- Convert 14.3mL to microLiters My answer: 14.3 x 10^9 microLitersSupport 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”.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. Milk sample A contained an average of 53 cells per FOV at a dilution factor of 7 whereas Milk sample B contained an average of 99 cells per FOV at a dilution factor of 5. Therefore, milk sample A has less microbial contamination. (Note: 0.01mL of each sample was placed on a clean glass slide and both samples were examined under OIO with an area of 1.77x10-4 cm2.)
