Using wastewater after lipid fermentation as substrate for bacterial cellulose production by Gluconacetobacter xylinus

Carbohydrate Polymers, 2016
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

The production of bacterial cellulose in Gluconacetobacter xylinus regulated by luxR overexpression of quorum sensing system

Applied Microbiology and Biotechnology, 2021
Quorum sensing is a mechanism that facilitates cell-to-cell communication. Through signal molecular density for signal recognition, which leads to the regulation of some physiological and biochemical functions. Gluconacetobacter xylinus CGMCC 2955, which produces bacterial cellulose (BC), synthesizes the LuxR protein belonging to the LuxI/LuxR type QS ...

Utilization of Corncob Acid Hydrolysate for Bacterial Cellulose Production by Gluconacetobacter xylinus

Applied Biochemistry and Biotechnology, 2014
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.

Optimization of bacterial cellulose production by Gluconacetobacter xylinus using carob and haricot bean

International Journal of Biological Macromolecules, 2016
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.

Utilization of acetate buffer to improve bacterial cellulose production by Gluconacetobacter xylinus

Food Hydrocolloids, 2016
Abstract 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.

Effective in situ harvest of microalgae with bacterial cellulose produced by Gluconacetobacter xylinus

Algal Research, 2018
Abstract A new biological approach was explored to harvest microalgae in situ with bacterial cellulose produced by Gluconacetobacter xylinus grown in microalgal culture by adding different proportions of glucose/yeast extract (GY) media. This study attempted to optimize this process in terms of GY media concentration, process time, microalgae cell ...
