The nutritional requirements of Acetobacter melanogenum and related species.
During the course of some physiological studies with Acetobacter melanogenum it became necessary to investigate the nutritional requirements of several isolates in considerable detail. Grey and Tatum (1944) already had described a minimal medium for growth of one isolate of this species. However, since only one isolate was studied and the nutritional observations were made more or less incident...
متن کاملOxidation of acetaldehyde by Acetobacter suboxydans.
Acetobacter suboxydans has a powerful system for the oxidation of ethanol to acetic acid, as might be expected from the fact that the acetic acid bacteria have long been used for the commercial production of vinegar. Alcohol dehydrogenase in soluble extracts has been found to be DPlSspecific1 (1). It has now been observed that either TPN or DPN can be used as coenzyme for the oxidation of aceta...
متن کاملOXIDATIONS BY ACETOBACTER SUBOXYDANS Sirs: Acetobacter suboxydans is known to bring about oxidation of polyhydroxy
Acetobacter suboxydans is known to bring about oxidation of polyhydroxy compounds. The action of the bacterial enzyme is limited, however, to substances with specific configurations. According to the generalization of Bertrand,’ only those hydroxyl groups are oxidized which are situated between a primary hydroxyl group and a secondary one in a cis position. Hann, Tilden, and Hudson,2 in a compa...
متن کاملThe oxidation of d-quercitol by Acetobacter suboxydans.
The oxidation was carried out on a preparative scale with resting bacteria in the presence of oxygen by the technique described in the preceding paper (2). Oxygen uptake under these conditions ceased when about 1.3 atoms of oxygen had been taken up per molecule of d-quercitol. The addition of phenylhydrazine to the reaction mixture resulted in the deposition of a dextrorotatory, crystalline, ye...
متن کاملPhosphorylative and non-phosphorylative oxidation in Acetobacter suboxydans.
It has been shown that glycerol can be oxidized beyond the dihydroxyacetone (DHA) stage by resting Acetobacter suboxydans cells (1). Through washing and centrifuging of the cells at room temperature, most of the oxidative activity was destroyed, which, however, could be restored by the addition of inorganic phosphate and diphosphopyridine nucleotide (DPN). 2,4-Dinitrophenol (DNP), a phosphate “...
