20160083753 | METABOLIC EVOLUTION OF ESCHERICHIA COLI STRAINS THAT PRODUCE ORGANIC ACIDS - 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. | 03-24-2016 |
20150329887 | INTEGRATED BIOREFINERY - This invention relates to the operation of a biorefinery for manufacturing either biofuels or renewable chemical feedstock using lignocellulosic biomass as a source of carbon. The present invention provides a cost-effective process for pretreating lignocellulosic biomass in the recovery of fermentable sugars. More specifically, the present invention describes an integrated approach for efficiently recovering and using six-carbon and five-carbon sugars along with value-added oligosaccharides such as xylooligosaccahrides from lignocellulosic biomass so that the cost of manufacturing biofuels and renewable chemical feedstock is substantially lowered. | 11-19-2015 |

20130337519 | METHOD OF PRODUCING SUCCINIC ACID AND OTHER CHEMICALS USING SUCROSE-CONTAINING FEEDSTOCK - This invention relates to the production of chemicals by fermentation with a microorganism in which the fermentation medium contains the sugar sucrose. As a specific example, succinic acid is produced from a sucrose-containing renewable feedstock through fermentation using a biocatalyst. Examples of such a biocatalyst include microorganisms that have been enhanced in their ability to utilize sucrose 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 other than sucrose. The genetic manipulations of the present invention involve the introduction of exogenous genes involved in the transport and metabolism of sucrose into the parental strains. The genes involved in the transport and metabolism of sucrose 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 sucrose transport and metabolism by strains already known to have some ability for sucrose utilization in biological fermentation. | 12-19-2013 |
