The Bacteriological Media Ingredients can be water, nitrogen source, carbon source, oxygen (or other electron acceptor), energy source, minerals, vitamins, and trace biochemicals. These can use glucose as energy as well as carbon sources. Functional as a highly capable energy source, these can oxidize one molecule and employ another as electron acceptor; thus, they are not able to obtain as much energy as would be available were the energy oxidized completely to carbon dioxide and water. These can make almost everything them need, but need a long list of vitamins and required factors. Bacteriological Media Ingredients can also be employed in food processing procedures.
