Phosphate accumulation of Acetobacter xylinum

Archives of Microbiology, 2009
The cells of Acetobacter xylinum decreased phosphate concentration in the medium from 5 to 2.5 or 0.3 mM during incubation in the presence of Mg(2+) and glucose, or Mg(2+) and casamino acids, respectively. The prevalence of orthophosphate or polyphosphate in the biomass of A. xylinum depends on the medium composition.

THE LYSIS OF ACETOBACTER XYLINUM

Canadian Journal of Microbiology, 1962
Lysis of about 90% of the cells of Acetobacter xylinum by lysozyme may be obtained after 2 hours at pH 8.1 in phosphate–citrate buffer. The cell population is heterogeneous since the remaining 10% of the cells do not lyse, even on repetition of the above treatment.

Regulation of Gluconeogenesis in Acetobacter xylinum

European Journal of Biochemistry, 1972
Gluconeogenesis in the form of cellulose synthesis from succinate and pyruvate has been studied in resting cells of Acetobacter xylinum. Substrate utilization and cellulose formation occurred at linear rates. At saturating levels of substrate the rate of cellulose formation from succinate was two to three times that from pyruvate.

The biosynthesis of cellulose by Acetobacter xylinum and Acetobacter acetigenus

Canadian Journal of Microbiology, 1977
The morphological aspects of biosynthesis of cellulose by Acetobacter xylinum and Acetobacter acetigenus were studied by transmission electron microscopy of both freeze-etch replicas and sections of cellulose-free cells in suspension culture before and subsequent to the induction of cellulose synthesis.

Regulation of gluconeogenesis in Acetobacter xylinum by hexoses

Biochemical and Biophysical Research Communications, 1971
Abstract Cellulose formation in Acetobacter xylinum occurs at a similar rate when either glucose, fructose or succinate are added as the source of carbon. When either glucose or fructose are added in addition to succinate, cellulose formation from succinate is decreased by 80%.

Biosynthesis of a novel polysaccharide by Acetobacter xylinum

International Journal of Biological Macromolecules, 1994
An Acetobacter xylinum adapted to a medium containing N-acetylglucosamine (GlcNAc) has been used to prepare a novel polysaccharide containing residual GlcNAc in cellulose. The maximum amount of incorporation was found to be 4 mol% in cellulose, when a mixed medium containing 1.4% glucose (Glc) and 0.6% GlcNAc was used for the culture of A. xylinum. The
