Explain why a buccal swab procedure should not cause bleeding. 9. The tight junctions between the epithelial cells prevent blood from leaking out into the oral cavity. The cells removed are dead and therefore cannot bleed There are no blood vessels in the buccal region that can be broken Epithelium is avascular. Removing a few cells from the apical layer of the epithelium will not damage any blood vessels. Submit Request Answer

c) Lactobacillus casei is propagated under essentially anaerobic conditions to provide a starter culture for manufacture of Swiss cheese. The culture produces lactic acid as a by-product of energy metabolism. The system has the following characteristics: Yx/s 0.23 kgkg Ks0.15 kg/m Hmax 0.35/h ms 0.135 kg/kg.h A stirred fermenter is operated in fed-batch mode at quasi-steady state witha feed flow rate of 3 m/h and feed substrate concentration of 60 kg/ m3. After 6 h, the liquid volume is 30...

A strain of Streptococcus pyogenes isolated from a throat swab was tested for sensitivity to ampicillin and tetracycline. The following results were obtained: Zone of Inhibition around ampicillin disk = 25 mm Zone of Inhibition around tetracycline disk = 21 mm Explain why the physician prescribed tetracycline instead of ampicillin. FOR FURTHER RESEARCH Most microorganisms that cause disease in humans are mesophiles. However, poorly maintained hot tubs can be a source of thermophiles that can cause human infections. List at...
