It is proposed that the asaccharolytic strains (guanine-plus-cytosine content, 50 to 54 mol%) should be assigned to a separate species, Bacteroides asaccharolyticus, whereas the saccharolytic strains (guanine-plus-cytosine content, 40 to 45 mol%) should still be classified in the two subspecies Bacteroides melaninogenicus subsp. melaninogenicus and Bacteroides melaninogenicus subsp. intermedius, although further study is required to complete the characterization of these two groups., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-27-4-388
