1. Why is 37 C the optimum temperature for E. coli growth?
2. A major medical problem is the ever-increasing number of bacterial strains that are resistant to specific antibiotics. Antibiotic resistance is carried on circular DNA molecules, called plasmids, which are generated separately from the cell’s chromosome. With this in mind, suggest a mechanism through which new antibiotic-resistance strains of bacteria arise.
3. Microbial contamination is caused by:
a. Gown fibers
b. Dead skin cells
c. Bacteria
d. Dust
e. All the above
4. Organism used in the Bioremediation may be native or genetically modified True or false.
