Abstract In the fermentation ofl-aspartate by a free-livingCampylobacter spec., the products formed were acetate, succinate, carbon dioxide and ammonia. The oxidative part of the fermentation pathway yielded acetate, succinate, carbon dioxide and ammonia, and the reductive part gave rise to the formation of succinate and ammonia. When grown anaerobically with aspartate, cells contained cytochromesb andc as well as menaquinone. Reduced cytochromeb, but not reduced cytochromec could be reoxidized by fumarate. In the presence of nitrate, 90% of the available electrons were transferred to nitrate, which was reduced to nitrite; the remainder was transported via the fumarate reductase system. Cells grown with aspartate and excess of formate converted aspartate quantitatively to succinate.
