Study Notes
Growth Phases and Metabolites
- The production of primary metabolites occurs during the log phase (exponential phase) of microbial growth.
- Primary metabolites are essential for growth and development, including amino acids, nucleotides, and citric acid.
Examples of Primary Metabolites
- Citric acid is a widely recognized primary metabolite due to its central role in cellular metabolism and energy production.
Microorganisms and Secondary Metabolites
- Fungi and certain bacteria are known to be prolific producers of secondary metabolites, which include antibiotics, pigments, and toxins.
- Secondary metabolites often play a role in ecological interactions, such as competition and defense.
Application of Citric Acid
- In the food industry, citric acid primarily serves as a preservative and flavor enhancer, adding a sour taste and preventing spoilage.
Carbon Sources for Citric Acid Production
- Various carbon sources can be utilized for citric acid production, including:
- Glucose
- Sucrose
- Molasses
- Various organic compounds, depending on the microbial strain used.
