If you were to ask someone what role fungi played in industry, it is likely that they would indicate use of yeasts in brewing, wine making and bread making. This response is probably related to their level of awareness of yeasts in brewing and baking, rather than their understanding of the importance of fungi in industry. Brewing and baking rely upon a simple principle. The basis of current industries has been around for many centuries. Fermentation commonly results in the release of alcohol, but lactate, glycerol and other organic molecules can also be released. The principles are simple and well understood.
