Abstract: In the present work. the use of flame-burned WS as c k e r s of 2. mobilis and extracellular levansucrase and the effect of the cell fixation method by dehydration on system productivity were investigated. Lyophilization and convective drying of 2 mobilis biomass at 30 "c to a moisture content of 10-14 % gave the best results for the repeated batch fermentations of a sucrose medium to obtain levan and ethanol. Significant correlation between the product formation and the concentration of free cells in the fer…
