Aim To measure how different concentrations of mythelin blue affects the rate of diffusion through agar jelly. Hypothesis The diffusion of mythelin blue is directly proportional to its concentration‚ hence as the concentration increases; the rate of diffusion increases too. Controlled Variables Time time was kept constant while testing the diffusion spread of mythelin blue with each concentration. Temperature the experiment was undertaken in room temperature as change in temperature can

Agar From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search Not to be confused with auger or augur. For other uses‚ see Agar (disambiguation). Culinary usage Mizuyōkan - a popular Japanese red bean jelly made from agar. Scientific usage A blood agar plate used to culture bacteria and diagnose infection. Agar or agar-agar is a gelatinous substance derived by boiling[1] a polysaccharide in red algae‚ where it accumulates in the cell walls of agarophyte and serves as the primary structural

Petroleum jelly‚ petrolatum‚ white petrolatum or soft paraffin‚[1] CAS number 8009-03-8‚ is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25)‚[2] originally promoted as a topical ointment for its healing properties. Its folkloric medicinal value as a "cure-all" has since been limited by better scientific understanding of appropriate and inappropriate uses (see uses below). However‚ it is recognized by the U.S. Food and Drug Administration (FDA) as an approved over-the-counter

Margarita SA: VOL RATIO AND AGAR BLOCKS Conclusion: For this experiment the agar jelly had to be cut in to five different block sizes‚ after that has been done we had to add all five blocks in to the test tube with the acid and time to see how long it would take for the colour to change from a pinky purple to clear. From this experiment I learnt that the bigger the size of the jelly is the more time its going to take for the colour change to take place

The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases - enzymes which break down agarose into oligosaccharides. This physiological class branches through genii‚ regardless of Gram Stain status or morphology. Through a review of scientific literature we can find identification methods‚ optimum conditions and the

growth of bacteria on Agar plates Hypothesis: That the bacteria will grow in colonies throughout the agar plates except for the one with the anti-biotic loop because some will fight off the bacteria. Method: (Method taken from prac sheet) Plate 1: Use the swab to cover your entire agar plate in your bacteria. You only need one swab of bacteria but be careful to cover the entire surface of your agar in a layer of bacteria. Carefully place an Antibiotic Mastring on top of the agar (use tweezers) in the

Making Agar Cushions 1. Start with wearing gloves and swabbing them with 70% ethanol to keep the materials that will be used in the experiment sterile. 2. Wipe the work station with Wescodyne and paper towels. It is important to keep the sterile materials such as slides in petri dish‚ Pasteur pipette in container and forceps covered as much as possible. 3. Place four to five filter papers in the petri dish and drip few drops of water on the strips‚ this will maintain moisture in the agar cushions

Materials and Methods: Inoculation of the unknown was done on a nutrient slant agar The nutrient agar was then incubated at 27°C for one week. The agar appearance was observed and recorded. There was growth that appeared pinkish in color. The first test we did was basic stain using a heat fixed emulsion which kills the bacteria and allows them to adhere to the slide and thickens their protein for better staining. I then covered the heat fixed emulsion with crystal violet for one minute. The stain

Agar and Media Preparation— Agar plates containing King’s B Agar were often used throughout the experiment to support growth of Pseduomonas fluorescens. A recipe was used that included a mixture of 10g Proteose Peptone #3‚ 1.5g Potassium Phosphate Dibasic (K2HPO4)‚ 30ml 50% Glycerol‚ ~965ml water and 20g agar. The mixture‚ post- autoclave‚ was left to cool and 5ml 1M Magnesium Sulfate (MgSO4) was added and created about 40 plates. King’s B Medium was made using the same procedure as the King’s B
