The Phytohormone Ethylene Enhances Cellulose Production, Regulates CRP/FNRKx Transcription and Causes Differential Gene Expression within the Bacterial Cellulose Synthesis Operon of Komagataeibacter (Gluconacetobacter) xylinus ATCC 53582
Komagataeibacter (formerly Gluconacetobacter) xylinus ATCC 53582 is a plant-associated model organism for bacterial cellulose (BC) biosynthesis. This bacterium inhabits the carposphere where it interacts with fruit through the bi-directional transfer of phytohormones. The majority of research regarding K. xylinus has been focused on identifying and characterizing structural and regulatory facto...
متن کاملTransgenic expression of Gluconacetobacter xylinus strain ATCC 53582 cellulose synthase genes in the cyanobacterium Synechococcus leopoliensis strain UTCC 100
We report the transfer of cellulose synthesis genes (acsABDC) from the heterotropic alpha proteobacterium, Gluconacetobacter xylinus strain ATCC 53582 to a photosynthetic microbe (Synechococcus leopoliensis strain UTCC 100). These genes were functionally expressed in this cyanobacterium, resulting in the production of non-crystalline cellulose. Although the cellulose lacks the structural integr...
متن کاملDirect Incorporation of Glucosamine and N-Acetylglucosamine into Exopolymers by Gluconacetobacter xylinus (5Acetobacter xylinum) ATCC 10245: Production of Chitosan-Cellulose and Chitin-Cellulose Exopolymers
Gluconacetobacter xylinus (5Acetobacter xylinum) ATCC 10245 incorporated 2-amino-2-deoxy-D-glucose (glucosamine) and 2-acetamido-2-deoxy-D-glucose (N-acetylglucosamine), but not 3-O-methyl-D-glucose or 2-deoxyD-glucose into exopolymers. Incorporation was confirmed by gas chromatography with and without mass spectrometry, Fourier transform infrared, and H nuclear magnetic resonance. The average ...
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 کاملInvestigation 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 ...
