Question

Role of vitamins and minerals in fermentation media

Answer 1

Crude media contains high level ofnutrients, vitamins, proteins, growth factors, anti-foaming agents and precursors. It is important to ensure that crude media should not contain toxic substances that could effect the growth of bacteria and yield of product.

Answer 2

In a fermentation process, the choice of the most optimum micro-organisms and fermentation media is very important for high yield of product. The quality of fermentation media is important as it provides nutrients and energy for growth of micro-organisms. This medium provides substrate for product synthesis in a fermentor.

Fermentation media consists of major and minor components.

Major components include Carbon and Nitrogen source.

Minor components include inorganic salts, vitamins, growth factors, anti-foaming agents, buffers, dissolved oxygen, other dissolved gases, growth inhibitors and enzymes.
