saccharophagus degradans saccharophagus degradans saccharophagus degradans (formerly microbulbifer degradans) is a gram-negative marine bacterium known to degrade a number of complex polysaccharides as energy source. s. degradans have also been shown to ferment 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. saccharophagus degradans scientific classification domain: bacteria phylum: pseudomonadota class: gammaproteobacteria order: cellvibrionales family: cellvibrionaceae genus: saccharophagus species: s. degradans binomial name saccharophagus degradansekborg et al. 2005 synonyms microbulbifer degradans
