Lab 1-3: Aseptic technique

If the bacterial cells are grown in the presence of the antibiotic ampicillin then only the cells that took up the plasmid have the resistance gene. As a result the resistance gene will have to keep the plasmid and the GFP gene. People on gluten free diet or those with severe allergies should be careful because xanthan gum is produced by bacterial fermentation of a sugar-containing medium which is often a potentially allergenic substance such as soy, corn, wheat or dairy and an allergic response may be triggered in people exceedingly sensitive to the growth medium.

Although, the vast majority of industrially manufactured xanthan gum contains far less than 20 ppm gluten, which is the limit for "gluten free" labelling in Canada, United States and Europe. Since information about producing practice is not available, you can check with the manufacturer to find out more info on how it is produced or you. Ultimately, oxygen is produced, than released, along with carbohydrates used for food. Photosynthesis is, in a nutshell, a chemical process through which plants, some bacteria and algae, produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy.

In this experiment, we saw that even underwater plants Elodea respire, by exchanging carbon dioxide with the water, in the form of Carbonic Acid. When CO2 is used in photosynthesis, the level of Carbonic Acid drops. Thus, water living organisms have the ability to change the pH of their environment as they add or remove CO2. Explain the relationship between the ionisation of amino acids and pH Structural diagram of the neutral structure Structural diagram of positively charged structure Structural diagram of negatively charged structure Explain how the form of an amino acid, whether positively charged, negatively charged or neutral, depends of the pH of the solution?

To test if it is now a negative ion a process called electrophoresis. If the amino acid has dried and then heated gently it would appear as. Mannitol high salt testing is done in order to determine if the bacteria is salt tolerant and can ferment mannitol. Catalase activity test establishes whether the bacterium produces the enzyme catalase. The eosin methylene blue test or EMB, inhibits the growth of gram positive bacteria and tests whether or not gram negative bacteria can ferment lactose. Lactose fermentation testing is done to see if the bacterium is capable of fermenting sugar by testing for acid and gas production. These are the possible tests that are needed in order to identify unknown. Proteins are considered negative buffers and pair well with hydrogen.

An intracellular blood buffer like hemoglobin is used because it binds well with hydrogen ions and carbon dioxide. The phosphate buffer system is important because it regulates the pH in the cytosol. Dibasic phosphate and ammonia are considered renal buffers. This test was to check for the presence of the catalyst catalase which liberates molecular oxygen. This catalyst is necessary for an aerobic organism to survive in aerobic conditions. After the experiment it was observed that my Gram positive organism did in fact bubble and utilize catalase. The third test conducted was on the MSA agar. This test was conducted for the purpose of selective and differential whether or not my organism can tolerate high salt concentrations.

Citrate test is used to identify if an organism is capable of utilizing citrate as a sole carbon source. Citrate medium contains sodium citrate as the only carbon source. The test will conclude and the agar will turn blue it means citrate was. The bacterial species concept is the identification and naming of microbes based on relating physical and physiological features of the unknown to the fitting taxa. This concept created a guide on naming all Bacteria and Archaea. The biological species concept on the other hand, does not take physical appearance into account on comparing and contrasting organisms but defines a species as part of populations that potentially interbreeds in nature.

Students cannot classify microbes within the guidelines of a. The six bacteria used in this lab were, Citrobacter freundii, Bacillus subtillis, Enterobacter aerogenes, Staphylococcus epidermis, Enterococcus durans, and Escherichia coli. Citrobacter freundii is a Gram-negative rod shape bacteria. The MSA plate will grow Citrobacter freundii, Bacillus subtillis, Enterobacter aerogenes and will have a yellow color change while Staphylococcus epidermis will not grow nor have a color change to yellow. The MacConkey agar will have growth with Escherichia coli, Enterococcus durans, but not Staphylococcus epidermis and Bacillus subtilis since it is a Gram-positive.

Only Escherichia coli and Enterococcus durans will be the species fermenting. PEA agar isolates Gram-positive species from Gram-negative bacteria. When reduced the agent was clear but when oxidized it turned deep purple to a blackish color. This agent Cytochrome C Oxidase was the electron donor. This test did not distinguish whether the organism is oxidative or if it fermented. In the Oxidative fermentation tube the media was a differential media that helps determine whether specific bacteria can oxidize or ferment to metabolize glucose. Citrate test checks to see which bacteria could citrate as the only source of carbon. In the Oxidative fermentation tube the media was a differential media that helps determine whether specific bacteria can oxidize or ferment to metabolize glucose.

