In this study, lipid fermentation wastewater (fermentation broth after separation with yeast biomass) with high Chemical Oxygen Demand (COD) value of 25,591 mg/L was used as substrate for bacterial cellulose (BC) production by Gluconacetobacter xylinus for the first time. After 5 days of fermentation, the highest BC yield (0.659 g/L) was obtained. Both

Utilization of acetate buffer to improve bacterial cellulose production by Gluconacetobacter xylinus
Food Hydrocolloids, 2016Abstract The bacterial cellulose (BC) pellicle produced from Gluconacetobacter xylinus has many attractive properties to be used in food and biomedical applications. However, the by-product, gluconic acid produced during BC production will decrease the pH of culture that usually leads to a significant decrease of BC production by G. xylinus.

An extensive matrix of different growth conditions including media, incubation time, inoculum volume, surface area and media volume were investigated in order to maximize the yield of bacterial cellulose produced by Gluconacetobacter xylinus, which will be used as reinforcement material to produce fully biodegradable composites. Crystallinity was shown

Gluconacetobacter xylinus (=Acetobacter xylinum) shows variety in acid formation from sugars and sugar-alcohols. Toyosaki et al. proposed new subspecies of G. xylinus (=Acetobacter xylinum) subsp. sucrofermentans in point of acid formation from sucrose and a homology index of 58.2% with the type strain of G. xylinus subsp.

The morphological and supramolecular structures of native cellulose pellicles from two strains of Gluconacetobacter xylinus (ATCC 53582, ATCC 23769) were investigated. Samples had been statically cultivated in Hestrin-Schramm medium containing fully 13C-labeled β-d-glucose-U-13C6 as the sole source of carbon.

To mimic the lignin polymerization process, mats of bacterial cellulose and of a pectin/cellulose composite were used as a host matrix for in vitro polymerization of coniferyl alcohol. A diffusion cell was used to allow the diffusion of both hydrogen peroxide and coniferyl alcohol into the peroxidase impregnated cellulose mats through dialysis ...

Gluconacetobacter xylinus produces extracellularly cellulose under aerobic conditions. The formed bacterial cellulose has gained much attention as temporary substitute for human skin, artificial blood vessels applicable in microsurgery or new material for cartilage replacement.

Organic-inorganic composite materials with different nanotextures have been prepared using three methods based on two nanosized and biocompatible compounds—cellulose Gluconacetobacter xylinus (CGX) and hydroxyapatite Ca5(PO4)3OH (HA). The structure of the initial components and their composites has been studied using the methods of X-ray diffraction ...
