Metabolites• Metabolites are the
intermediates and products of metabolism.
• The term metabolite is usually restricted to small molecules.
Metabolites• Metabolites have various functions
including– fuel– structure– signaling– stimulatory and inhibitory effects
on enzymes,–defense, and– interactions with other
organisms (e.g. pigments, odorants, andpheromones).
Primary Metabolites
• It is directly involved in normal growth, development, and reproduction.
• Alcohol is an example of a primary metabolite produced in large-scale by industrial microbiology
Secondary Metabolites
• It is not directly involved in those processes, but usually has an important ecological function.
• Examples include antibiotics and pigments such as resins and terpenes .
Primary Metabolites
• Carbohydrates• Proteins• Nucleic Acids• Lipids
Secondary Metabolites
• Alkaloids,
• Terpenoids
• Phenolics
Secondary Metabolites
• Secondary Metabolites are produced in plants is mainly for:– disease resistance (from fungus,
bacteria, viral, and pests),– for pollination and– to combat in extreme conditions of
stress. The stress may be biotic or abiotic [Drought, Cold, Temparature, etc.]
Primary Metabolites
Secondary Metabolites
• Effect of Light• Effect of Incubation Temperature• Effect of pH of the medium• Aeration of the Culture
