Autumn White Biology 258-05 November 26‚ 2012 Unknown #19 Enterbacteriaceae Enterobacter aerogenes ABSTRACT The objective of this report was to identify an unknown microorganism through several differential media tests. Over the course of a couple weeks‚ ten tests were performed. First‚ a gram stain was performed‚ indicating the bacterium was gram negative. An aerotolerance test determined that the bacterium was a facultative anaerobe. Next‚ a negative result in the

Since the Grignard reagent can easily react with water‚ all glassware including the 25 ml round bottom flask‚ magnetic stir bar‚ 3 and 5 ml conical vial‚ 50 mL Erlenmeyer flask‚ claisen adapter‚ drying tube and 5 glass pasteur pipets were first added to a 250mL beaker and placed in the oven for 30 minutes. After the completion of the thirty minutes‚ 0.150 g of shiny magnesium turnings and a stir bar was first added to the round bottom flask and the claisen adapter along with the drying tube packed

Experiment 21: Salmonella and food contamination Purpose /Objective Objective: To test salmonella in spinach sample over five lab periods. Food contamination of salmonella can cause serious illness. Only small numbers of salmonella need to be found for a food product to be considered contaminated. Tests used Pre-enrichment- lactose broth Selective enrichment broth- with Tetrathionate Brilliant Broth Selective Plating- Brilliant Green Agar Isolation of salmonella conformation- is preformed

Coli bacteria. We began the lab by first obtaining two sterile microcentrifuge tubes‚ one was label “GFP+” while the other one was “GFP–” because this one served as a control meaning nothing goes inside this one. With gloves on 25 microliters competent cells‚ which is e. Coli bacteria compete in calcium chloride and heat shock was added to each of the microcentrifuges. Eventually‚ both of the

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put

The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda
