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
