Microbiology-2460 Lab-003 March 31‚2008 Lab Report-Escherichia coli Abstract The purpose for this lab report was to identify and inform of an unknown bacteria that has been causing a patient to have lower abdominal and pelvic pain. To obtain the identification of this unknown bacterium‚ several biochemical tests needed to be performed in order to prescribe the correct medication to treat and cure the symptoms. Introduction In a lab today‚ I am to identify an unknown bacterium that is

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Sodium: Sodium is essential to all living beings Basic functions: Sodium has 3 main functions: it helps in the absorption of glucose and some amino acids in the small intestine‚ it is required for normal muscle and nerve function‚ and it aids in water balance. Glucose generated by digestion of starch or lactose is absorbed in the small intestine only by cotransport with sodium‚ a fact that has exceptionally important implications in medicine. Glucose and galactose are taken into the enterocyte by

This is then reduced by means of iron powder or sodium sulphide to get para-aminophenol. The recovery of para-aminophenol is completed by dissolving the para-aminonphenol hydrochloride salt in water‚ decolourising the aqua solution and crystallising the para-aminophenol by neutralizing the salt. The resulting para-aminophenol is reacted with acetic anhydride to produce paracetamol. The reactions are summarized as shown below: Process using Paranitrochlorobenzene as a starting raw material

of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel‚ which leaves a clean test tube. Incomplete combustion is the reaction of an

I) Introduction In this lab‚ a test was conducted to determine how the relative redox activity of chloroplasts from spinach leaves‚ which were performing photosynthesis‚ would change when in the presence or absence of light. To observe these changes in redox activity‚ the chloroplasts were exposed to DCPIP‚ a chemical that changes color according to such activity. By determining the redox activity of the chloroplasts‚ it could then be inferred which chloroplasts were photosynthesizing more actively
