Study Notes
Microbial Characteristics
- Shape: Refers to the physical form of a microbe, which can be spherical, rod-shaped, spiral, or irregular.
- Size: Relates to the measurement of a microbe's dimensions, which can vary greatly between species.
- Motility: The ability of a microbe to move on its own, which can be achieved through flagella, cilia, or gliding.
- Gram Staining: A method of differentiating microbes based on their cell wall composition, resulting in either Gram-positive or Gram-negative staining.
Microbial Diversity
- Species Richness: The number of different microbial species present in a given environment.
- Community Composition: The variety of microbial species and their relative abundance in a specific ecosystem.
- Functional Diversity: The range of metabolic processes and ecological roles performed by microbes in a given environment.
Time-Related Information
- Generation Time: The time required for a microbe to complete one reproductive cycle.
- Lag Phase: The initial phase of microbial growth, characterized by slow growth and adaptation to the environment.
- Log Phase: The exponential growth phase of microbial growth, where cell division occurs rapidly.
Observing Microbial Diversity
- Microscopy: The use of light or electron microscopes to visualize microorganisms.
- Cultivation: The growth of microbes on artificial media, allowing for the isolation and characterization of species.
- Molecular Techniques: The application of genetic analysis, such as PCR or DNA sequencing, to study microbial diversity.
