Abstract
A process has been developed for the utilization of fructose by PTSmicroorganisms. Providing the microorganisms with increased fructokinase activity, and optionally with increased fructose transport capacity, allows the microorganisms to use fructose as a nutrient supply with sustained growth. The microbial production of substances such as cell mass, glycerol, and 1,3-propanediol may be achieved during growth in a fructose containing medium using this process.