Citrate test checks to see which bacteria could citrate as the only source of carbon. A positive test shows that an alkaline environment ia created and that the pH level rose. The color of the media changed from green to blue if its positive. The Bile Esculin agar test has its medium as selective and differential. After a gram stain was done unknown was identified as a gram positive organism because when observed under the microscope the organism appeared purple with cocci in clusters. The organism was also catalase positive which means that it produced enzyme catalase and bubbled when hydrogen peroxide was added to it.

Three test were conducted based on the result of the gram staining procedure. The Blood agar is a bright red, opaque plate and the streaking or the inoculation technique was a modified streaking for isolation with a heavy quadrant one. Compare the result to the chart on the back of the urinary pH test strips bottle, and record data. Clean the stirring rod with water before moving on to the next test tube.

Repeat this process for each increment 2 mL, 3mL, 4mL Figure 1: Picture of bean solution mixed Figure 2: Picture of materials needed for the with alpha galactosidase experiment Safety considerations: Be careful with the beakers, glass stirring rod, and test tubes, as they could break easily and can cause cuts in the skin. A line of best fit will be used to show the relationship between the glucose concentration and the amount of alpha galactosidase. Screening to separate the large contaminants from the water b. Coagulation to attract small contaminants c. Sedimentation where water sits and finishes coagulation d. Filtration to remove any small remaining contaminants and particles e. Disinfection by disinfecting chemicals such as chlorine to kill microorganism or remaining bacteria 2.

Explain the differences between primary, secondary, and tertiary sewage treatment. Proton pump inhibitors PPIs are a group of medicines, such as lansoprazole and omeprazole, that work on the cells that line the stomach, reducing the production of acid. The stomach normally produces acid to help with the digestion of food and to kill germs bacteria. This acid is corrosive so the body produces a natural mucous barrier which protects the lining of the stomach from being eroded.

In some people this barrier may break down and allow the acid to damage the stomach, causing an ulcer. In others, a problem may occur with the muscular band at the top of the stomach the sphincter that keeps the stomach tightly closed. Hence, a calcium chloride and cotton were filled inside a drying tube. The condenser was wrapped with parafilm and a paper towel to avoid moistures from entering. The reagent will act as nucleophilic addition to acetone and work up with hydrochloride acid to synthesize 2-methylhexanol.

Throughout this process, the solution turns dark grey and develop white precipitates. This step indicate that Grignard reagent was generated, and the extra white precipitates were magnesium. Since the solvent is nonpolar, we would expect carotene to have the lowest Rf, then xanthophylls, and chlorophylls would have the highest. As discussed before, this is because chlorophylls are the most polar of the three and carotenes are the least polar of the three.

Based on my results, I would say that the packing and running of the column was effective in separating the pigments as there were quite different Rf values for the original than for the other two colors and the band for the yellow was nothing like the bands for the green. There were no limitations in procedure which negatively affected the end results, so there is nothing I would change to it going.

This transformation usually occurs within plasmids, which are closed circular molecules made up of double stranded DNA. The function of the plasmid is to provide bacteria with genetic advantages such as antibiotic resistance. In this lab, the plasmids provided the ampicillin resistance and the fluorescence. If the bacterial cells are grown in the presence of the antibiotic ampicillin then only the cells that took up the plasmid have the resistance gene.

As a result the resistance gene will have to keep the plasmid and the GFP gene. The vacuum we made was to remove the air from the discs and fill it with the sodium bicarbonate solution. Because they now lack the gases that were keeping them afloat, the discs sink to the bottom of the solution. But when light is added shortly afterward, the discs start to float again. Chlorophyll inside the discs absorb the light and make ATP. Despite this reaction, cellular respiration is still occurring within the spinach leaves. The alcohol also decolorizes the exposed peptidoglycan layer by dissolving away the previously applied crystal violet. A counterstain safranin or fuchsine is then added which recolorizes the bacteria red or pink.

Then, the example for bacillus could be mixed bacillus-Gram stained. For the spiral can be. Nitrate reduction in the gram negative bacteria was conducted and when bacterium produce nitrate reductase when grown in a medium containing nitrate, the enzymes will convert the nitrate to nitrite. If nitrite is present the medium will turn red.

Staphyloccus oxidase transfers electrons from the electron transport chain Lab Report: Citrobacter Aerogenes oxygen the final electron acceptor and reduces it to water. Endospore unit 4 p1 is the fourth staining method used to add contrast. Peptidoglycan plays a Lab Report: Citrobacter Aerogenes role Washtenaw Reflection the Lab Report: Citrobacter Aerogenes wall. After incubation, these tubes Staphyloccus first Staphyloccus for the presence of gas in the Durham tube.
