- Methyl red test does the color of the medium change to red when methyl red was added? Is it positive or negative for mixed acid fermentation?Match the chemical reaction to the visual effect of the product/biochemical test description 1. This assay's color change relies on an initial reduction reaction resulting in a black precipitate if the organisms is "positive" 2. The visual production of gas from this reaction indicates this organism can break down toxic byproducts of aerobic respiration. 3. This assay relies on a pH indicator (phenol red) for a color change. An organism that was "positive" for the certain enzyme in this assay, would result in a pink color change. 4. If an organism was incubated in simple broth containing a phenol red pH indicator and a sugar source, and the broth turned yellow following bacterial growth, that would be evidence of this reaction occurring. 5. The reaction representing this assay, works by producing a red colored product upon addition of a reagent, which tells us the organism possesses the enzyme required to break down a particular amino acid.What is the oxidation fermentation test? Please explain the testing and its results and the chemistry behind it? Please explain for a beginners level. Thank you
- Zinc Floatation 1. What parasite may be recovered out of this procedure? 2. What are the advantages and disadvantages of this technique? 3. Why should zinc sulfate be used with specific gravity of 1.18?Procedure 1 to 2% of agarose gel was prepared in the running buffer. Mixture was swirled and mixed. The agarose and buffer mixture were boiled and mixed well until the agarose was completely dissolved. The agarose was cooled on the benchtop or by incubation in a 65 °C water bath. The gel tray was placed into the casting apparatus. The appropriate comb was placed to create the wells. The molten agarose was poured into the gel mold. The agarose was allowed to set at room temperature. The comb was removed and the gel was placed in the gel box. The running buffer was added until it covered the surface of the gel. A loading dye was loaded and the serum protein samples to be separated carefully. The lid was replaced to the gel box. Ensure the leads were plugged into the correct slots in the power supply. The power was turned on and started the electrophoresis running until the dye was migrated to an appropriate distance. After electrophoresis, the gel was stained with Coomassie brilliant…Procedure 1 to 2% of agarose gel was prepared in the running buffer. Mixture was swirled and mixed.
