TL;DR: The results show that the tricarboxylic acid cycle plays a significant role in the metabolism of succinate apart from its essential biosynthetic role.

TL;DR: The present study was undertaken in an effort to detect a tricarboxylic acid cycle in Pseudomonas aeruginosa and thereby to elucidate further the pathway of glucose oxidation in this organism.

TL;DR: Most work on this problem has been concentrated on bacterial glycogen and useful information on the factors affecting the accumulation and utilization of this storage product has been reported but the nature of the reserve material has practical importance from another point of view.

TL;DR: The literature contains seemingly conflicting reports regarding the influence of zinc, iron, copper, and manganese on the production of citric acid by Aspergillus niger; in fact, the fermentation media used by many workers has not included any of these elements other than as chance contaminants.

TL;DR: A linear response of phosphate-starved cells to low levels of phosphate supplied exogenously was evident from optical-density measurements, and a threshold requirement for phosphate analogous to the "energy of maintenance" was not detected.
