Study Notes
Bacterial Growth Factors
- Nitrogen, phosphorus, and sulfur are necessary in large quantities for the biologic synthesis of new organisms.
- Iron is an essential growth factor for many bacteria, and some bacteria require specific vitamins or amino acids to grow.
Effects of Gases on Bacterial Growth
- Oxygen influences the growth of bacteria, with some bacteria requiring oxygen to grow (obligate aerobes) while others are inhibited or killed by oxygen.
- Obligate aerobes, such as Pseudomonas, can grow only in the presence of oxygen.
Temperature and Bacterial Growth
- Almost all bacteria pathogenic to humans have an optimum growth temperature of around 37°C (98.6°F), which is near human body temperature.
