For the juice samples in exercise 3-4, you will be using the pour plate technique. In this exercise, you will add juice to a petri dish and pour agar over the sample and mix. Why is the media (potato dextrose agar, PDA) kept in a water bath until you are ready to use it, and why must you work fairly quickly? (One response answers both questions). The media is already solid and will form chunks O The media has a dye added to it that must be kept at 45°C until ready to use O PDA is a media that allows growth of many types of fungi, and the heat from the water bath keeps the fungal spores from growing. The media is kept liquid in the water bath with heat, removing the tube from the heat source will cause the PDA to solidify

What is your overall dilution factor if you complete 3 serial dilutions using a 100-fold dilution each time? (Show your work)
Order: Zosyn 0.02 gm/kg Supply: 5 gm powder vial with directions to add 10 mL of sterile water as dilutant to create the concentration of 460 mg/mL. Pt weighs 183 lbs. How much dilutant will you use to reconstitute Zosyn?
Five grams of soil were added to 45 ml of sterile water and shaken vigorously. After that, 0.1 ml of this was added to 9.9 ml of sterile water. This was further diluted by 4 successive 1/10 dilutions. The last dilution was used to prepare a spread plate (0.1 ml) . After incubation, 58 colonies were present on this plate. What is the CFU/g of the soil sample? •Assume: 1 g = 1 mL
Why are we using this materials and centrifuging at 15000 rpm? Lipid peroxidation experiment:Materials;• 10% TCA solution• 0.67% TBA solution• Tissue sample Procedures:The tissue sample is buffered at the ratio of 1 x 4 and crushed with the help of a blender. It is centrifuged at 15 000 rpm. Then, 2.5 mL of 10% TCA is added onto 0.5 mL of tissue sample and the tubes are mixed in vortex. It is kept in boiling water for 15 minutes and immediately cooled. After centrifugation at 5000 rpm for 15 minutes, 2 mL of each supernatant is transferred to another tube. 1 mL of 0.67% TBA is added on it and mixed in vortex. After the samples are kept in boiling water for 15 minutes and cooled immediately, their absorbance at 532 nm is recorded. The amount of MDA is calculated by utilizing the highest absorbance specific absorbance values (E = 1.56 x 105cm-1M-1 ) of the MDA-TBA complex formed at 532 nm.

EXPERIMENT 2 Title: Aseptic technique Objectives: To apply the aseptic technique To observe the growth found on the petri dish. Material/apparatus: Gloves, incubator, soap for handwashing, tissues, nutrient agar, 70% alcohol Procedure: Wipe off the bench with 70% alcohol. Draw a line down the middle of the petri dish to divide the plate in half. Label each halves with A and B. Press your unwashed thumb onto the agar at column A. Apply proper handwashing technique. Put the same thumb after washing onto agar at the column B. Incubate the petri dish at 37°C for 24 hours or overnight. Observe and note down the colonies. Results:
Discuss SSD (non-isocentric) technique and SAD (isocentric) technique including the advantages and disadvantages of each type of setup.
After performing a plate and liquid lysate, it was found that the plate lysate achieved the common titre range of 1010-1011 pfu/ml whereas the liquid lysate achieved a range of 108 PFU/mL; what is the reason for the lower titre in different methodologies? How can we troubleshoot this issue in the future?
Someone want to you an antimicrobial agent that leads 99.999% inactivation when the initial microbial load was 10^7 CFU/mL.Firstly can you determine the experimental set-up. Clarify the dilutions you made and show the viable number of CFU from each dilution.
The following are errors that people commonly make when they perform serial dilutions. Indicate whether you think that the number of cfu/ ml calculated would be too high or too low if you make this mistake. You intend to add 0.9 ml of diluent to each tube and 0.1 ml of culture. Instead, you add 0.5 ml of diluent to each tube and 0.1 ml of culture to the first tube. Then, you make a serial dilution of 0.1 ml into and from each tube as described. You prepare 0.9 ml of diluents in each tube. You add 0.1 ml of culture (from the overnight culture provided) to every tube. You add 0.9 ml of diluent to each tube. You add 0.1 ml of culture to the first tube and mix. You get distracted, and transfer 0.1 ml to the third tube instead of the second. You perform the rest of the series as described.
