“…The increase in oxygen uptake that resulted from its addition was greater than any that occurred in the presence of any of the substrates used, including carbohydrates. It would appear as though sodium azide had stimulated the oxidation of some stored substrate, an effect closely resembling the effect of 2:4-dinitrophenol on the respiration of rhizobia as reported by Burris and Wilson (1942).…”

The fungi causing the deep mycotic infections of man represent an extremely interesting group of microorganisms. Among them there are several species, notably Blaatomyces dermatitidis and Histoplasma capsulatum, possessing a diphasic morphology. In tissue and on culture media at 37 C they exhibit a yeastlike form. On culture media at room temperature they grow in a filamentous phase. Bermheim (1942) studied the oxidative metabolism of the yeast phase of B. dermatitidis. The effect of various substances upon the oxygen uptake of this organism was determined at pH 6.7 with unstarved cells. He observed that glucose, mannose, pyruvate, and lactate were oxidized, whereas arabinose, rhamnose, and fructose were not. Acetate was oxidized. The higher fatty acids, oleate, palmitate, and stearate inhibited endogenous respiration and also the oxidation of added glucose, pyruvate, lactate, and acetate. Succinic acid was slowly oxidized, the oxidation being inhibited by malonate. Fumaric acid did not act catalytically, nor did citric acid, which was not oxidized. Sodium cyanide completely inhibited the oxidation of all added substances. Bernheim also studied the effects of aldehydes and amino acids on the respiration of B. dermati-1 This work is part of a thesis presented by Seymour Levine to the Graduate College in partial fulfillment of the requirements for the degree of Doctor of Philosophy.

Many studies have been made on assimilation during the growth of microorganisms. With non-proliferating cells, however, it is not generally appreciated how great the assimilation may be in a relatively short period of time. Fiirth and Lieben in 1922, for example, found that about half of the lactic acid disappearing from an aerated yeast suspension in the course of a few hours was converted to a "hydrolysis resistant carbohydrate." The following year Lieben ( '23) also showed that pyruvate is in part decomposed with carbon dioxide production, in part utilized in the formation of "body substance." This was confirmed by Smedley-MacLean and Hoffert ('26) who found the fat and carbohydrate content of yeast cells increased with lactate, pyruvate, acetate, or ethanol as substrate. Acetaldehyde, however, as well as acetoacetate, butyrate, 0-hydroxybutyrate, glycerol, and acetone, was poorly or not a t all utilized. That acetaldehyde was not utilized is surprising since this compound is known to be an intermediate in the fermentation cycle. It appears quite possible that the acetaldehyde was added in an inhibitory concentration, for Wieland and Claren ('32) later showed the rate of oxidation of this compound is inversely proportional to the concentration between M/3 and M/120. With lower concentrations -M/120 to M/180 -Wieland and Claren found a dismutation of the acetaldehyde to ethaflol and acetic acid, the latter compound being slowly oxidized to carbon dioxide and water.Cook and Stephenson ( '28), using suspensions of Alcaligenes faecalis and Escherichia coli, reported that the amounts of oxygen consumed in experiments involving small quantities of substrates such as glucose, lactate, and acetate were only from two-thirds to three-fourths of the amounts necessary for complete oxidation.
