚ the following tests were performed to reach my presumptive ID: Test Performed Result Gram Stain +

Identification of Victims Identifications of victims is an issue service providers and law enforcement struggle with daily. Trafficking is very much a hidden crime‚ meaning most individuals could not identify a trafficking victim‚ even if they lived in their own community. There is only very recently increased awareness of trafficking‚ its victims‚ how to identify them‚ and how to treat them. According to Heather Clawson and Nicole Dutch‚ trafficking victims are kept isolated with no freedom and

When introduced to Starch Unknown #7 produced no zone of clearing showing that it did not contain the enzyme amylase. When introduced to the Lipid Unknown #7 did produce a zone of clearing indicating that it did contain the enzyme lipase. When introduced to Casein Unknown #7 produced no zone of clearing indicating that it did not contain the enzyme protease. When streaked onto the Gelatin‚
