| Abstract: | Bacterial cellulose was produced by Acetobacter xylinum subsp. surcrofermentans BPR2001 in a 50 liter air-lift reactor using fructose as the main carbon source. When air was supplied, the production of the cellulose was only 2.3 g/l in 80 h but when O -fortified air was supplied, the cellulose concentration increased to 5.63 g/l in 28 h and the productivity of the cellulose in an air-lift reactor with O -fortified air supply was comparable to that in a mechanically agitated jar fermenter. |
