Study Notes
Microbial Growth and Characteristics
- The number of cells increases as an exponential function of 2n during the logarithmic phase.
- Acidophiles thrive in a pH range that is typically acidic.
- Aerobes are the type of microbe that requires oxygen for growth and survival.
- Facultative anaerobes are organisms that tolerate the presence of oxygen but do not utilize it.
Microbial Environment and Reproduction
- Thermophiles thrive in a temperature range that is typically high.
- Microbial growth is defined as an increase in the number of cells or increase in cellular components.
- A colony in microbiology refers to a group of cells that originate from a single cell.
- The normal reproductive method of bacteria is binary fission.
- Generation time refers to the time required for a cell to divide and form two new cells.
- The generation time depends on factors such as nutrient availability, temperature, pH, and oxygen availability.
