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

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

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
