Five different strains of E. coli (1, 2, 3, 4 and 5) were streaked onto a series of tester plates. After incubating the streaked plates for an appropriate amount of time, they were scored for growth (+) or no growth (-) of the various strains on each respective plate. MM denotes minimal medium, CM denotes complete medium and letters A, B and C denote the supplements added to minimal medium. Assume supplements A, B and C construct the complete biochemical pathway. The results are shown below. Tester Plate Strain MM MM + A MM + B MM + C CM 1 3 4 Which strain(s) is(are) auxotroph(s)? Choose all correct answers. Select all that apply: a. Strain 4 cross out b. Strain 1 cross out O c. Strain 3 cross out d. Strain 5 cross out e. None of the strains are auxotrophs. cross out f. Strain 2 cross out

A bacterial culture was grown for 12 hours. At 4-hour interval, the culture was sampled to determine the population of the culture, by transferring 25 ml of the suspension to 225 ml 0.90% NaCl. Three consecutive dilutions were further made by using I ml aliquot in 9 ml of 0.90% NaCl. One ml from each dilution was plated in each of duplicate plates. The following table shows the results of the plating method. 田 Sampling COUNTS 1st dilution 54; 61 2nd dilution 3rd dilution 4h dilution 1st 3; 7 0; 0 0,0 2nd TNTC TNCT 242: 233 28: 37 3rd TNTC TNTC INTC 249-246 * TNTC = Too numerous to count i.

In order to determine which dye (Ethidium bromide (10 µg/ml), EvaGreen (10 µg/ml) or SYBR Green (10 µg/ml) is the safest to use in a laboratory for DNA binding, first sterilise the spreader and forceps with 95% ethanol, then place 2-3 drops of bacterial culture on each plate and spread well with a sterile spreader and using the sterile forceps, place a sterile filter disk on the center of each plate. Next, Add a drop of sterile water to the filter paper on the control plate, a drop of ethidium bromide to another plate, a drop of EvaGreen to another plate, and a drop of SYBR green to another plate. The sterile water is used as a negative control. And then incubate the plates at 37°C for 48 hours. The results obtained are attached as a picture, after looking at the results obtained in the picture; use the Ames Assay to determine which of the provided dyes are safest?

Ten grams of hamburger were added to 90 mL of sterile buffer. This was mixed well in a blender. One-tenth of amL of this slurry was added to 9.9 mL of sterile buffer. After thorough mixing, this suspension was further dilutedby successive 1/100 and 1/10 dilutions. One-tenth of a mL of this final solution was plated onto Plate Count agar.After incubation 145 colonies were present. How many colony-forming units were present in the total 10 gramsample of hamburger?
