Abstract:
Microorganisms are important for many reasons. Because, they produce things that are of value to us. These can be very large materials (e.g. proteins, nucleic acids, carbohydrate polymers, even cells) or smaller molecules and divided into metabolites that are essential for vegetative growth (primary) and those that are non-essential (secondary). Microbial technology has made significant advances in recent years with it’s impact on the society. For thousands of years microorganisms have been used to supply products such as bread, beer and wine. A second phase of traditional microbial biotechnology began during World War I in the development of the acetone-butanol and glycerol followed by citric acid, vitamins and antibiotics.
