Saccharophagus degradans (formerly Microbulbifer degradans) is a bacterium which can perform the function of fermenting xylose to ethanol. In recent studies, Saccharophagus degradans from Chesapeake Bay was effectively used to produce cellulosic ethanol. Cellulosic ethanol production by means of bacterial action could be the key cheap production of cellulosic ethanol for global mass market production of bioethanol. It is currently produced by such means as gasification. S. degradans is the only species in its newly created genus.
