Investigation of Physicochemical Properties of the Bacterial Cellulose Produced by Gluconacetobacter xylinus from Date Syrup
Bacterial cellulose, a biopolysaccharide, is produced by the bacterium, Gluconacetobacter xylinus. Static batch fermentation for bacterial cellulose production was studied in sucrose and date syrup solutions (Bx. 10%) at 28 °C using G. xylinus (PTCC, 1734). Results showed that the maximum yields of bacterial cellulose (BC) were 4.35 and 1.69 g/l00 ml for date syrup and sucrose medium after 336 ...
متن کاملBiotechnological Production of Cellulose by Gluconacetobacter Xylinus from Agricultural Waste
The purpose of this study was to utilize low quality date syrup, a rich and available source of nutrient in Iran, for the production of bacterial cellulose using Gluconacetobacter xylinus. Static batch fermentationfor the purpose of cellulose production by G. xylinus (PTCC, 1734) was studied using low quality date syrupand sucrose solution (Bx. 10%) as fermentation media at 28°C. Re...
متن کاملInfluence of nutritional factors on the nature, yield, and composition of exopolysaccharides produced by Gluconacetobacter xylinus I-2281.
The influence of substrate composition on the yield, nature, and composition of exopolysaccharides (EPS) produced by the food-grade strain Gluconacetobacter xylinus I-2281 was investigated during controlled cultivations on mixed substrates containing acetate and either glucose, sucrose, or fructose. Enzymatic activity analysis and acid hydrolysis revealed that two EPS, gluconacetan and levan, w...
متن کاملEffects of aromatic compounds on the production of bacterial nanocellulose by Gluconacetobacter xylinus
BACKGROUND Bacterial cellulose (BC) is a polymeric nanostructured fibrillar network produced by certain microorganisms, principally Gluconacetobacter xylinus. BC has a great potential of application in many fields. Lignocellulosic biomass has been investigated as a cost-effective feedstock for BC production through pretreatment and hydrolysis. It is well known that detoxification of lignocellul...
متن کاملAutonomous bottom-up fabrication of three-dimensional nano/microcellulose honeycomb structures, directed by bacterial nanobuilder.
We investigated the autonomous bottom-up fabrication of three-dimensional honeycomb cellulose structures, using Gluconacetobacter xylinus as a bacterial nanoengine, on cellulose honeycomb templates prepared by casting water-in-oil emulsions on glass substrates (Kasai and Kondo, Macromol. Biosci., 4, 17-21, 2004). The template film had a unique molecular orientation state along the honeycomb fra...
