Write three to five sentences about Escherichia Coli bacteria. Such as the shape of the bacteria, gram stain, diseases that can be caused by this bacteria, and etc.

Expert Solution

Escherichia coli (abbreviated as E. coli) are bacteria found in the environment, foods, and intestines of people and animals. E. coli are a large and diverse group of bacteria. They are Gram-negative rod-shaped bacteria, which possesses adhesive fimbriae and a cell wall that consists of an outer membrane containing lipopolysaccharides, a periplasmic space with a peptidoglycan layer, and an inner, cytoplasmic membrane.

Although most strains of E. coli are harmless, others can make you sick. Some kinds of E. coli can cause diarrhea, while others cause urinary tract infections, respiratory illness and pneumonia, and other illnesses.

Researchers grew populations of identical Escherichia coli (E. coli) bacteria in a growth medium that contained a low concentration of glucose and a high concentration of citrate, a substance that is not typically consumed by E. coli. For thousands of generations, the bacteria used only glucose as an energy source and grew relatively slowly (and to a low density because of the low concentration of glucose). After about 30,000 generations, one population emerged that began to rapidly grow to a...

The bacterium Escherichia coli (or E. coli) is a single-celled organism that lives in the gut of healthy humans and animals. When grown in a uniform medium rich in salts and amino acids, these bacteria swim along zig-zag paths at a constant speed of 20 μm/s. The figure shows the trajectory of an E. coli as it moves from point A to point E. Each segment of the motion can be identified by two letters, such as segment BC. For the...

Escherichia coli O157:H7 is a pathogenic strain of E. coli associated with consumption of raw or undercooked foods. When exposed to temperatures above its normal growth temperature (temperatures that do not kill it), it may change its membrane lipid composition to counteract the rise in temperature. Which of the following changes would be most likely? Select one: a. A greater proportion of the unsaturated 16-carbon palmitoleate b. A greater proportion of the saturated 12-carbon laurate c. Generating a thinner membrane...

You are trying to design a protein that will be expressed in Escherichia coli and secreted outside of the cell for purification and use as a pharmaceutical. E. coli is a gram-negative cell and the protein folds after it has exited the cell. Which secretion system would work best for this project? Support your answer with evidence based on the properties of E. coli, the protein and the secretion system.

. Why was Escherichia coli thought to be a dominant member of the human gut microbial community in the past? What populations ARE important in the human gut and what evidence do we have that the specific bacteria present are important for human health?

Part A Escherichia coli (E. coli) can under optimal conditions double every 20.0 minutes. How long would it take a single cell to saturate a 5.0 L culture assuming that optimal growth conditions prevaled and that no cells died? The maximum cell denisty in a saturated culture is 1010 cells mL-1. Enter your answer to the nearest tenth of an hour. Part B Consider the information in Part A and decide how long it would take for the 5.0 L...
