LABORATORY REPORT: Aseptic Technique & Inoculation of Bacteria Guide Questions. 1. Why is direct flaming preferred when disinfecting loops and needles? 2. Why is it important to flame the entirety of the loop and not just the tip? What consequences can be seen when this process is not done correctly? 3. What is the difference between quadrant streak method A from method B? 4. Why do we use a pencil instead of a pen when labelling culture tubes or plates? Are there other alternatives in labelling? 5. Why is an inoculating needle used in Subculturing Techniques? Can a loop be used instead? NOTE: Please try to answer all of the question asked, i promised to give you a good ratings

Enumeration Questions: 1. You dilute an original sample 1:50. You then count the number of yeast cells in the 1:50 dilution. You count an average of 15 cells in the 1/25 mm2 sized boxes. What is the density, in cells/mL, of the original sample? 2. You count 91 cells in 7 of the 1/400 mm2 small boxes of the central grid on the hemocytometer. You are counting a 1:100 dilution of the original sample. What is the density of the original culture (in cells/mL) 3. You count 116 CFU on a pour plate. The plate was prepared by spreading 0.1 mL of a 1:10,000 dilution of the original sample. What is was the density of the original culture (in cells/mL)? 4. You have a culture of yeast that is at a density of 8x107 cells/mL. You dilute the sample 1:10, then 1:1,000 again, and finally you dilute the sample an additional 1:5. You add 0.1 mL of the final dilution to a spread plate. Assuming that most of the cells forming units do you expect to count on your pour plate the next day? the original culture…
