The mechanism of acetate assimilation by the purple nonsulfur bacterium Rhodobacter sphaeroides, which lacks the glyoxylate shortcut, has been studied. In a previous work, proceeding from data on acetate assimilation by Rba. sphaeroides cell suspensions, a suggestion was made regarding

Itaconate is known as a potent inhibitor of isocitrate lyase. Unexpectedly, itaconate was a strong inhibitor of acetate and propionate assimilation in isocitrate lyase-negative purple non-sulfur bacterium Rhodospirillum rubrum. It was shown that in cell extracts of R. rubrum itaconate

The photosynthetic green sulfur bacterium Chlorobaculum tepidum assimilates CO(2) and organic carbon sources (acetate or pyruvate) during mixotrophic growth conditions through a unique carbon and energy metabolism. Using a (13)C-labeling approach, this study examined biosynthetic pathways and flux distributions in

Cyanothece sp. ATCC 51142 is an aerobic N(2)-fixing and hydrogen-producing cyanobacterium. Isotopomer analysis of its amino acids revealed an identical labelling profile for leucine and isoleucine when Cyanothece 51142 was grown mixotrophically using 2-(13)C-labelled glycerol as the main carbon source.
