Investigations into the nature of the metabolism of glucose in Acetobacter suboxydans have revealed that both the pentose cycle (1) and a direct nonphosphorylative oxidation (2) contribute to the consumption of this substrate. Fructose, in like manner, dissimilates by way of the pentose pathway (3) as does glycerol, after its conversion to fructose-l ,6-diphosphate via triose phosphate (1,4). S...

Benziman, Moshe (The Hebrew University of Jerusalem, Jerusalem, Israel), and A. Abeliovitz. Metabolism of dicarboxylic acids in Acetobacter xylinum. J. Bacteriol. 87:270-277. 1964.-During the oxidation of fumarate or l-malate by whole cells or extracts of Acetobacter xylinum grown on succinate, a keto acid accumulated in the medium in considerable amounts. This acid was identified as oxaloaceti...

The cu-ketoglutarate dehydrogenase complex of Acetobacterxylinum was purified to homogeneity. It consists of three main polypeptide chains with a total molecular weight of about 2.4 x 106. It catalyzes the overall Mg*+ and thiamin pyrophosphate-dependent, NAD+and CoA-linked oxidative decarboxylation of cY-ketoglutarate, as well as the partial reactions characteristic of the three enzyme compone...

Mediterranean spotted fever in liver trans-plantation: a case report. To the Editor: Unusual and multiresistant bacterial infections are increasingly reported in cystic fi bro-sis (CF) patients (1). On January 25, 2007, a 31-year-old man with CF (mutation ΔF 508 and I 507) was admitted to our institution in Marseille, France, for lung transplantation. His immuno-suppressive regimen included IV ...

Twenty-six strains of acetic acid bacteria were isolated from fruits, flowers and related materials collected in Thailand. They were divided into three genera, Acetobacter, Gluconobacter and Asaia, by phenotypic characterization and 16S rRNA gene sequence analyses. On the basis of 16S-23S rRNA gene internal transcribed spacer (16S-23S rDNA ITS) restriction and 16S rRNA gene sequence analyses, f...

For some years evidence that 2-keto-D-gluconic acid is implicated in a number of biochemical systems, notably in Acetobacter species (Bernhauer & Gorlich, 1935; Kulka & Walker, 1954) and in Pseudomonas species (Lockwood, Tabenkin & Ward, 1941; Norris & Campbell, 1949) has been accumulating. Studies by Warburg & Christian (1937) with red blood cells, by Lipmann (1936) with yeast macerate prepara...

Two-dimensional gel electrophoretic analysis of the membrane fraction of Acetobacter aceti revealed the presence of several proteins that were produced in response to acetic acid. A 60-kDa protein, named AatA, which was mostly induced by acetic acid, was prepared; aatA was cloned on the basis of its NH2-terminal amino acid sequence. AatA, consisting of 591 amino acids and containing ATP-binding...

Acetobacter species have been used for brewing traditional vinegar and are known to have genetic instability. To clarify the mutability, Acetobacter pasteurianus NBRC 3283, which forms a multi-phenotype cell complex, was subjected to genome DNA sequencing. The genome analysis revealed that there are more than 280 transposons and five genes with hyper-mutable tandem repeats as common features in...

Acetobacter strains able to produce a thick pellicle at 37 degrees C were screened among many thermotolerant strains isolated from fruits in Thailand. As a result, Acetobacter sp. SKU 1100 was selected as the producer of a relatively thick pellicle even when cultured at higher temperatures such as 37 degrees C or 40 degrees C. This strain could produce a pellicle polysaccharide in a shaking sub...
