Homework Answers
As different microbes and growth enzymes are temperature sensitive. The maximum growth occurs at optimal temprature. This case the optimal temperatue is 35oC for mesophiles. and 10oC for psycophiles.

Bacterium "X" was grown in L-broth with shaking at 35°C to determine the growth rate (k) of that organism at that temperature. The growth rates of that bacterium grown at other temperatures were also determined, and all of the data was plotted in the graph shown below. Growth Rate (k) 15 20 25 30 35 40 45 50 Temperature (°C) The next graph shows just the exponential phase of growth of Bacterium "X" grown at 35°C, 40°C and 45°C. Note:...

2. You are given a mixed broth culture of Pseudomonas fluorescence (Gram-negative) and Clostridium sporogenes (Gram-positive). You are instructed to isolate and purify each bacterial species. How are you going to do it? Your goal is to have a plate of pure P. fluorescence with isolated colonies and a plate of pure C. sporogenes with isolated colonies. Explain in detail how you are going to perform the exercise. You can use any media you like such as nutrient agar plate,...

Question 1 (1 point) An unknown organism was inoculated into a phenol red tub and produce a yellow coloration. The same organism was inoculated into a purple broth tube resulted in growth after the incubation period. Green slant tubes were also inoculated and resulted in a blue coloration. However, this organism was negative for motility within a SIM tube. Which of the following is the unknown species? Salmonella typhimurium Shigella sonnei Enterobacter aerogenes Klebsiella pneumoniae Escherchia coli O Proteus mirabilis...

Read each question carefully. Write your response in the space provided for each part of each question. Answers must be written out in paragraph form. Outlines, bulleted lists, or diagrams alone are not acceptable and will not be scored. The sex of an organism is typically determined genetically, but environmental factors can also play a role. Scientists examined the roles of genes and environmental temperature in the sex determination of a lizard species. Individuals with aZW pair of chromosomes are always...
