In the development of a fermentation process, the composition of the culture medium plays a major role and will determine to a very great extent the level of end product. For example, a culture medium containing sucrose enables better production of citric acid by A. niger than any other carbohydrate. The pH, temperature of incubation, aeration etc., are all important factors in fermentations and these have to be optimized for each type of fermentation. Emphasis is generally placed on the use of cheap raw materials so that the cost of production is low.
