Abrégé
This invention relates to the production of succinic acid and other chemicals derived from phosphoenolpyruvate (PEP) by fermentation with a microorganism in which the fermentation medium contains one or more sugars, and in which one or more of the sugars is imported into the cell by facilitated diffusion. As a specific example, succinic acid is produced from a glucose-containing renewable feedstock through fermentation using a biocatalyst. Examples of such a biocatalyst include microorganisms that have been enhanced in their ability to utilize glucose as a carbon and energy source. The biocatalysts of the present invention are derived from the genetic manipulation of parental strains that were originally constructed with the goal to produce one or more chemicals (for example succinic acid and/or a salt of succinic acid) at a commercial scale using feedstocks that include, for example, glucose, fructose, or sucrose. The genetic manipulations of the present invention involve the introduction of exogenous genes involved in the transport and metabolism of glucose or fructose into the parental strains. The genes involved in the transport and metabolism of glucose or fructose can also be introduced into a microorganism prior to developing the organism to produce a particular chemical. The genes involved in the transport and metabolism of sucrose can also be used to augment or improve the efficiency of sugar transport and metabolism by strains already known to have some ability for glucose utilization in biological fermentations.

This invention relates to the metabolic evolution of a microbial organism previously optimized for producing an organic acid in commercially significant quantities under fermentative conditions using a hexose sugar as sole source of carbon in a minimal mineral medium. As a result of this metabolic evolution, the microbial organism acquires the ability to use pentose sugars derived from cellulosic materials for its growth while retaining the original growth kinetics, the rate of organic acid production and the ability to use hexose sugars as a source of carbon. This invention also discloses the genetic change in the microorganism that confers the ability to use both the hexose and pentose sugars simultaneously in the production of commercially significant quantities of organic acids.
