Which of the following statements regarding the proper procedure for using Micropipettes is NOT correct? O a. You cannot use a 2-20 µl micropipette to pipet 200 µl O b. To expel all the liquid from the tip, you have to press the eject button O c. To draw up solution, press and hold the plunger at the first stop before entering the solution O d. Micropipettes always require the use of a disposable plastic tip O e. While pipetting, micropipettes should always be held as straight as possibleThis is a typical lab exam question. (Problem-solving, uses current topic.)Your TA performed the antibiotic disc experiment using supplies from their research lab. The antibiotic discs had the year 2002 written on their containers.Your TA grew a pure culture of unknown bacteria. They applied the culture to a fresh agar plate and applied the 2002 antibiotic discs to the plate and incubated it for growth. They found that the mystery bacteria species was resistant to all three antibiotic discs that were applied to the plate.Are there any control groups that could be used to confirm or refute this multi-drug resistance? Describe them.
- Support your answer using computation-based judgment. Encircle/box your final computed answer in your solutions along with a declaration of TRUE or FALSE for each given situation. UHT-pasteurized milk sample X which was spread-plated in quadruplicates yielded the following bacterial colony counts: 23, 20, 35 and 41 CFU/plate at a dilution factor of 100. Therefore, the milk sample will pass laboratory standards if the quality control laboratory sets the total microbial limit as: “not to exceed more than 30,000 CFU/mL of milk sample”.In this section you will present the results of all the tests that was done to identify your organism Enterobacter aerogenes (your observation). In the laboratory we tabulated our results and created a chart (ID Matrix). Here you are describing the result of each test (in your own words). Include the name of the Indicator used (if any). Color changes that represent positive/negative results must be mentioned here.
