A medium was inoculated with 5 * 106 cells/ml of Escherichiacoli cells. Following a 1-h lag, the population grewexponentially for 5 h, after which the population was 5.4 * 109cells/ml. Calculate g and k for this growth experiment.
N. benthamiana will be infiltrated with a solution containing OD600=0.3 of each experimental Agro containing construct and OD600=0.1 of p19. Calculate the volume of cultures (V construct; V p19) needed according to the formulas: V construct = V final × 0.3/OD600; V p19 = V final × 0.1/OD600. One mL of infiltrate is often enough to complete a small experiment. How to plan your final volume accordingly?
You were assigned to investigate a poor production problem in one of the aquaculture site of thecompany that you are working. The overall fish production is not making any profit. You made aninvestigation on every part of the operation and appears to be normal and standard protocols had beenfollowed. You ordered a feed analysis and the data is presented below in terms of essential amino acidprofile of the diet: 1. Based on this dietary profile, describe the possible disease that could happen to the fish stockand elucidate the signs of this disease.2. Also discuss how this disease could cause losses in production operation.3. Design and describe a solution to resolve this production problem.
Which of the following types of data produce curves similar in shape to the graph? Select all that apply 1.Bacterial growth in a culture 2.A normal distribution of height in a population of students 3.Exponential population growth 4.Haemoglobin binding of oxygen 5.Log transformations of drug dose curves 6.Osmotic fragility of red blood cells 7.A standard curve for an enyme assay
If a bacterial species is not susceptible to an antibacterial drug at the concentration present in a particular disk, does that necessarily mean the species is completely resistant to the drug? Explain your answer. What is the mode of action of bacitracin? How does this influence the types of bacteria it can be used against effectively? What is the mode of action of tetracycline? How does this influence the types of bacteria it can be used against effectively? Describe how populations of bacteria can evolve resistance to antibiotics. In your description, use the terms/phrases: mutation, resistant, sensitive, individuals, populations, natural selection, horizontal gene transfer.
The UWC Biotechnolo class undertook a study to determine the microbiological quality of mince-meat samples that were obtained from four local retail outlets. You have performed the following serial dilution of the mince samples. Firstly, 25 g of the minced samples was transferred to 225 ml 4 strength Ringers'-solution, followed by two (2) 10-fold dilutions and finally three (3) 100-fold dilutions. These dilutions were then pour-plated out (1000 µl of each) onto the required medium. The colony forming units (cfu) for the Enterobacteriaceae count is listed in the table below: 1 3 4 6.

Use the following passage to answer 2 consecutive questions. A urine specimen was collected in a container and placed on the central desk for delivery at 10:00 am. The specimen is not sent to the lab until 5 hours later (3:00 pm). The sample time was marked by the central clerk as collected at 4:00 pm. The bacterial species has a generation time of 30 minutes at room temperature. There are 100 bacterial cells/ml at the time of collection (10:00 am). The laboratory will cite a bacterial infection at more than 1000 bacterial cells/ml.
In the antibiotic disc diffusion study, the "Minimal Inhibitory Concentration" or MIC of the antibiotic was in the agar in the agar furthest away from the antibiotic disc O halfway between the disk and the border of the zone of inhibition directly under the antibiotic disc at the border/edge of the zone of inhibition
Suppose you spilled two cultures of Salmonella typhimur-ium (each containing 100,000 cells) on your lab bench. You im-mediately applied the same disinfectant to both cultures at thesame time. One culture had been freshly grown for 36 hours andthe other culture is 2 weeks old. If the kill ing rate of the disin-fectant is 90% per minute, do you think that microbes in bothcultures will be completely killed after 6 minutes? Why or whynot?
A patient presents with sepsis from an E.coli bacteremia (bacteria growing in bloodstream). E. coli is a Gram-negative Enterobacteriaceae. You perform antibiotic sensitivity tests using the Kirby Bauer disc diffusion technique. The diameter of the zone of Inhibition for Ampicillin is for the E. coli is 17 mm. Is the E.coli strain sensitive, intermediate or resistant to ampicillin at therapeutic levels? Zone of Inhibition Diameter Interpretive Chart in mm for Ampicillin Resistant Intermediate Sensitive Enterobacteriaceae 17 >29 Staphylococcus <28

Two microorganisms that use naphthalene as a food source have the same Umax but different Ks values for naphthalene. If both types of microorganisms are inoculated at the same cell density into a liquid culture containing naphthalene as the sole carbon source (i.e. the only food source), which microorganism will outcompete the other: the one with the higher Ks or the one with the lower Ks. Why?.
