Title: Separation method using single polymer phase systems
Inventor: VAN ALSTINE JAMES
IPC: C07K1/14
Filed: 2010-01-07
Abstract: The present invention relates to a process of enriching one target compound from a liquid, which process comprises at least one step of isolation performed by differentially partitioning between two aqueous phases. In the present invention the phases are formed by adding a thermally responsive, self-associating (i.e.  clouding) hydrophilic polymer, and if needed some additional salts, to an aqueous biotechnical solution (such as a fermentation sample or bioseparation process stream) under thermal and other conditions where the solution separates into a one polymer, two-phase system with one phase enriched in the polymer.  The target compound is to be found in the phase not enriched in the polymer, while a significant though varying percentage of contaminants may differentially partition to the phase interface or the polymer enriched phase. With minor or no modification the target containing phase solution can be further processed via standard unit operations such as precipitation, chromatography, and filtration to further purify target and remove any residual polymer.

IPC: C12N1/21
Filed: 2010-04-02
Abstract: This invention relates to the biocatalysts for the efficient production of succinic acid and/or other products from re-newable biological feedstocks. The biocatalysts have a very high efficiency for the growth-coupled production of succinic acid and/or other products from carbohydrate feed stocks as a result of both genetic manipulations and metabolic evolution. More specifically, certain biocatalysts of the present invention produce succinic acid at high titers and yield in mineral salts media dur-ing simple pH-controlled, batch fermentation without the addition of any exogenous genetic material. The genetic manipulations of the present invention are concerned with the energy-conserving strategies coupled with the elimination of alternative routes for NADH oxidation other than the routes for succinic acid production. The biocatalysts contain glucose-repressed gluconeogenic phosphoenol pyruvate carboxykinase (pck) derepressed by genetic modifications and a genetically-inactivated phosphotransferase system. In terms of succinic acid production efficiency, the biocatalysts of the present invention are functionally equivalent to suc-cinate producing rumen bacteria such as Actinobacillus succinogens and Mannheimia succiniproducens with one difference that the biocatalysts are able to achieve this high level of succinic acid production in a minimal salt medium with carbohydrate source as opposed to the requirement for a rich media for succinic acid production by rumen bacteria.
