microbial sensivity lab: in the procedure used to test bacterial growth against various temperatures (incubator, room, refrigerator, freezer), why should efforts be made to inoculate each tube with the same number of bacteria?

Instruction: answers must be in numbers. You are culturing bacteria using a petri dish, the bacteria grow very well on this plate you have. However, your microbiology instructor wants to know how many bacteria per milliliter (bacteria/mL) are on your plate. And as you have remembered during the first day of inoculating this bacteria you used a imL aliquots sample of a 1:10,000 dilution, and the total colony you counted on this plate is 170. How many bacterial per milliliters would that be?

Before viewing a specimen of pigmented bacteria on a slide under the light microscope, which of the following usually needs to happen (and why)?     Staining (to increase magnification).     Heat, radiation or antimicrobial chemical treatment (to kill the bacteria for safe observation).     Add immersion oil (to increase resolution).     Add a cover slip (to reduce contamination).     The viewing chamber needs to be flushed of air (to create a vacuum).

Helping tags: Biology, Food Microbiology, Spore formers, sulfide spoilage spores 25 g of sugar sample was obtained from the production line for analysis of raw ingredients. It was diluted to 250 ml and was heated at 100 deg Celsius for 5 minutes. After cooling, 20 ml of the sample solution was divided equally among 6 tubes of sulfite agar. After incubation, the following counts were obtained: 35, 26, 29, 32, 34, and 31. Compute for the number of sulfide spoilage spores and express the count per 50 g of sugar.  . . .

Greetings :) Based on the results of using Hanging-drop method in Figure 2, what microorganisms can you find? Kindly state or identify all microbes you can see, and briefly described each of them. Thank you so much!

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”.

Please use this submission link to submit your flowcharts. You will need to submit a total of three flowcharts, one for each of your unknown microorganisms (gram positive rod, gram positive coccus, and gram negative rod).
