Homework Answers
ANSWER
* In the case of typical bacteria it's biological membarine is complex and composed
of lipids and proteins.
* If the bacteria culture is tested using change in temperature (15 degree celsius to 37 degree celsius).
then their membrane adapt to low temperature by increasing the ratio of unsaturated fatty acid to
saturated fatty acid.
* This type of adaptation known as homeoviscous adaptation and it help to keep the membrane fluidity.

Membrane's regulation Problem 4 (20 pts) - A culture of bacteria growing at 37°C was shifted to 25°C. How would you expect this shift to alter the fatty acid composition of the membrane phospholipids? Explain. If bacteria were able to synthesize cholesterol, how would you expect this shift to alter their membrane's cholesterol concentration?

1) Acetic acid is produced using bacteria in batch culture. It was shown that for each mole of glucose utilized by the bacteria, 3.60 moles of cells, 1.10 moles of acetic acid, 1.30 moles of gaseous CO2, and some H20 are formed. Oxygen and ammonia were consumed. Other components of the system such as phosphate can be neglected.
