The nicotinamide adenine dmucleotide-specific isocitrate dehydrogenase of yeast was reported by Kornberg and Pricer (1) to have an absolute requirement for adenylic acid and not to catalyze the reverse reaction under conditions suitable for such catalysis by the nicotinamide adenine dinucleotide phosphatespecific enzyme. Similar results have been obtained for the nicotinamide adenine dinucleoti...

The possibility of immobilization of Acetobacter suboxydans cells by entrapment within polyacrylamide gels or by intercellular cross-linking with glutaral-dehyde was investigated. The oxidation of unsubstituted alditols and aldose diethyl dithioacetals by the resultant modified cells has been achieved.

Because of the high energy consumption for fermentor cooling, the isolation of thermo-tolerant Acetobacter strains for vinegar production has a high priority. The aims of this study were the isolation and identification of a high ethanol-thermo-tolerant Acetobacter spp. from grapes as well as the optimization of conditions for increasing the acetic acid production. The grape e...

A metagenome wide association (MGWA) study of bacterial host association determinants in Drosophila predicted that LPS biosynthesis genes are significantly associated with host colonization. We were unable to create site-directed mutants for each of the predicted genes in Acetobacter, so we created an arrayed transposon insertion library using Acetobacter fabarum DsW_054 isolated from Drosophil...

Bacterial cellulose is produced by several species of Acetobacter and because of its unique properties; it has advantages over plant cellulose. Today, this biopolymer has numerous applications at many industrial fields. In this research, samples from different sources of Iran were collected and cultivated in an enrichment liquid medium for growth of acetic acid bacteria. After purification the ...

1. The growth characteristics of nine micro-organisms on complex broth and defined media, usually with a single nitrogen source (other than vitamins), were examined as a necessary step before growth of cells for enzyme assays. Six of these bacteria gave a positive colour test with a creatine-potassium hydroxide reagent, indicating the presence of acetoin, which other investigators have shown is...

Acetobacter pasteurianus (Ap) CICC 20001 and CGMCC 1.41 are two acetic acid bacteria strains that, because of their strong abilities to produce and tolerate high concentrations of acetic acid, have been widely used to brew vinegar in China. To globally understand the fermentation characteristics, acid-tolerant mechanisms and genetic stabilities, their genomes were sequenced. Genomic comparisons...
