Genome sequence of a cellulose-producing bacterium, Gluconacetobacter hansenii ATCC 23769.

The Gram-negative bacterium Gluconacetobacter hansenii is considered a model organism for studying cellulose synthesis. We have determined the genome sequence of strain ATCC 23769.

Enhanced production of bacterial cellulose by using a biofilm reactor and its material property analysis.

Bacterial cellulose has been used in the food industry for applications such as low-calorie desserts, salads, and fabricated foods. It has also been used in the paper manufacturing industry to enhance paper strength, the electronics industry in acoustic diaphragms for audio speakers, the pharmaceutical industry as filtration membranes, and in the medical field as wound dressing and artificial skin material. In this study, different types of plastic composite support (PCS) were implemented separately within a fermentation medium in order to enhance bacterial cellulose (BC) production by Acetobacter xylinum.
