Food and Beverages
Fermentation plays a key role in the manufacture of various types of food and beverages. One of the products of the process is alcohol, which is why fermentation is a common part of producing wines and beers. Beyond that, microbial fermentation is responsible for the creation of certain dairy products including but not limited to yogurt and kefir. Some of the condiments like fish and soy sauces, sauerkraut, and pickles all make use of fermentation. Before canning became a very popular method of preservation, people had been fermenting their produce.
In some industries they combine the microbes for fermentation with other raw materials. For example, a fermented glucose with carbon can create corn sugar. You can come up with yeast, yeast extract, and cotton seed meal when you mix microbial fermentation with particular growth factors and vitamins.
Sewage Treatment
The various industrial plants do have wastes that need to be disposed, and the disposal often involves putting them at sea. However, because countries are now controlling pollution, many have already implemented more efficient and ethical means of disposing sewage. One of these is through microbiological fermentation. The bacteria consume the sewage, especially the solid ones. If they turn into liquid, sewage plants then treat them in order to kill harmful bacteria that can affect marine life. It’s only after they are cleaned that they are sent into sea.
Agriculture
Fermentation has also been helpful in the production of certain kinds of herbicides and insectides. For instance, insecticides can have Bacillus thuringiensis, which produces protein that are dangerous for the crop-eating insects.
