There has been a great deal of interest in the possible commercialization of the Zymomonas mohi/is-catalyzed process for oxidation of glucose to gluconic acid combined with the reduction of fructose to sorbitol. Sorbitol as well as sodium gluconate is used in a variety of industrial applications. The six patents listed in O Table 1.20, from 1988 to 1995, reflect examples of processes employing permeabilized cells of Z. mobilis. 

Use of biofilm reactors for ethanol production has been investigated to improve the economics and performance of fermentation processes.8 Immobilisation of microbial cells for fermentation has been developed to eliminate inhibition caused by high concentrations of substrate and product, also to enhance productivity and yield of ethanol. Recent work on ethanol production in an immobilised cell reactor (ICR) showed that production of ethanol using Zymomonas mobilis was doubled.9 The immobilised recombinant Z. mobilis was also successfully used with high concentrations of sugar (12%-15%).10... 

The first point at which C. thermocellum differs in ATP yield from organisms such as . coli or Zymomonas mobilis is the combined import of glucose and conversion to glucose-6-phosphate (G6P) [36]. Many organisms use an ABC transporter, PTS transporter, or symporter to import glucose into the cell (Figure 10.2a). Depending...
