what sugars do bacteria ferment
The types of sugars that bacteria are able to ferment as well as the end products produced are important characteristics used in the identification of bacteria. The number and types of sugars that a given microbe can assimilate will determine to a large extent the environments in which it can survive and grow.acillus subtilis can ferment more than one type of sugar, such as sucrose and dextrose, but cannot ferment other types of sugars, such as lactose. B. subtilis is a gram-positive rod often found in soil and decomposing organic matter; it is a common laboratory contaminate.
1 Glucose is a sugar from which most common chemoheterotrophic bacteria can obtain energy by fermentation and/or respiration. 2  Glucose can also be utilized as a source of carbon, but these media include a large number of potential carbon sources (amino acids as well as glucose), and whether or not glucose is used as a.or this test we routinely use a  Glucose Fermentation Broth 1  .. Fermentation of glucose results in the abundant production of acidic end products, the presence of which can be detected by the pH indicator in the medium. 2  Many organisms produce gas â either CO 2 alone or a mixture of H 2 and CO 2.
