Homework Answers
Solution:
Final dilution plate has 201 colonies.
FDA safety Standard of milk approved 3 X 105 cells per millimeter
That means,
the milk has 2.01 X 104 cells per millimeter (20,000CFU/mL) in the final dilution which is less than 3 X 105 cells per millimeter.
Therefore, this milk is safe to drink.

7. As part of an ongoing monitoring program, you are testing a sample of water from the Chattahoochee River north of Atlanta. Your 10' final dilution (undiluted) plate has 56 Escherichia coli colonies on it. One milliliter was pipetted onto the plate. The EPA safety standards for recreational freshwater state that the water cannot contain more than 235 E. coli per 100 ml. Is the river safe to swim or kayak in? Why or why not?

You have performed a serial dilution of a sample with an unknown concentration of microorganisms. You counted 55 CFU on a countable plate inoculated with 0.1 mL of a 10-3 dilution. What was the population density of the original sample per milliliter? Many of the quantitative methods discussed are popular because they enable the microbiology researcher to selectively count live cells only. Why do you think this might be an important or desirable feature in a medical or environmental research...

A. You have been given a tube of E. coli. You are asked to make 1 mL total volume of 10-1 dilution of the bacterial culture. Explain how you would do this. Show all necessary calculations. ____ ml cells + _____ ml water = 1 ml (total volume) B. Next, you were asked to make a 10-2 dilution of the bacterial sample. Explain how you would perform this. Show all necessary calculations. You have bacteria at a concentration of 2...

Now knowing the MPN value, you decide to do a dilution series in order to figure out the original bacterial concentration of the Swimming Hole, just in case it is not a coliform causing the gastric distress and simply a bacterial overgrowth. You perform the following dilution set: from your 16.3-liter Swimming Hole sample you transfer 10.7 x 10-3 liters into container A which has a volume of 6,250ul, you then transfer 1.7 mL from container A into container B...

IS 3063 Principles of Info Systems CASE TWO—MILK Got Milk? It’s Good for You –Unless it’s Contaminated! Dong Lizhong bet that being a dairy farmer was his golden ticket out of a factory job in china. Unfortunately, a contamination crisis in 2008 shattered his dairy business when babies mysteriously started developing kidney stones from contaminated baby formula. A chemical called melamine, an additive used to make plastic, was discovered in the milk supply of one of china’s thirdlargest dairy producers. Four...

1. You are given a 1 gram soil sample of unknown bacterial load. After doing 10-fold serial dilutions of the soil in sterile water, 100 uL volumes are taken from each dilution for preparation of pour plates. Following incubation, each half of the 10-8 plate has 46 colonies. a) What was the dilution factor? b) How many bacteria were present in the soil? 2. Staphylococcus aureus divides every 20 minutes. A culture begins with 10 bacterial cells. a) After 5...

You are flying to New York. You've been reading the in-flight magazine, which has an article about the physics of flying. You learned that the airflow over the wings creates a lift force that is always perpendicular to the wings. In level flight, the upward lift force exactly balances the downward weight force. The pilot comes on to say that, because of heavy traffic, the plane is going to circle the airport for a while. She says that you'll maintain...

Since the 1980s, HIV (Human Immunodeficiency Virus) has been infecting humans around the world causing the condition known as AIDS (Acquired Immune Deficiency Syndrome). HIV, like all viruses, needs to enter cells and use their machinery to reproduce and spread. During HIV infection, the virus enters specific cells of the immune system (T-cells) by "docking" onto cell surface proteins, including one called CCR5 Genetic analysis of individuals who are naturally immune (resistant) to HIV have revealed that resistance to HIV...
