Desulfotomaculum nigrificans degraded glucose to acetate, ethyl alcohol, and carbon dioxide. By use of '4C-glucose labeled at different carbon atoms, two pathways of glucose metabolism were detected. They were the Embden-Meyerhof and the Entner-Doudoroff schemes. Because the observed quantities of acetate and carbon dioxide, arising from glucose, were greater than the expected theoretical values, individual fermentations were conducted with 15 uniformly labeled "4C-amino acids. The results indicated that amino acids, supplied by the yeast extract or peptone in the fermentation medium, also contributed to the formation of acetate and carbon dioxide.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
