Thin stillage (TS), a wastewater from rice wine distillery can well sustain the growth of Gluconacetobacter xylinus for production of bacterial cellulose (BC). When used as a supplement to the traditional BC production medium (Hestrin and Schramm medium), the enhancement of BC production increased with the amount of TS supplemented in a static culture ...

Gluconacetobacter xylinus possesses a constitutive membrane-bound oxidase system for the use of ethanol. Its alcohol dehydrogenase complex (ADH) was purified to homogeneity and characterized. It is a 119-kDa heterodimer (68 and 41 kDa subunits). The peroxidase reaction confirmed the presence of haem C in both subunits.

The Cells of Gluconacetobacter xylinus Response to Exposure
2013Via direct current (DC) electric field, bacterial cellulose (BC), a biopolymer generated by Gluconacetobacter xylinus, was altered into its nanofibers alignment and 3-dimensional network structure in its synthesized process. In this investigation, cultures of G.

In this study, corncob acid hydrolysate was used as a substrate for bacterial cellulose (BC) production by Gluconacetobacter xylinus. After 2 weeks' static fermentation, a BC yield of 4 g/L could be obtained. Both effects of medium composition and fermentation condition on the BC production were evaluated.

Effective cellulose production by a coculture of Gluconacetobacter xylinus and Lactobacillus mali
Applied Microbiology and Biotechnology, 2006A microbial colony that contained a marked amount of cellulose was isolated from vineyard soil. The colony was formed by the associated growth of two bacterial strains: a cellulose-producing acetic acid bacterium (st-60-12) and a lactic acid bacterium (st-20). The 16S rDNA-based taxonomy indicated that st-60-12 belonged to Gluconacetobacter xylinus and

Gluconacetobacter xylinus (formerly Acetobacter xylinum and presently Komagataeibacter medellinensis) is known to produce cellulose as a stable pellicle. However, it is also well known to lose this ability very easily. We investigated the on and off mechanisms of cellulose producibility in two independent cellulose-producing strains, R1 and R2.

Journal of Bioscience and Bioengineering, 2015
In this study, a novel bioreactor for producing bacterial cellulose (BC) is proposed. Traditional BC production uses static culture conditions and produces a gelatinous membrane. The potential for using various types of bioreactor, including a stirred tank, conventional airlift, and modified airlift with a rectangular wire-mesh draft tube, in large ...

Bacterial cellulose (BC) can be used in medical, biomedical, electronic, food, and paper industries because of its unique properties distinguishing it from plant cellulose. BC production was statistically optimized by Gluconacetobacter xylinus strain using carob and haricot bean (CHb) medium.

The effect of pressure on viability and the synthesis of bacterial cellulose (BC) by Gluconacetobacter xylinus ATCC53582 were investigated. G. xylinus was statically cultivated in a pressurized vessel under 0.1, 30, 60, and 100 MPa at 25 degrees C for 6 days. G.

A new method for producing microcrystalline cellulose from Gluconacetobacter xylinus and kenaf
Carbohydrate Polymers, 2011Abstract A new preparation method of microcrystalline cellulose from Gluconacetobacter xylinus (BC) and kenaf (KF) is reported. The developed cellulose (DBC and DKF) materials showed different crystalline structures. DBC exhibited cellulose I lattice with high crystallinity (85%) whereas DKF showed cellulose II lattice with high crystalinity (70%).
