Options:
Controlling environmental conditions
Use of chemicals
Both a and b
Killing micro-organisms
• Bacteriostatic methods aim to inhibit the growth and reproduction of bacteria without necessarily killing them. This can be achieved through:
✏Controlling environmental conditions:
-Temperature: Refrigeration slows down bacterial growth.
-pH: Creating acidic conditions can inhibit bacterial growth (e.g., pickling).
-Oxygen availability: Controlling oxygen levels can limit the growth of certain bacteria.
-Nutrient availability: Limiting access to nutrients can prevent bacterial proliferation.
🔑Key Points:
-Antibiotics are naturally or synthetically produced chemical compounds that fight against bacterial infections.
-The antibiotic that prevents bacterial infection by destroying the bacterial microorganisms is identified as bactericidal.
-For example, penicillin, aminoglycosides, and ofloxacin.
-The antibiotic that prevents bacterial infection by inhibiting the growth of bacterial microorganisms is identified as bacteriostatic.
-For example, erythromycin, tetracycline, and chloramphenicol.
