A thorough solution comparing the cell walls of gram-positive and gram-negative bacteria. Solution includes relevant theory pertaining to the nature of the gram stain and detailed explanations of all related questions.
General Microbiology (Bacteria, Energy Production, DNA etc.)
A number of multiple choice Microbio questions. Examples:
#1 Compare and contrast carbohydrate catabolism and energy production in the following bacteria:
a. Pseudomonas, an aerobic chemoheterotroph
b. Spirulina, an oxygenic photoautotroph
c. Ectothiorhodospira, an anoxygenic photoautotroph
#2 The bacterial enzyme streptokinases is used to digest fibrin (blood clots) in patients with arteriosclerosis. Why doesn't injection of streptokinases cause a streptococcal infection? How do we know the streptokinases will digest fibrin only and not good tissues?
