Basic Methods of Studying Microorganisms

These flashcards encompass fundamental vocabulary and concepts related to the study of microorganisms, including methods, growth phases, and aspects of culture media.

Morphological Methods

Approaches that study the form and structure of microorganisms.

Cultural Methods

Techniques that involve growing microorganisms in controlled environments.

Biochemical Methods

Processes used to analyze metabolic activities of microorganisms.

Generation Time

The time required for a bacterial cell to divide, often measured in hours.

Aseptic Techniques

Procedures performed under sterile conditions to prevent contamination.

Lag Phase

The initial phase of microbial growth where bacteria adapt to their environment.

Log Phase

The phase of rapid microbial growth during which cells divide exponentially.

Stationary Phase

A phase where the rate of bacterial growth equals the rate of cell death.

Death Phase

Phase where the number of dying cells exceeds the number of new cells produced.

Selective Media

Culture media designed to encourage the growth of specific microorganisms while inhibiting others.

Differential Media

Media that contain indicators to differentiate between microbial species based on their metabolic capabilities.
